Switched reluctance motor structure

The stator and rotor of switched reluctance motor are both salient pole structures, that is, double salient pole structures. The number of poles of rotor and stator is not equal. The rotor and stator cores are made of silicon steel sheets with good magnetic permeability, the rotor core has no windings, and the stator salient pole has concentrated windings. (1) The stator core of reluctance motor has six tooth poles, which are formed by stamping and stacking silicon steel sheets with good magnetic permeability; (2) The rotor core of the reluctance motor has four tooth poles, which are formed by stamping and stacking silicon steel sheets with good magnetic permeability. Like ordinary motors, there is a small gap between the rotor and the stator, and the rotor can rotate freely in the stator. Because both stator and rotor have salient poles, this form is also called double salient pole structure. (3) The stator teeth are wound with coils, which are excitation windings that provide working magnetic fields for the motor. (4) The stator and rotor of switched reluctance motor are made of silicon steel sheets. The rotor has neither coil winding nor permanent magnet, and the salient pole of the stator is provided with coil winding. ⑤ When the coil on the stator is energized, it will attract the salient pole of the rotor to rotate. Under the control of the switching device, the coils are energized in turn and the rotor will continue to rotate.
