The switched reluctance motor adopts a single-phase excitation mode, A, B, C, D four phases are sequentially electrified, two opposite concentrated windings after the electrification generate magnetic pull at a stator salient pole, and a rotating component is driven to rotate by using a minimum reluctance principle.
As shown in FIG. 2, in order to obtain the self-starting capability and increase the output torque of the rotating component, in the switched reluctance motor, the initial position of a stator and a rotor is the position where the tooth axis of an inner rotor is overlapped with the groove axis of an outer rotor, the phase A is selected as the initial electrified winding, when the rotating component rotates by 15 degrees, the phase B starts to be electrified, when the rotating component continues to rotate by 15 degrees, the phase C is electrified, and so on, when the phase D is electrified, the rotating component rotates by 15 degrees, then the phase A is electrified again, and the cycle is repeated.

The electricity generated by the switched reluctance motor can be directly transmitted to the disc type motor without passing through the storage battery 25, and meanwhile, the electricity generated by the disc type motor can be directly transmitted to the switched reluctance motor without passing through the storage battery 25, namely, the storage battery does not participate in the work, so that the stepless speed change mode of the double-rotor motor can be realized, and the same effect as that of a stepless speed changer can be achieved.
The working mode of the switched reluctance-disc type double-rotor motor of the hybrid electric vehicle under different working conditions is as follows:
an electric starting mode: in the mode, the engine is turned off, the storage battery 25 supplies power to the disc type motor winding 14 and the switched reluctance motor winding 4, the outer rotor rotates, the first rotor 5 drives the engine 24 to rotate, the ignition system is started, and the engine 24 starts to run after the rotation speed of the engine 24 reaches the ignition threshold value.

Climbing mode: the mode is suitable for the working condition of low speed and heavy load of the vehicle, the required rotating speed of the vehicle is lower than the rotating speed of the engine 24, the required torque is higher than the torque of the engine 24, the power output by the engine 24 is transmitted in two paths, one part is transmitted to the wheels 27 through the first rotor 5, the air gap and the outer rotor, and the other part stores the power into the storage battery 25 through the winding. At this time, the battery 25 receives power from the engine 24 and supplies power to the disc motor winding 14, and the switched reluctance motor operates in a power generation state and the disc motor operates in an electric state.
High-speed mode: this mode is suitable for a high speed and light load condition of the vehicle, the required speed of the vehicle is higher than the speed of the engine 24, the required torque is lower than the torque of the engine 24, the power output by the engine 24 is transmitted to the wheels 27 through the first rotor 5, the air gap and the outer rotor, and the storage battery 25 simultaneously receives the power from the disc type motor winding 14 and provides the power to the switched reluctance motor winding 4.
