The magnetic field will drive the rotor to rotate an angle, so that the direction of magnetic fields of the rotor is consistent with that of the stator. https://www.123articleonline.com/articles/1276864/how-to-control-speed-of-servo-motor-anti-interference-measures A servomotor refers to the actuator to control the operation of mechanical components in the servo system and is a subsidy motor indirect transmission device. The servo motor can control speed, whose position accuracy is high, and convert voltage signal into torque and speed to drive the controlled object. A servomotor speed is controlled by the input signal, responding quickly. In an automatic control system, it is used as an executive component, and has the characteristics of a small electromechanical time constant, high linearity, starting voltage. Besides, it can convert the received electrical signal into the angular displacement or angular velocity output on the motor shaft. https://www.123articleonline.com/articles/1279842/how-to-fix-a-refrigerator-compressor The refrigerator compressor is the core of a refrigerator and achieves the cooling effect. Due to the frequent use of the refrigerator, the refrigerator compressor will inevitably occur faults.
