This study reveals the characteristics of switched reluctance motors (SRMs) made by blanking (a) 20HX1300 of high grade low-iron-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 6.9p. 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.
