Fundamentals of AC Motors

Frequently Asked Questions
What is the best way to test AC Motors?
1. If high current is being drawn from the motor, it may indicate a bent shaft or an issue with the motor bearings. Remove power from the motor system. If needed, switch off the circuit breaker connected to the unit to prevent injury.

2. For AC Motors using Start-Up Capacitors:
If the motor makes a humming sound, fails to rotate under the full load and produces high current it may be a bad start up capacitor. If the capacitor is of a large value, wait 30 minutes to an hour to allow some of the charge to dissipate. After doing so, discharge the remaining charge stores in the capacitor by shorting out the terminals together with an insulated screwdriver. While holding the plastic insulated handle, place the tip of the screwdriver against one of the terminals and come across with the screwdriver shaft to make a connection with the other terminal. A small or big spark may be seen depending on the amount of charge remaining in the capacitor. Using an Digital Multimeter, measure the resistance across the two terminals. If '0' resistance is read, then the capacitor is shorted and needs to be replaced.

3. To make sure an AC Motor is operating correctly, test the windings of the motor. Using a Ohmmeter (Digital Multimeter) set the resistance reader setting. Touch both leads together to make sure meter reads zero ohms. Next, use the ohmmeter to measure the resistance of each winding (phase). Each winding should have a small resistance and should not be open or indicate a short. If a short is detected then the motor is no longer working properly and must be changed.

What are the main components of AC Motors?
The main components of an AC Motor are the stator, rotor, mount and enclosures.

Stator
The stator is the primary winding component of an AC Motor. As the name suggest, it is the stationary part of the motor and also connected to the power supply. Electromagnets are placed inside the hollow surface of the cylindrical stator. One pole of the magnet is set facing the center while the other is facing rotor. The alignment of these magnets are designed in a way where they are able to attract and repel the poles of the rotor. This creates a continuous magnetic field to turn the rotor without stopping it.

Rotor
The rotor is the rotating component of AC Motors. The construction of the rotor is the same as the stator but the rotor is a solid cylinder with a shaft on its center. Again, the electromagnets of the rotor face the poles of the electromagnets of the stator. The interaction between these poles found in the stator and rotor cause the rotor and the shaft to rotate. The rotor is able to rotate due to the electromagnet poles of the stator attracting and repelling the poles on the rotor. This phenomenon creates a magnetic field which allows the AC motor to run.

Mount
The mount is the component of the AC Motor which holes the stator. Mounting options vary from manufacturer to manufacturer. Some mounting options include Leg (Foot) Mount, Flange Mount, Base Mount and etc. These various options allow a user to orient the position and mounting style of the AC Motor for their application needs.

Enclosures
Enclosures are casings which are designed to protect the motor and control from heat generated by the motors windings. Two of the most common types are Totally Enclosed Fan Cooled (TEFC) and Open Drip Proof (ODP). The TEFC type enclosures provide dust-tight and water-seal protection features. They come equipped with an external fan attached to rear of the motor's shaft. This feature is key in cooling the surface of the casing but also the motor windings. ODP enclosures are made of metal sheets with intake and exhaust vents and internal fans which cool the motor windings through those vents.

Why would one choose a Three Phase AC Motor over a Single Phase AC Motor?
Three Phase AC Motors are more cost-effective, and compact than single phase motors with the same rating and voltage. Single Phase AC Motors above 10 HP (7.5 kW) are typically not as common. Three phase motors vibrate less, therefore have an extended life compared to single phase motors of the same power, used under the same conditions. Single phase motors require resistors or capacitors in order run motor, where as a three phase motor is able to be plugged straight into the wall to operate.



Can I reverse the direction of rotation of the AC Induction motor if I wired it as shown on the catalog, for example, ACP-M-4IK25N-AU?
Yes, you can reverse the AC Motors direction of rotation as shown in the catalog. However, for precautionary measures, it is highly recommended to stop the motor completely prior to changing directions to avoid harm and/or motor damage. If immediate reversing is needed, a reversible motor is better suited for the application; for example ACP-M-4RK25N-AU.

Can the speed of AC Induction Motors and Reversible motors be changed?
The power supply frequency determines the speed a single-phase (AC) induction and reversible motor will run. If your application necessitates a change in speed of your AC Motors, a speed controller is recommended.

Will temporarily storing my AC Induction Motor in an environment of 0°F to -20°F create any problems?
Extreme temperature changes might lead to condensation inside the AC Motors. If this happens, components may rust, greatly shortening the service life. Do your best to avoid the occurrence of condensation.

Will an AC Induction Motor be affected by large fluctuations in power supply voltage?
The power supply voltage affects the torque produced by the AC Motors. Torque is equal to approximately two times the power supply voltage. Thus, when using motors under large power voltage fluctuations, it is important to remember that the generated torque will vary.

What is the lifetime rating of an AC Induction Motor?
The ACW Induction motors have a rated lifetime of 2,000 hours if operated under the rated conditions such as torque and speed.

The ACP-M Induction motors have a rated lifetime of 5,000 hours if operated under the rated conditions such as torque and speed.

The lifetime of AC Motors can change due to environmental exposure such as heat, wet or damp environments, bearing lubrication, winding insulation (motor IP rating) and stator steel lamination. By buying the appropriate motor, many limiting factors on lifetime can be negated.

Is a capacitor required for the AC Industrial motors?
The three phase AC Input Voltage allows for three overlapping current cycles to drive the magnetic coils inside ac motors. The phase difference of these inputs to the motor windings are 120 degrees apart which allows a Three Phase AC Industrial Motor to run without the use of a start-up capacitor. On the other hand, Single-Phase Motors require a capacitor in order to create a lag between the input voltage and the phase to allow the motor to rotate.

Accessories
There is a vast selection of accessories for the AC Motors. The accessories available include a brake, clutch, fan, connector, and cables. The AC Motors brakes are a 24vdc system. These brakes are ideal for any holding applications you may use with an AC Motor. The AC Motors brakes have a low voltage design for applications that are susceptible to weak battery, brown out, or long wiring. The AC Motors Clutch is used to control the torque that is applied to the load. The AC Motors clutch can also be used to ramp up the speed of a high inertia load. Clutches are ideal to use with an AC motors when you want precise control over torque or to slowly apply the power. AC Motors clutches also help prevent large current spikes. AC Motors Fans are used to cool down the motors. They are not really seen in small motors because they are not needed but more common with larger AC induction motors due to heat generation. There are two types of fans that are used for AC Motors. The types are internal and external fans. AC Motors fans are ideal to use when overheating is a concern. AC Motors cables can be custom made with the supplied AC motors connector to fit your specifications. The cables may also be purchased from Anaheim Automation.

Basics
The standard definition for AC Motors is electric motors that use and are driven by alternating current. AC Motors are used in the conversion of electrical energy into mechanical energy. This mechanical energy is made from utilizing the force that is exerted by the rotating magnetic fields produced by the alternating current that flows through coils. The AC Motors is made up of two components. AC Motors components are the stationary stator that is on the outside and has coils supplied with AC current, and the inside rotor that is attached to the output shaft.

Cost
The AC Motors are a reasonable cost effective solution to your application needs. The construction materials along with how the motors is designed make AC Motors affordable solutions. AC Motors operate with a rotating magnetic field and does not use brushes. This enables the cost of the motors to be lower and eliminates a piece of your motors that wears over time. AC Motors do not require a driver to operate. This saves initial setup costs. Today’s manufacturing processes makes producing AC Motors easier and quicker than ever. The stator is made out of thin laminations that can be pressed or punched out of a machine. Many other parts can be quickly made and perfected saving both time and money.

Customizing AC Motors
Anaheim Automation was established in 1966 as a manufacturer of turnkey motion control systems. Its emphasis on R&D has insured the continued introduction of advanced motion control products, such as the AC Motors product line. Today, Anaheim Automation ranks high among the leading manufacturers and distributors of motion control products, a position enhanced by its excellent reputation for quality products at competitive prices. The AC Motors product line is no exception to the Company’s goal. Anaheim Automation offers a variety of standard AC Motors. Occasionally, OEM customers with mid to large quantity requirements prefer to have AC Motors that are custom or modified to meet their exact design requirements. Sometimes the customization is as simple as shaft modification, brake, oil seal for an IP65 rating, mounting dimensions, wire colors, or label. Other times, a customer might require that AC Motors meet an ideal specification such as, speed, torque, and/or voltage.

Environmental Considerations
The following environmental and safety considerations must be observed during all phases of operation, service and repair of AC Motors system. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the AC Motor. Please note that even well-built AC Motors 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 an AC Motor. The atmosphere in which AC Motors are used must be conducive to good general practices of electrical/electronic equipment. Do not operate the AC Motors system in the presence of flammable gases, dust, oil, vapor or moisture. For outdoor use, AC Motors 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 AC Motors in an environment which is free from condensation, electrical noise, vibration and shock. Additionally, it is preferable to work with the AC Motors 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. Do NOT plug in or unplug when power is ON. Wait for at least 5 minutes before doing inspection work on the AC 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 AC Motors system. Plan the installation of the AC Motors 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 system’s circuitry. Failure to prevent debris from entering the AC Motors system can result in damage and/or shock.

Feedback
AC Motors have two options for feedback controls. These options are either AC Motors resolvers or AC Motors encoders. Both the AC Motors resolver and the AC Motors encoder can sense direction, speed, and the position of the output shaft. While both the AC Motors resolver and AC Motors encoder offer the same solution in multiple applications, they are greatly different. AC Motors resolvers use a second set of stator coils called the transformer to provoke rotor voltages across an air gap. Since the resolver lacks electronic components, it is very tough with a large temperature range. The AC Motors resolver is also naturally shock resistant due to how it is designed which makes it most likely used in harsh environments. The AC Motors optical encoder uses a shutter that rotates to disrupt a beam of light that crosses the air gap between a light source and the photo detector. The rotating of the shutter over time causes wear on the encoder. This wear reduces the durability and dependably of the optical encoder. The type of application being run will establish whether a resolver or an encoder is needed. AC Motors encoders are easier to implement and are more exact so they should be the primary preference for any application. A resolver should only be chosen if the durability needs and the environment in which it will be used requires it.

History
AC Induction motors have been in the industry for over 20 years now. The idea behind the AC Motors came from Nikola Telsa in the 1880’s. Nikola Telsa stated that motors do not need brushes for the rotor to commutate. He said they could be induced by a rotating magnetic field. Nikola Telsa identified the use of alternating current which induced rotating magnetic fields. Telsa filed the U.S. patent number 416,194 for his work on the AC Motor. This type of motors is what we call an AC Induction motors today. AC Motors have made a name for themselves by having a simple design, being easy to use, having a simple rugged construction and being cost effective for many different applications. Advances in technology have allowed manufacturers to build up Telsa’s idea and have allowed a great versatility in the speed control of the AC Induction Motor. From a simple phase control to more robust closed loop systems that use vector oriented field controls; AC Motors have advanced over the last one hundred and twenty years.

How Do AC Motors Work
The fundamental operation of AC Motors relies on the principles of magnetism. Simple AC Motors contain a coil of wire and two fixed magnets surrounding a shaft. When an electric (AC) charge is applied to the coil of wire, it becomes an electromagnet, generating a magnetic field. Simply described, when the magnets interact, the shaft and the coil of wires begin to rotate, operating AC motors.

How to Select AC Motors
In order to select the appropriate AC Motors for your application, first you need to determine basic specifications. Calculate the required load torque and operating speed. Remember that induction and reversible motors cannot be adjusted, they require a gearhead. If this is needed, select the appropriate gear ratio. Next determine frequency, and power supply voltage for AC motors.

Mounting
The following information is intended as a general guideline for the installation and mounting of AC Motors system. WARNING - Dangerous voltages capable of causing injury or death may be present in the AC Motors system. Use extreme caution when handling, testing, and adjusting during installation, set-up, and operation. It is very important that the wiring of AC Motors be taken into consideration upon installation and mounting. Subpanels installed inside the enclosure for mounting system components, must be a flat, rigid surface that will be free from shock, vibration, moisture, oil, vapors, or dust. Remember that the AC Motors will produce heat during work, therefore, heat dissipation should be considered in designing the system layout. Size the enclosure so as not to exceed the maximum ambient temperature rating. It is recommended that AC Motors be mounted in position as to provide adequate airflow. AC Motors should be mounted in a stable fashion, secured tightly. NOTE: There should be a minimum of 10mm between AC Motors and any other devices mounted in the system/electric panel or cabinet. NOTE: In order to comply with UL and CE requirements, the AC Motors system 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 moving part in a system, the AC Motors should be kept out of the reach of the operator. A NEMA 4X enclosure exceeds 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 recommended that the AC Motors system be protected against electrical noise interferences. Noise from signal wires can cause mechanical vibration and malfunctions.

Physical Properties
Typically, AC Motors consist of two main components: the stator and the rotor. The stator is the stationary part of AC motors, consisting of several thin laminations wound with an insulated wire, forming the core. The rotor is connected to the output shaft on the inside. The most common type of rotor used in AC Motors is the squirrel cage rotor, named after its resemblance to rodent exercise wheels. The stator mounts inside the AC motor’s enclosure, with the rotor mounted inside, and a gap separating the two from touching each other. The enclosure is the motor’s frame, containing two bearing houses.

Required Maintenance
Preventative maintenance is the key to long-lasting AC Motors. Routine inspection should be implemented. Always check AC Motors for dirt and corrosion; dirt and debris can clog air passages and reduce airflow, ultimately reducing insulation life and possible motor failure. When debris is not blatantly visible, check to ensure air flow is steady and not weak. This could potentially point towards clogging as well. In wet environments, check for corroded terminals in the conduit box and repair when necessary. Listen for excessive noise or vibration, and feel for excessive heat. This could indicate lubrication of the bearings is needed. Note: Be cautious when lubricating the bearings as excessive lubrication may lead to dirt and oils clogging air flow. Be sure to locate and remove the source of heat for AC motors to avoid system failure.

Advantages and Disadvantages
Tech Tip - AC Motors Advantages and Disadvantages The most common and simple industrial motor is the three-phase AC induction motor, sometimes shortened to AC Motor. Pertinent information can be found about AC motors by checking the nameplate. Advantages of Using AC Motors • AC Motors are of a simple design • The simple design AC motors: Simply stated, a series of three windings in the exterior stator section with a simple rotating section (rotor). The changing field caused by the 50 or 60 Hertz AC line voltage causes the AC motor rotor to rotate around the axis of the motor. • The speed of AC motors will depend upon these three variables: 1. The fixed number of winding sets (poles) built into AC motors, which determines the motors base speed. 2. The frequency of the AC line voltage. Variable speed drives change this frequency to change the speed of AC motors. 3. The amount of torque loading on AC motors, causes slipping. • AC Motors are of a low cost construction AC motors have the advantage of being the lowest cost motor. AC motors are perfect for applications requiring more than about 1/2 hp (325 watts) of power. This is due to the simple design of AC motors. For this reason, AC motors are generally preferred for fixed-speed applications, such as in industrial applications and for commercial and domestic applications where AC line power can be easily attached. Over 90% of all motors are AC induction motors. They are found in air conditioners, washers, dryers, industrial machinery, fans, blowers, vacuum cleaners, and many, many other applications. • AC Motors operate reliably The very simple design and construction of AC motors casue them to be extremely reliable and are considered to be low maintenance. Unlike DC Brush Motors, there are no brushes to replace. If AC Motors are used in the appropriate environment, protected by an enclosure, AC motors can expect to replace the bearings after several years of continuous operation. If the application is well designed in a protective environment, AC motors may not require the bearings to be replaced for more than 10 years. • Easily Found Replacements The wide use of AC motors in many different industries has resulted in easily found replacements for existing equipment repairs and/or upgrades. Many manufacturers adhere to either European (metric) or American (NEMA) standards. • AC Motors are made by many manufacturers , so it is relatively easy to obtain replacements (for basically the same motor) • AC Motors are designed in a variety of mounting styles (dependent upon the motor manufacturer). Foot Mount, C-Face, Large Flange, Vertical and Specialty. • There are many environmental styles available for AC Motors, to cover a wide range of applications and industries, called Specialty AC Motors by most. Because of the wide range of environments in which people want to use AC motors, manufacturers have adapted by providing a wide range of packaging/enclosure designs, such as Open Drip Proof (ODP), Totally Enclosed/Fan-Cooled (TEFC), Totally Enclosed/Air-Over (TEAO), Totally Enclosed/Blower-Cooled (TEBC), Totally Enclosed/Non-Ventilated (TENV), and Totally Enclosed/Water-Cooled (TEWC) versions. Disadvantages of Using AC Motors • Expensive speed control - Speed controllers can be expensive. The electronics required to handle an AC inverter driver are considerably more expensive than those required to handle a DC motor. However, if performance requirements can be met ~meaning that the required speed range is over 1/3rd of base speed ~ AC inverters and AC motors are usually more cost-effective overall, than are DC motors and DC drives. This is especially true for applications larger than 10 horsepower, because of cost savings in the AC motor. • Inability to operate at low speeds - Standard AC motors should not be operated at speeds less than about 1/3rd of the base speed, due to thermal considerations. A DC motor should be considered for these applications. • Poor positioning control - Positioning drivers and controllers can be expensive and crude. Even a vector drive is very crude when controlling a standard AC motor. Stepper motors and Servo Motors are more appropriate for applications wherein positioning and speed control is critical.

Types
The AC Motors comes in two different types known as Induction and Synchronous. These AC Motors types are determined by which rotor is used in the construction. Induction AC Motors AC Motors products can be referred to as asynchronous motors or rotating transformers. These types of AC Motors use electromagnetic induction to power the rotating device which is usually the shaft. The rotor in Induction AC Motors typically turns slower than the frequency that is supplied to it. Induced current is what causes the magnetic field that envelops the rotor of these motors. Induction AC Motors can come in one or three phases. Synchronous AC Motors The Synchronous AC Motors are typically AC Motors that have its rotor spinning at the same rate as the alternating current that is being supplied to them. The rotor can also turn at a sub multiple of the current it is supplied. Slip rings or a permanent magnet supplied with current is what generates the magnetic field around the rotor.

Where are AC Motors Used
What Industries are AC Motors used in? AC Motors are primarily used in domestic applications due to their relatively low manufacturing costs, and durability, but are also widely used in industrial applications. What Applications are AC Motors used for? AC Motors can be found in numerous home appliances and applications, including: - Clocks - Power tools - Disk drives - Washing Machines and other Home Appliances - Audio turntables - Fans They can also be found in industrial applications: - Pumps - Blowers - Conveyors - Compressors

Wiring
The following information is intended as a general guideline for wiring of Anaheim Automation AC Motors. Be aware that when you route power and signal wiring on a machine or system, radiated noise from the nearby relays, transformers, and other electronic devices can be inducted into the AC Motors and encoder signals, input/output communications, and other sensitive low voltage signals. This can cause systems faults. WARNING - Dangerous voltages capable of causing injury or death, may be present in the AC Motors system. Use extreme caution when handling, wiring, testing, and adjusting during installation, set-up, tuning, and operation. Don’t make extreme adjustments or changes to the AC Motors system parameters, which can cause mechanical vibration and result in failure and/or loss. Once the AC Motors system is wired, do not run by switching On/Off the power supply directly. Frequent power On/Off switching will cause fast aging of the system components, which will reduce the lifetime of AC Motors system. Strictly comply with the following rules: • Follow the Wiring Diagram with each AC Motor • Route high-voltage power cables separately from low-voltage power cables • Segregate input power wiring and AC Motors power cables from control wiring and motors feedback cables. 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. Allow room on the sub-panel for wire bends. • Make all cable routes as short as possible. NOTE: Factory made cables are recommended for use in our AC Motors systems. These cables are purchased separately, and are designed to minimize EMI. These cables are recommended over customer-built cables to optimize system performance and to provide additional safety for the AC Motors system and the user. WARNING - To avoid the possibility of electrical shock, perform all mounting and wiring of the AC Motors prior to applying power. Once power is applied, connection terminals may have voltage present.
