The invention relates to the technical field of motor control, and provides a motor control method and device. The method comprises the steps of obtaining a current rotation angle difference according to a current rotation angle of a transmission part in a transmission mechanism and a target rotation angle of the transmission part moving to a mechanical zero position of a cam in the transmission mechanism; according to the current rotation angle difference, the motor is controlled to drive the transmission part to move until the current rotation angle difference is within a preset interval; and determining that the current rotation angle difference is in a preset interval, and controlling the motor to generate a zero signal. According to the motor control method provided by the embodiment of the invention, the motor can be accurately controlled to drive the transmission part to move to the corresponding position of the cam, and the accuracy of driving mode switching is improved.
