Abstract :
The aligned to unaligned phase inductance ratio and the number of stator and rotor poles strongly affect the resolution of indirect rotor position sensing methods for switched reluctance motor (SRM) drives. A higher inductance ratio increases the resolution, while higher number of phases increases the available sampling window for indirect position sensing. However, these requirements are conflicting design criteria for an SRM. In this paper, the design considerations and trade-offs for sensorless SRM drives are analyzed by computer simulations. The existing indirect position sensing methods and their applicability for various SRM drives are also discussed
