“…It was confirmed that the accuracy of FEA is low in the simple iron loss calculation algorithm based on the iron loss curve [31]. This is because the analysis based on the iron loss curve is not applicable into the complicated magnetic flux waveforms of the SRM.…”

“…In addition, the same designed SRM is manufactured by blanking silicon steel for comparative verification. Note that this paper is the updated version of the conference paper [31]. The manuscript additionally evaluates the B-H characteristics and iron loss characteristics with ring cores, improves the accuracy of finite element analysis (FEA), and replaces all the old experimental results of 7200r/min with the new experimental results of 10000r/min.…”

This study reveals the characteristics of switched reluctance motors (SRMs) made by blanking (a) 20HX1300 of high grade lowiron-loss silicon steel (0.20mm thickness) and (b) 2605SA1 of amorphous alloy (0.025mm thickness). The blanking of the amorphous alloy is an innovative technology for the mass production of the high efficiency amorphous-alloy-motor. The impact of the processing methods on the magnetic properties are evaluated using the ring cores processed by the following methods: the wire cutting and the blanking. On the other hand, the experiment with the SRMs processed by the blanking evaluates the characteristics depending on the material. As first prototype, 70W-SRM (40mm thickness) is manufactured by blanking 1600 sheets of the amorphous alloy and adhesively laminating them. In the experiment, the motor efficiency of the amorphous-alloy-SRM is improved by 6.9 p.t. compared with that of silicon-steel-SRM. In addition, the iron loss of amorphous-alloy-SRM is reduced by 78.7% compared with that of silicon-steel-SRM.
