Linear actuators are an integral part of the field of automation control, and they are widely used in various machines and equipment to achieve accurate position control and speed control.
The principle of linear actuator
A linear actuator is a mechanism that converts electrical signals into linear motion. Their working principle is based on the basic principle of electromagnetic field, which converts the rotational motion of the motor into linear motion through electromagnetic force or motor. Linear actuators can accurately control the speed, position and direction of motion, enabling high-precision position control and speed control.
Classification of linear actuators
Electric linear actuator: The electric linear actuator converts rotary motion into linear motion through the rotation of the motor. The advantages of this kind of actuator are high precision and fast response, but it requires a lot of power.
Pneumatic linear actuator: Pneumatic linear actuator uses compressed air to push the piston or the piston in the cylinder to move in a straight line. The advantages of this type of actuator are fast speed and high thrust, but the accuracy is slightly lower.
Hydraulic linear actuator: The hydraulic linear actuator uses hydraulic oil to transmit pressure to push the piston or the piston in the hydraulic cylinder to move, thereby realizing linear motion. The advantages of this kind of actuator are large thrust and high precision, but it requires high working pressure.
Application of linear actuator
Linear actuators are widely used in various fields, such as:
Industrial automation: In production lines and processing machinery, linear actuators can accurately control the position and speed of workpieces, thereby improving production efficiency and product quality.
Robotic system: In a robotic system, linear actuators can realize the degree of freedom and motion of the robot, thereby improving the flexibility and precision of the robot.
Transportation field: In urban transportation systems such as subways and light rails, linear actuators can accurately control the position and speed of vehicles, thereby improving the efficiency and safety of the transportation system.
