Synchronous control method of motor, control equipment and laser

The embodiment of the invention provides a synchronous control method of a motor, control equipment and a laser. According to the embodiment of the invention, the method comprises the steps: receiving the driving information of motors, and driving a corresponding motor in a plurality of motors at a corresponding rotating speed according to the driving information; the current rotating speed of the corresponding motor and the current rotating speed of the other motor in the coupling motor set are obtained, and the rotating speed difference value in the coupling motor set and the rotating speed difference value between the current rotating speed of the corresponding motor and the received rotating speed are determined; and rotating speed control is carried out according to the rotating speed difference value, and the controlled rotating speed is sent to the corresponding motor. Therefore, the multiple motors are synchronously controlled, and the efficiency and safety of the cooperative working process of the mu
