Abstract :
A new excitation strategy for a switched reluctance motor with auxiliary winding (SRMAW) is described and tested. This scheme has an auxiliary winding with one diode which is wound to all the poles in one winding. In this scheme, the auxiliary winding is used to reduce magnetic stress during commutations. The abrupt change of a phase excitation produces mechanical stresses and it results in vibration and noise. The acoustic noise is reduced through 2-stage commutation. The operational principle and a characteristic comparison to that of the conventional SRM show that this scheme has some advantages including noise reduction as well as high efficiency drive
