Motor control method

The invention provides a motor control method. The motor control method comprises the steps of obtaining current target operation parameters of a motor; comparing the value of the current target operation parameter of the motor with a preset threshold value; and according to a comparison result, determining that the current modulation mode for controlling the motor is SPWM modulation or SVPWM modulation. Based on the technical scheme of the invention, in the control program process of the motor, the modulation mode is adjusted and switched by acquiring the operation parameters corresponding to different operation control stages, so that on the premise of ensuring the operation performance of the motor, the content of harmonic waves is reduced below basic operation parameters, and the reliability of the motor is improved. Therefore, the performance of the whole controllable operation stage of the motor is improved. 本发明提供了一种电机控制方法，包括：获取电机当前的目标运行参数；将所述电机当前的目标运行参数的值与预设阈值进行比对；根据比对结果，确定当前控制所述电机的调制方式为SPWM调制或SVPWM调制。
