Principle of Electric Actuator

Linear Actuator, also known as push rod motor, electric cylinder and linear actuator. The Linear Actuator is a kind of electric drive device that converts the rotating motion of the motor into the linear reciprocating motion of the push rod. It can be used as an execution machine in a variety of simple or complex process flows to achieve remote control, centralized control or automatic control. This article will take you through how a Linear Actuator works.

Because of the novel and exquisite design, small size, high precision, complete synchronization, good self-locking performance and other characteristics, Linear Actuator is widely used in various industries, such as electric medical bed, electric sofa, electric booth lifting rod, industrial electric lifting system and so on.

The main structure of the Linear Actuator is composed of a drive motor, a reduction gear, a screw, a nut, a guide sleeve, a push rod, a slide seat, a spring, a shell, a turbine, and a micro-motion control switch.

The design of linear actuators is influenced by several factors such as load capacity, speed, travel distance, input voltage and control options. Manufacturers produce different types of linear actuators to meet the various needs of industrial automation.

Working principle

After the motor is decelerated by a gear, it drives a pair of screw nuts. The rotary motion of the motor is changed into linear motion, and the push rod action is completed by the positive and negative rotation of the motor. For example, through various levers, rockers or connecting rods and other mechanisms can complete rotation, shaking and other complex actions. By changing the lever lever lever length, you can increase or increase the stroke.
