servo motor It is a motor that can rotate with high precision. Electric signals can be converted into torque and speed to drive and control objects, so servo motors can also be called executive motors. Usually, this type of motor consists of a control circuit that provides feedback on the current position of the motor shaft, enabling the servo motor to rotate with high precision. If you want to rotate an object at a specific angle or distance, use a servo motor.

There are classifications for motors, and of course, there are also classifications for servo motors,It is divided into DC servo motor and AC servo motorAmong themDC servo motors are divided into brushed motors and brushless motorsAndAC servo motors themselves are brushless motors, so they are divided into synchronous motors and asynchronous motors.

DC servo motors are divided into brushed motors and brushless motors. Brushed motors have low cost, simple structure, large starting torque, wide speed range, and easy control. But its drawbacks are quite obvious, it is very inconvenient to maintain and has great environmental requirements.

Brushless motors have small size, light weight, high output, fast response, high speed, low inertia, smooth rotation, and stable torque. The control is complex and easy to achieve intelligence. Its electronic commutation method is flexible and can be square wave commutation or sine wave commutation. The motor is maintenance free, highly efficient, operates at low temperatures, emits minimal electromagnetic radiation, has a long lifespan, and can be used in various environments. But the disadvantage of high cost makes it very awkward, especially in high magnetic field environments where it is easy to lose its effectiveness.

The communication servo motor itself is a brushless motor, and its internal rotor is a permanent magnet, which is also one of the difficulties in manufacturing servo motors in China.AC servo motors are divided into synchronous motors and asynchronous motors. Synchronous motors have a wide power range, but they have obvious disadvantages, such as low maximum speed, which rapidly decreases with increasing power. Therefore, they are generally used in low-speed smooth operation. Asynchronous motors have high power, strong heat dissipation, and can operate at high speed for a long time, but their disadvantage is instability.
