Working principle of servo motor (how servo motor works)

The rotor inside the servo motor is a permanent magnet. The U / V / W three-phase electricity controlled by the driver forms an electromagnetic field. The rotor rotates under the effect of this magnetic field. At the same time, the encoder of the motor feeds back the signal to the driver. The driver adjusts the rotation angle of the rotor according to the comparison between the feedback value and the target value. The accuracy of servo motor depends on the accuracy of encoder (number of lines).

Observe the voltmeter and ammeter when starting. When the small-scale refrigeration and air-conditioning equipment does not have an ammeter or electric meter, a multimeter or electric pen can be used to check the power supply.
