Electric Cylinder

Electric Cylinder is an electromechanical integrated actuator that converts the rotational motion of a servo motor or stepper motor into linear motion through a mechanical transmission mechanism (usually a ball screw or trapezoidal screw), which can be regarded as an "electrified hydraulic cylinder" or a "high-precision electric push rod".

Mainly used to implement the pushing, lifting, extending, or positioning actions of loads. It combines the power output of the motor with the motion conversion function of the screw, the high precision of servo control, and the linear driving ability of traditional cylinders. Electric Cylinder is a widely used electric alternative to traditional hydraulic cylinders and cylinders in automation equipment, industrial machinery, and precision positioning systems.

Working Principle of Electric Cylinder

An electric cylinder converts electric motor power into straight-line mechanical motion. First, servo or brushless motors output rotary power. Then, internal ball screw or lead screw structures convert rotation into linear thrust. Thus, the electric cylinder mover achieves programmable linear displacement. Unlike pneumatic and hydraulic cylinders, this all-electric structure eliminates fluid medium reliance. It also delivers stable, adjustable motion output for automated equipment.

Core Technical Advantages of Electric Cylinder

Electric cylinder features high positioning accuracy and flexible motion control. Meanwhile, the integrated electric cylinder actuator supports adjustable speed and acceleration. Besides, the sealed electric cylinder structure adapts to clean and harsh workshop environments. Furthermore, the modular electric cylinder module enables fast equipment integration. It also runs with low vibration and zero fluid leakage pollution.

Industrial Application Case of Electric Cylinder

A 3C electronic automation line adopts servo electric cylinder for component pressing. The electric cylinder stage maintains consistent micron-level positioning stability. It supports frequent reciprocating motion for 24-hour continuous operation. In addition, the electric cylinder motion controller realizes real-time position correction. This application fully stabilizes automated precision assembly procedures.

FAQ: 

1. Which brands of servo motors are compatible with linear electric cylinder?
There are no brand restrictions, and mainstream brands such as Huichuan, Delta, Panasonic, Mitsubishi, Yaskawa, Siemens, and Colmorgen are compatible. Only the motor base number, flange, and shaft diameter need to be matched.

2.What are the connection methods between screw type electric cylinder and servo motors?
Direct connection (motor shaft and screw shaft coaxial), coupling connection (elastic coupling/plum blossom coupling), and folding connection are synchronous belt/gear connections, all of which need to ensure coaxiality.

3.What is the matching principle between the motor base number and the cylinder diameter of electric cylinder?
Micro cylinder (Φ 16-25) with 40/60 base motor; Small cylinder (Φ 32-50) with 60/80 base motor; Medium sized cylinder (Φ 63-80) with 80/90 base motor; Heavy duty cylinders (over Φ 100) are equipped with 110/130/180 base motors.

4. Is it necessary to add a brake when matching servo motors?
Vertical load conditions (such as lifting and hoisting) must be added  to prevent power outages and falling objects; Horizontal load conditions can be adjusted according to demand and adapted to power outage positioning requirements.

5. What are the precautions for matching servo motors with high-speed electric cylinder?
Choose a high-speed servo motor (above 3000r/min) and pair it with a large lead screw to check the matching between the motor inertia and the electric cylinder inertia to avoid start stop impact.
