Background

The stator and the rotor of the switched reluctance motor are both in a salient pole structure, and the stator winding is a concentrated winding and can run without being electrified like a common motor. Since the power needs to be supplied according to the relative position of the stator and the rotor, the power needs to be used together with a controller. At present, normally used switched reluctance motors are all placed near the motors and are connected with the motors and the controller through power lines. A plurality of power lines are needed between the normal controller and the motor, so that the cost is increased, and meanwhile, the installation position and the wiring condition of the controller are also needed to be considered, so that the installation process becomes complicated, and the whole layout needs to be planned. The controller also needs a separate shell for sealing, heat dissipation and the like, which increases the cost to a great extent. In summary, a safe and reliable switched reluctance motor structure that the controller can be connected with the motor without a power line and a separate shell is not needed for the controller is yet to be invented.
