What is the difference between servo motor and ordinary motor?

Servo motor can realize precise control. Ordinary motor can turn when power is on, and stop when power is off.

1. If you only look at the shape, there is not much difference between the two shapes. However, the servo motor must also have a very complex electric control cabinet. Without this electric control cabinet, the servo motor will not rotate at all, that is, it will be normalized to a locked condition. Generally, the motor only needs a small switch box (even the switch box can be omitted).

2. The servo motor can adjust the speed arbitrarily within the rated speed according to the requirements of the computer program language in the electric control cabinet. It can be terminated at any time, run at any time, run at any place, and rotate at any speed, which is impossible for ordinary motors.

3. Servo motor is not suitable for gear reducer. The reason is that it can change the speed itself, and sometimes it is fast or slow, or the frequent positive and negative transfers lead to the impact on the transmission gear. The cost of the servo motor is expensive, and the maintenance is complicated. Generally, the motor is of high quality and low price, and the maintenance is convenient.
