Linear actuators typically have built-in motors to drive the piston for linear motion.
1. Linear Actuator Structure and Types
A linear actuator is a device that achieves linear motion through a drive mechanism. It consists of a motor, a reducer, a guide rail, a slider, and a piston. Depending on their operating method, linear actuators can be categorized as lead screw, gear, or hydraulic.
2. Working Principle of a Linear Actuator
A linear actuator's motion is driven by a motor driving the piston for linear motion. The motor provides the driving force, while the reducer generates high torque and low speed output. The linear actuator uses guide rails and sliders to drive the piston for linear motion. When the motor is engaged at one end and released at the other, the piston moves linearly along the guide rail.
3. Linear Actuator Motor
Linear actuators typically have built-in motors to drive the piston for linear motion. When selecting a motor, consider parameters such as motor output power, output speed, output torque, and rated voltage. Depending on the application, motors can be categorized as AC or DC motors. Some linear actuators also have built-in stepper motors.
