A servo electric cylinder is a modular product that integrates a servo motor with a lead screw, converting the rotational motion of the servo motor into linear motion. The structure of the electric cylinder is relatively simple, mainly consisting of four major parts: the driving mechanism, the reduction unit, the linear transmission mechanism, and the frame. The types of driving motors for servo electric cylinders include DC motors, AC motors, stepper motors, and servo motors, among others.

Servo electric cylinders typically consist of a deceleration unit made up of gear reduction, worm gears, planetary gears, harmonic drives, etc. The linear transmission mechanisms of servo electric cylinders mainly include trapezoidal screws, ball screws, roller screws, sliding guideways, and so on.

The structure of standard electric cylinders is a motor-screw design, with some using synchronous belts to drive the screw and others using gears. There are many types of motors, such as brushless motors, which can be configured. When using a DC brushless motor or other servo motors to drive an encoder, the extension length of the cylinder can be controlled within a closed-loop system. Some are driven by standard motors but feature limit switches at both ends of the cylinder to control the end of the stroke. Their functions are similar to those of pneumatic cylinders. Standard electric cylinders can control feedback force, movement distance, speed, and acceleration through sensors and circuits. Specific functions depend on the configuration provided by the manufacturer.

The servo electric cylinder boasts a simple structure, minimal space requirement, and easy maintenance. It is primarily composed of an electric motor and a nut and screw mechanism, which are both simple and compact. Due to its straightforward design, it is easy to identify the cause of any faults, making routine maintenance a breeze.
