Fault-tolerant birotor bipolar permanent magnet synchronous motor and application method thereof

The present invention discloses a fault-tolerant birotor bipolar permanent magnet synchronous motor and an application method thereof. The problem is solved that the output torque of a motor is limited in the prior art, an air gap superficial area is increased, and the torque density of the motor is further improved. The fault-tolerant birotor bipolar permanent magnet synchronous motor comprises astator and a rotor, stator slots configured to set a stator winding are uniformly distributed at the inner side and the outer side of the stator in a peripheral direction, conductors of an outer circumferential groove and an inner circumferential groove of the stator in a radial direction belong to the same phase coil, the rotor comprises an inner rotor arranged at the inner side of the stator and an outer rotor arranged at the outer side of the stator, the number of permanent magnet poles of the inner rotor is three times the number of permanent magnet poles of the outer rotor, and the permanent magnets of the inner
