초록

A new excitation strategy for a Switched Reluctance Motor with Auxiliary Winding(SRMAW) is described and tested. The proposed scheme has auxiliary winding with one diode which is wound over all poles in one winding. In this scheme, auxiliary winding is used to reduce magnetic stress during commutations. The abrupt change of a phase excitation produces mechanical stresses resulting in vibration and noise. The acoustic noise is reduced remarkably through the 2-stage commutation. The operational principle and a characteristic comparison of the conventional SRM show that this scheme has some advantages including noise reduction as well as high drive efficiency.
