Switched reluctance motor SR for short, is a special type of synchronous motor, the stator and rotor are doubly salient structure, strong brushless, large output torque.
Because the coil winding of the switched reluctance motor only needs a unidirectional current, it only needs a unipolar power converter to supply power, so its circuit structure is very simple.
The early switched reluctance motor speed control system uses position sensor to detect the rotor position, and now the switched reluctance motor speed control system without position sensor has appeared.
