Abstract: 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.

Abstract: The disclosure relates to a method of detecting the phase-loss state of the three-phase power supply. When the phase-loss condition occurs in the input three-phase power supply of the power converter, it is determined whether the three-phase power source is in the phase-loss state through the characteristic of the frequency and amplitude variations of the ripple voltage of the DC bus, and through the sampling and the continuous detecting of the ripple voltage variations by making use of the sensor of the power converter in cooperation with the software calculation, it is determined whether the three-phase power source is in a phase-loss state. When the detected ripple voltage of the DC bus fulfills the phase-loss conditions, it is determined that the three-phase power source is in a phase-loss state.
