Development of high‐efficiency switched reluctance motor

In this paper, several techniques of the efficiency improvement of SRM drives are described. One of these improvements is the optimization of applied voltage waveform. Drive efficiency is further increased by application of new low-iron-loss materials such as Super E-Core brand steel strip. Another step of the efficiency improvement consists in optimization of components incurring iron and copper losses by using computer program PC-SRD. As a result, the highest efficiency level achieved in the study was 94.3%. © 2007 Wiley Periodicals, Inc.
