Dual-motor driving system and control method thereof

The invention discloses a dual-motor driving system and a control method thereof. The dual-motor driving system comprises a driving motor I. A rotor of the driving motor I is connected with an encoder I. The encoder I is connected with an inner rotor of a magnetic gear motor I; an outer rotor of the magnetic gear motor I is connected with an encoder II; the magnetic gear motor I works in a rotating speed control mode, and the driving motor I works in a torque control mode; and the maximum rotating speed of the driving motor I is greater than Gr times of the maximum rotating speed of the output shaft of the dual-motor driving system. According to the invention, the magnetic gear motor with a dual-magnetic field modulation characteristic is used for replacing a planetary gear to realize power coupling between different motors, so that the structure of a dual-motor driving system is simplified, and the torque capability of the motor system is greatly improved on the premise of not depending ...
