What is a linear actuator?
A linear actuator is an electromechanical device which translates rotary motion from a motor into linear displacement.
What are linear actuators used for? Which linear actuator is best for my project?
- Belt-driven linear actuators are designed for high-speeds and light loads, and are suitable only for low-inertial loads. Common applications for belt actuators include automated windows and doors, high-speed data acquisition, and scanning devices.
- Screw-driven linear actuators are suitable for low-speeds, heavy loads, and high-inertial loads. These devices are typically used in positioning equipment, CNC machines, and anywhere else slow point-to-point movement is required.
- Rod-style linear actuators excel at lifting and thrusting applications, with thrust-bearings built into the actuators themselves. They are similar to screw-driven tables in terms of speed, load, positioning, and accuracy capabilities. Rod actuators offer a compact, collapsible design great for projects where space constraints are a concern.
- Linear servos are capable of bearing heavy loads at a wide range of speeds (1 to 3,000 mm/sec) and are able to handle high-inertial loads while delivering accurate force. Linear servos are typically used in high-precision, heavy-load and high-inertial load applications, as well as in precision-torque and positioning applications.
- Stepper Linear Actuators are intended for point-to-point positioning applications. This type of actuator is best suited for applications with light loads and slow speeds. Steppers are open loop accurate, so they do not require an encoder for accurate positioning.
- Brushless DC Linear Actuators are great for high-speed motion. Their specialty is delivering power at high speeds, rather than the high accuracy of a stepper. Brushless linear actuators may require an encoder to obtain accurate positioning data.
