Frequently Asked Questions
What is the primary difference between a Brush DC Motor and a Brushless DC Motor?
Brush DC Motors use commutation brushes which change the direction current flows periodically to maintain torque. Because of brush wear, a Brush DC Motor requires more maintenance and has shorter life than Brushless DC Motors. Instead of brushes, Brushless Motors use Hall Sensors which are placed at the back end of the motor. These Hall Sensors output high-low pulses when they detect a change in magnetic field. For this reason, Brushless DC Motors require the use of more complex circuitry found in Variable Speed Drives (VSD). Also, since Brushless DC Motors do not use brushes for commutation purposes, they are far more efficient, require very low maintenance and have a longer life than Brush DC Motors.


Helpful Information
What are Brushless DC Motors
Brushless DC motors are also known as BLDC Motors; synchronous electric motors that are DC (Direct Current) powered. They are electronically commutated without brushes making them “Brushless”. Brushless DC Motors consist of a fixed armature along with permanent magnets that rotate, hall sensors, stator windings, rotor magnet North and South, hall sensor magnets, an accessory shaft, and a driving end of the shaft.

Accessories
At Anaheim Automation you will see that we provide different accessories for our Brushless DC Motors. These accessories include a brake, encoder, connector, cable and a driver. The Brushless DC Motors brake is a 24vdc system. These Brushless DC Motors brakes are perfect for any holding applications. Each brake that we offer is already available on any Brushless DC Motors, and already attached to the rear of the Brushless DC Motors. Our Brushless DC Motors brakes have a low voltage design for applications that are susceptible to brown out, weak batter, or long wiring runs. When electric power is applied to the Brushless DC Motors brake the armature is drawn by the electromagnet force in the magnet body assembly, which overcomes the spring action. By overcoming the spring action the friction disc will rotate freely. When electrical power is interrupted, the electromagnetic force is removed and the pressure spring mechanically forces the armature plate to clamp the friction disc between itself and the pressure plate. The Brushless DC Motors cables if requested can be provided with the Brushless DC Motors connector, or can be ordered from Anaheim Automation.

Advantages and Disadvantages for Brushless DC Motors
Some of the advantages of Brushless DC Motors, but are not limited to are: • Higher speed ranges • High dynamic response • Long operating life • Better speed versus torque characteristics • Noiseless operation • High efficiency Disadvantages for Brushless DC Motors • High cost • Additional system wiring is required to power the electronic commutation circuitry • Motion controllers/drivers electronics needed to operate Brushless DC Motors are more complex

Consumer Electronics
Consumer Electronics Although Brushless DC motors may perform the same functions originally fulfilled by brushed DC motors, cost and control complications prevent Brushless DC motors from completely replacing brushed motors. However, Brushless DC motors have monopolized many areas of the consumer electronics industry, and are used in many different locations, including computer hard drives and CD/DVD players. Brushless DC motors are used to operate the small cooling fans that are located in electronic equipment as well. Cordless power tools also utilize BLDC motors because the need for increased efficiency of the BLDC motor allows for long periods of use before needing to recharge the battery. Furthermore, direct-drive turntables for ?analog? audio disks use low-speed, low-power Brushless DC motors. Transport Electric and hybrid vehicles use high power Brushless DC motors that are essentially AC synchronous with permanent magnet rotors. Brushless DC motors are used in Segway and Vectrix-Maxi-Scooters also. Electric bicycles sometimes build Brushless DC motors into their wheel hubs, with the stator solidly fixed to the axle and magnets attached to and rotating with the wheel. These electric bicycles have a standard bicycle transmission with pedals, sprockets, and chain that, if needed, can be pedaled along with or without the use of the Brushless DC motors. Heating and Ventilation It has become a popular trend to switch from AC motors to BLDC motors (EC) because of the dramatic reduction in power needed o run them, versus the typical AC motor. Although shaded-pole and permanent split capacitor motors were the primary fan motor of choice, many fans today are being run by BLDC motors. Some use BLDC motors simply to increase system efficiency as a whole. Certain HVAC systems use ECM motors (electronically commutated BLDC motors). Particularly these are the HVAC systems that feature load modulation and/or variable-speed. BLDC motors not only have higher efficiency, but also a built-in microprocessor that allows for better airflow control, programmability, and serial communication. Model Engineering and Hobbyists The most popular motor choice for model aircraft today are BLDC motors. The BLDC motors are available in a wide array of sizes, and have a favorable power to weight ratios. BLDC motors have transformed the market of electric-powered flight. The introduction of BLDC motors has displaced the use of almost all brushed electric motors in model aircraft and helicopters. Modern batteries and BLDC motors allow model airplanes to vertically ascend, versus gradually climb. Small glow fuel internal combustion engines that were used in the past are no comparison to the silent and clean BLDC motors. BLDC motors have also increased in popularity among the Radio Controlled (RC) cars, buggies, and trucks, where sensor-type BLDC motors allow the position of the rotor magnet to be detected. Many BLDC motors feature upgrades and replaceable parts like sintered neodymium-iron-boron (rare earth magnets), replaceable motor timing assemblies, and ceramic bearings. As a result, these BLDC motors are quickly ascending to the top of the list as far as preferred motor types for electric on and off-road RC racers. BLDC motors have low-maintenance, high reliability and power efficiency ~ most BLDC motors with an efficiency rating of 80% or more.

Medical Applications
Brushless DC Motors have become popular amongst the medical industry for its long-lasting design. Used in medical equipment, Brushless DC motors have a life expectancy of 10,000 hours, versus the 2,000-5,000 hour lifespan of the brushed motor. Brushless DC motors also have a top speed that is not limited by a large number of poles. It wasnt until the cost of these Brushless DC Motors decreased, that they became a viable option for most medical applications. Brushless DC motors can provide a more efficient, reliable, and compact motor that can be used in a variety of ways. Basically, Brushless DC motors aresynchronous electric motors that are powered by a DC power source. An electric commutation circuit replaces the standard commutator and brush assembly found in the brushed DC motor. Brushless DC motors and brushed DC motors are essentially polar opposites. While the windings of Brushed DC motors rotate around the rotating shaft or armature, the brushless DC motors have windings that are attached to the motor housing. The magnets of the Brushed DC Motors attach to the motor housing, while Brushless DC motors magnets are affixed to the rotor. Commutation is the process of reversing the polarity of the phase currents in the windings of the motor at an exact time that will produce continuous rotational torque. If commutation did not occur, the magnets and magnetic fields would lock the rotating shaft in place by aligning themselves. The appropriate reversal time is crucial; the brushless DC motor shaft must continue spinning, and it does so as a result of the changing polarity of the windings. The primary way Brushless DC motors and a brushed DC motors differ is in their methods of commutation. Brushed DC motors use brushes and a commutator that acts as an electromechanical switch to connect the windings in the proper polarity. In Brushless DC motors, electronic switches take the place of the mechanical switch, controlling the timing of the polarity-reversal by an electrical circuit. Usually, Brushless DC Motors sense rotor position and controls the electronic drive of Brushless DC Motors by using Hall-effect devices (HFD). However, because of the ability to monitor motor back-EMF, HFD can be eliminated to create a sensorless Brushless DC motors drive. These motors are far less expensive, and are a primary reason they appeal in medical equipment design. Sleep Apnea can also be treated with the help of Brushless DC Motors. Treatment for the disorder requires the use of Positive Airway Pressure (PAP) respirators. The PAP respirator is attached to a special breathing mask that the patient must wear to breathe through while sleeping. Within the respirator is a blower fan that pressurizes the air mask, according to the patients breathing pattern. As the patient inhales, the blower fan speeds up, allowing more air to reach the lungs. Oppositely, when the patient exhales, the blower fan slows down to reduce the amount of air the patient breathes out. Brushless DC motors never need to operate underneath the minimum threshold speed of the drive, so they are the perfect power source for blower fans. Furthermore, there is no risk for any sudden changes in load. Low-noise-level standards force hospital equipment to be as quiet as possible, thus making Brushless DC Motors a prime candidate due to how silent they are in operation. Brushless DC Motors can operate at high speeds with accuracy, and yet maintain a silent sound. Therefore, they can be used both in hospitals, and in the patients home. It is the absence of a commutator and brushes in Brushless DC motors that removes even more of the motor noise.

Applications
Brushless DC Motors are utilized in a variety of applications in many different industries. For example some of many applications are CNC, Aerospace, Semiconductor, Packaging Equipment, Automotive, Instrumentation, Applicances, Medical, and Consumer.

Basic Types
All Brushless DC Motors are permanent magnet motors. There are also two basic types labeled as a Trapezoidal Motor and the other as a Sine Wave Motor. The Trapezoidal Motor is said to be a DC servo motor and the Sine Wave Motor has close resemblance to an AC synchronous motor.

Basics
The basic definition for Brushless DC Motors are an automatic device that uses an error-correction routine to correct the motion of the Brushless DC Motors. The general term Brushless can be applied to systems other than a Brushless DC Motors that use a feedback mechanism such as an encoder or other feedback device to control the motion parameters. Typically when the term Brushless is used it applies to Brushless DC Motors but this term is also used as a general control term with the meaning of a feedback loop to position whatever the item iA standard definition for Brushless DC Motors are an automatic machine that uses error-correction rountine to correct the motion of the Brushless DC Motors. The general term Brushless DC Motors can be applied to systems other than Brushless DC Motors that use a feedback mechanism such as an encoder or other feedback device to control the motion parameters. Typically when the term Brushless DC Motors are used it applies to Brushless DC Motors but this term is also used as a general control term with the meaning of a feedback loop to position whatever the product is including a Brushless DC Motors items. Brushless DC Motors differ from other controlled motors because its controlled by a time-based derivative commonly known to as the PID loop. A Brushless DC Motors are used must be capable to change the velocity (rate of change of position) of the output shaft because the time-based derivative.

Construction
The Stator The stator of Brushless DC Motors consists of stacked steel laminations the windings are positioned in the slots that are cut inside the laminations. The stator of a Brushless DC Motors is equivalent to that of an AC motor however the windings are different. There are three stator windings in each Brushless DC Motors hooked up in either a Delta or star configuration. Each of these windings there are multiple coils that are constructed to connect together to form a winding. Anaheim Automation typically has six coils per Brushless DC Motors which are made into a three-phase winding. There is usually an even number of polls. Mainly there two types of stator windings, sinusoidal and trapezoidal. The difference in the stator windings is identified in the interconnection of the coils of the stator windings. Which result in a different type of back EMF the trapezoidal variant delivers its back EMF in shape of a trapezoid. Each sinusoidal variation gives its Brushless DC Motors a back EMF that matches with the current. The faulted also is used as the shape of the sinusoid and a trapezoid. The difference between the two Brushless DC Motors is that the sinusoidal Brushless DC Motors have smoother output torque than that of a trapezoidal Brushless DC Motors. The stator will winding can be wound for multiple folk voltages. This can be customized for almost any distinct applications are speed and torque requirements. The Rotor The rotor is made up of permanent magnets and normally has between two and eight poles the magnets are bonded onto the rotor core in alternating north and south pole fields. Permanent magnet rotors are generally constructed with Ferrite magnets. If a higher power density is needed in an application rare earth magnets are being generally used. The ferrite magnets are less expensive, but the flux density is lower than that of the rare earth magnets. The price of rare earth magnets is also coming down. Higher power density means that the Brushless DC Motors can put out much more torque in a smaller volume which is helpful to manufacturers that are continuously pushed provide smaller and smaller packages. Rare earth magnet types: Neodymium (Nd) Samarium Cobalt (SmCo) The alloy of Neodymium, Ferrite, and Boron (NdFeB)

Cost
Brushless DC Motors vary in price. They can be anywhere from twenty dollars or less to several hundred dollars, possibly more. It just depends on the size and capabilities of the Brushless DC Motors themselves.

While every effort is made to offer solid advice regarding the Brushless DC Motors, as well as other motion control products, and to produce technical data and illustrations accurately, such advice and documents are for reference only, and subject to change without notice.

Encoder Feedback
For low-speed products it is recommended to use an encoder for the feedback rather than the Hall sensors. The number of counts per revolution for the Hall sensor can only be as large as the number of polls times the number of Hall Sensors. When operating the Brushless DC Motors, the Brushless DC Motors Controllers can utilize the higher count to its advantage. The Brushless DC Motors controllers can use the additional information with more counts per revolution at its disposal for more precise control of the velocity. The higher the resolution on the encoder the more finely the Brushless DC Motors controllers can control the Brushless DC Motors. Though when evaluating prices yes the encoder is more expensive than the Hall sensor, but with the encoders you receive precise control at a lower cost than alternate technologies such as AC motors, Servo motors, or Synchronous motors.

Environmental Considerations
The following environmental and safety considerations must be observed during all phases of operation, service and repair of a Brushless DC Motors system. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the Brushless DC Motors and controller. Please note that even a well-built Brushless DC Motors products operated and installed improperly, can be hazardous. Precaution must be observed by the user with respect to the load and operating environment. The customer is ultimately responsible for the proper selection, installation, and operation of the Brushless DC Motors system. The atmosphere in which a Brushless DC Motors are used must be conducive to good general practices of electrical/electronic equipment. Do not operate the Brushless DC Motors in the presence of flammable gases, dust, oil, vapor or moisture. For outdoor use, the Brushless DC Motors and controller must be protected from the elements by an adequate cover, while still providing adequate air flow and cooling. Moisture may cause an electrical shock hazard and/or induce system breakdown. Due consideration should be given to the avoidance of liquids and vapors of any kind. Contact the factory should your application require specific IP ratings. It is wise to install the Brushless DC Motors and controller in an environment which is free from condensation, electrical noise, vibration and shock. Additionally, it is preferable to work with the Brushless DC Motors and controller system in a non-static protective environment. Exposed circuitry should always be properly guarded and/or enclosed to prevent unauthorized human contact with live circuitry. No work should be performed while power is applied. Don t plug in or unplug the connectors when power is ON. Wait for at least 5 minutes before doing inspection work on the Brushless DC Motors system after turning power OFF, because even after the power is turned off, there will still be some electrical energy remaining in the capacitors of the internal circuit of the Brushless DC Motors controller. Plan the installation of the Brushless DC Motors and controller in a system design that is free from debris, such as metal debris from cutting, drilling, tapping, and welding, or any other foreign material that could come in contact with circuitry. Failure to prevent debris from entering the Brushless DC Motors system can result in damage and/or shock.

First Use of Brushless DC Motors
It is said that Brushless DC motors have been in commercial use and possible since 1962, although the first Brushless DC motors appeared during the 1800s. This was made possible by the conversion of electrical energy into mechanical energy by electromagnetic means, which was demonstrated by a British scientist by the name of Michael Farady in 1821. A Hungarian physicist by the name of Ányos Jedlik began experimenting with devices he called electromagnetic self-rotors in 1827. At the time, they were only used for instructional purposes. In 1828, he demonstrated the first device to contain the three main components of practical direct current dc motors; the rotor, commutator, and stator. The magnetic fields of both the revolving and stationary components were produced solely by currents flowing through their windings and the dc motors did not contain permanent magnets in those times. In 1832, William Sturgeon, also a British scientist invented the first commutator-type direct current electric motor capable of turning machinery. Americans, Thomas and Emily Davenport built a commutator-type direct current electric motor with the intention of commercial use in following Sturgeon’s work and patented in 1837. The dc motors were used for a printing press and powered machine tools. They were said to have ran up to 600 revolutions per minute (RPM). The Brushless DC Motors were commercially unsuccessful due to the high costs of the primary battery power, also there was no practical commercial market for the Brushless DC Motors at that time. Modern Brushless DC motors was accidently invented in 1873, when a dynamo was to a similar motor driving it as a motor by Zénobe Gramme. He then created the Gramme Machine, it was the first electric motor that was successful in the industry. A non-sparking motor capable of constant speed under variable loads was the first practical Brushless DC motors were invented in 1886 by Frank Julian Sprague.

Hall Sensor Feedback
The use of Hall Sensors makes feedback when rotating the Brushless DC Motors stator windings that are sequentially energized. In order to understand the next winding that would need to be energized in the proper sequence, the controller needs to know the rotor position. The rotor position is sensed by the Hall sensors embedded in the back end cap of the Brushless DC Motors housing. The Brushless DC Motors utilizes three Hall sensors. They are divided by either 60° or 120°. Hall sensors sense either the rotor magnet or external magnet placed in the back of the shaft, and sends off a signal signifying whether or not a North or South Pole passes the censors. Using each signal from the sensors, the Brushless DC Motors controller can easily maintain the Brushless DC Motors velocity. Each Hall sensor normally mounted on a PC board and fastened to the back end cap on the non-driving end of the Brushless DC Motors.

Housing
Brushless DC Motors types now days are manufactured with the housing less design where the laminations are exposed and coated with a paint to prevent rusting from occurring. Some Brushless DC Motors types are still housed in an extrusion or aluminum or steel cylindrical housing and the laminations of the stator are placed and secured in that housing.

How are Brushless DC Motors controlled
Most Brushless DC Motors need a controller/driver to run. There are many different types of controllers/drivers that are manufactured around the world for different applications. Many come with different options and can be custom made. Most are referred to as Electronic Speed Controller (ESC). In a Brushless Controller/Driver, either a Hall Effect Sensor or the Back EMF (Electromotive Force) is used to run the motor. The Hall Effect uses three hall sensors within the motor to help detect the position of the rotor. This method is primarily used in speed detection, positioning, current sensing, as well as proximity switching. The magnetic field changes in response to the transducer that varies its output voltage. A feedback is created by directly returning a voltage since the sensor operates as an analogue transducer. The distance between the Hall plate and a known magnetic field can be determined with a group of sensors, in this case, three, and the relative position of the magnet can be deduced. A Hall sensor can act as an on/off switch in a digital mode when combined with circuitry. The Back EMF, also known as the Counter-Electromotive Force is caused by a changing electromagnetic field. In Brushless DC MotorS, the back EMF is a voltage that occurs where there is motion between the external magnetic field and the armature of the motor. In other words, the voltage is developed in an inductor by and alternating current or pulsating current. At every moment, the polarity of the voltage is the reverse of the input voltage. This method is commonly used to measure the motor’s position and speed indirectly.

How Do Brushless DC Motors Work
Brushless DC motors have an electronic commutation system, no brushes and no mechanical commutators. This allows the Brushless DC Motors to operate at higher speeds. There can be a different amount of poles on the stator for each motor.

How to select Brushless DC Motors
When selecting Brushless DC Motors, you want to ask yourself a few questions. Such as, what is my application? What are my specifications? How much do I want to spend? What controller/driver and I going to use/need? These are some of the questions you want to think about to narrow down your selection. You will definitely want to do your research. The type of application will need to be determined for your Brushless DC Motors. You will then need to determine all specifications, known ones along with possible ones. For example, do you need a specific frame size, weight, power, speed, length, etc. Once you have determined all those things, you will need to take into consideration on what controller/driver you will be using. This goes hand in hand with the selection of the motor. Keep in mind there are many different motors and driver/controllers to choose from, therefore it is wise to do detailed research.

Modern day uses of Brushless DC Motors
Brushless DC Motors have and continue to rise in popularity for many different applications. Although, Brushless DC Motors may cost a little more than DC Brushed Motors, they have far more advantages than disadvantages. Many industries have turned to Brushless motors for their applications. For specific Industries, please check the “What Industries are Brushless DC Motors used in” section.

Mounting
The following information is designed as a overall guideline for the installation and mounting of Brushless DC Motors systems. WARNING - Dangerous voltages are capable of causing injury or death may be present in the Brushless DC Motors systems. Use extreme caution when handling, testing, and adjusting during installation, set-up, and operation. It is very important that the wiring of Brushless DC Motors and controllers be taken into consideration upon installation and mounting. Subpanels installed inside the enclosure for mounting Brushless DC Motors systems components, must be a flat, rigid surface that will be free from shock, vibration, moisture, oil, vapors, or dust. Remember that the Brushless DC Motors and controllers will produce heat during work; therefore, heat dissipation should be taken into consideration in designing the system layout. To be sure not to exceed the maximum ambient temperature rating, size the enclosure. It is suggested that the Brushless DC Motors controllers be mounted in position as to provide adequate airflow. The Brushless DC Motors needs to be mounted in a stable fashion, secured tightly. NOTE: There must be a minimum of 10mm in between the Brushless DC Motors controllers and any other devices mounted in the system/electric panel or cabinet. NOTE: in order to comply with CE and UL standards, the Brushless DC Motors systems must be grounded in a grounded conducive enclosure offering protection as defined in standard EN 60529 (IEC 529) to IP55 such that they are not accessible to the operator or unskilled person. As with any active part in a system, the Brushless DC Motors should be kept out of the reach of the operator. A NEMA 4X enclosure surpasses those requirements providing protection to IP66. To improve the bond between the power rail and the subpanel, construct your subpanel out of zinc-plated (paint-free) steel. Additionally, it is strongly suggested that the Brushless DC Motors controllers be protected against electrical noise interferences. Noise from signal wires can cause mechanical vibration and malfunctions.

Physical Properties of Brushless DC Motors
Brushless DC Motors have the physical appearance of a 3-phase permanent magnet that is stationary which is located on the outside, which is known as the Stator. The rotating armature is located inside and is also called the rotor. Brushless DC Motors can be constructed in many different physical configurations. One configuration is known as the “Inrunner” type where the permanent magnets are a part of the rotor and three stator windings are surround the rotor. Another configuration is the “Outrunner” type, where the radial-relationship between the coils and magnets is reversed. The stator coils form the core of the motor, while permanent magnets spin within an overhanging rotor surrounding the core.

Motor Life Cycle
The key dissimilarity between brushless motors and their predecessors is the process of commutation. Newer brushless DC motors are electrically commutated; this is accomplished with Hall elements, by counter EMF, or encoder feedback. Factors That Affect Motor Life Bearing failure is a major factor when it comes to brushless DC motors failing. As a result of using industrial grade components, some brushless DC motors have the ability to last lifetimes in excess of 20,000 hours or more. Integrated into these systems are permanently lubricated ball bearings that use special grease, thus eliminating the need for re-lubrication. Non-approved lubricants are not recommended for the brushless DC motor components because they could potentially shorten the life of the brushless DC motor. Temperature also plays a key role in the lifespan of a brushless DC motor.The brushless DC motor casing in particular must ensure that the heat generated in the motor windings must be dispelled. The brushless DC motor may face severe damage if it exceeds the specification regarding heat. The motors performance has a direct correlation with the maximum possible rotor temperature, ambient temperature, and duty cycle. As temperature increases, the winding resistance increases, and magnetic forces decrease, ultimately causing performance to dwindle. When running at high continuous loads, all of these factors must be taken into consideration. Heat sinking and forced air-cooling can considerably lower operating temperatures.

Newer Brushless DC motors are electrically commutated; this is accomplished with Hall elements, by counter EMF, or encoder feedback. Brushless DC motors are very useful and cost-effective by their design and construction. However, there are some factors that can negatively affect the life expectancy of the Brushless DC motor: Key Points to Remember - • Bearing failure and lack of lubrication are major factors when it comes to Brushless DC motors failing. As a result, manufacturers now use industrial grade components so that some Brushless DC motors now have the ability to last lifetimes in excess of 20,000 hours or more!

Brushless DC motor performance has a direct correlation with the maximum possible rotor temperature, ambient temperature, and duty cycle. As temperature increases, the winding resistance increases, and magnetic forces decrease, ultimately causing Brushless DC motors to perform less efficiently. • When Brushless DC motors run at high continuous loads, heat sinking and forced air-cooling can considerably lower operating temperatures. Therefore, it is highly recommended that all of these factors be taken into consideration when designing and installing motion control systems that include Brushless DC motors.

Wiring
The general information provided in the following paragraphs is designed to be a guideline for wiring the Anaheim Automation Brushless DC Motors. System faults and communication errors can result from routing power and signal wiring on a machine or system, also radiated noise from the close by relays, transformers, and electronic devices can be inducted Brushless DC Motors and encoder signals, other sensitive low voltage signals, and input/output communications. WARNING - When you reach dangerous voltages, your Brushless DC Motors system is capable of causing injury or death. Use extreme caution when testing, handling, adjusting, and wiring during tuning, set-up, installation, and operation. To refrain from mechanical vibration that can lead to failure and/or loss, dont make extreme changes or adjustments to the Brushless DC Motors system parameters. Do not directly turn On/Off the power supply from the Brushless DC Motors Controllers when the Brushless DC Motors are wired. You will decrease the lifetime of the Brushless DC Motors systems by aging the internal components by frequently switch the power On/Off. Strictly comply with the following rules: - Follow the Wiring Diagram with each Brushless DC Motors - Route high-voltage power cables independently from low-voltage power cables. - Segregate input power wiring and Brushless DC Motors power cables from control wiring and Brushless DC Motors feedback cables as they leave the Brushless DC Motors controller. Maintain this separation throughout the wire run. - Use shielded cable for power wiring and provide a grounded 360 degree clamp termination to the enclosure wall. Enable room on the sub-panel for wire bends. - Make all cable routes as short as possible. NOTE: Factory made cables are ideal for use in our Brushless DC Motors and driver systems. These cables are purchased separately, and are designed to minimize EMI. These cables are suggested over customer-built cables to enhance system performance and to produce additional safety for the Brushless DC Motors system and the user. WARNING - To avoid the risk of electrical shock, perform all mounting and wiring of the Brushless DC Motors and controllers system prior to applying power. Once power is applied, connection terminals may have voltage present.
