The operation analysis and efficiency improvement of switched reluctance motors with high silicon steel

In this paper, the efficiency improvements of SRM drive are reported by the waveform optimization of applied voltage and employing high silicon steel called Super E-Core. It is shown that efficiency is improved up to 94.0% at a speed of 8000 r/min and with an output of 2.7 kW. In addition, a comparison of a test machine with conventional low iron loss silicon steel of 35A300 is shown.
