An electric cylinder consists of the following main parts:
Motor: A servo motor or stepper motor is typically used to power the cylinder. Servomotors offer high precision, high speed, and high responsiveness, and can control the cylinder's position and speed. Stepper motors have a simpler structure and lower cost, making them suitable for applications where precision is less critical.
Transmission: Common transmission methods include ball screws and synchronous belts. Ball screws offer high efficiency, high precision, and long life, enabling high-precision linear motion. Synchronous belts offer smooth transmission, low noise, and easy maintenance, making them suitable for high-speed applications.
Guide: Linear guides or ball screws are typically used as guides to ensure the linearity and stability of the cylinder's motion. Linear guides offer low friction, high precision, and high load capacity, while ball screws offer high efficiency, high precision, and excellent rigidity.
Casing: The cylinder's casing protects the internal structure and supports and secures the cylinder. It is typically made of high-strength materials such as aluminum alloy or cast iron, offering excellent rigidity and corrosion resistance.
Control System: The electric cylinder's control system is its core component, responsible for controlling the motor's motion, implementing various motion modes, and position control. This control system typically includes a driver, controller, and programming software, communicating with a host computer or PLC to achieve automated control of the electric cylinder.
In addition, electric cylinders may also include auxiliary components such as encoders, limit switches, and anti-collision devices to enhance precision, safety, and reliability.
