A linear actuator is an actuator that creates motion in a straight line. Typically a rotary motor is used as the source of actuation in conjunction with a lead or ball screw to create the linear motion. The motors can be either brushed or brushless. Often a feedback device is built into the actuator to allow for position control.
- Since screws are used to create the linear motion, linear actuators are capable of producing large amounts of force in a small package
ADVANCED Motion Controls' Capabilities
- Rotary motors are the source of motion and setting up a linear actuator is just like setting up a standard motor
- Linear actuators with potentiometer feedback are one of the few applications where analog drives can close the position loop without an external controller, creating a cost-effective and easy-to-setup system
