Derivation of Pole Configuration in Switched Reluctance Machines

A Switched Reluctance Machine (SRM) is identified by the number of stator poles and number of rotor poles. An SRM has salient poles both on the stator and the rotor. When an electrical phase is energized with constant current, the electromagnetic torque is dependent on the relative position between the stator and rotor poles. Depending on the number of stator and rotor poles, each stator pole has a certain electrical position. The center of …
