Method of balancing the rotation of a motor

摘要

A method of balancing the rotation of a motor is provided. Whether or not the motor is in a balanced rotation is determined by detecting whether the variation of a power-factor angle is less than or equal to a preset balance angle according to the principle that the load on a motor has an effect on the variation of the power-factor angle. The determined balance state of the motor is used to adjust the rotation speed of the motor.
