Experimental Evaluation of Characteristic of Switched Reluctance Motor Made by Blanking Amorphous Alloy Foil

This paper provides the characteristics of switched reluctance motors (SRMs) made by blanking (a) 20H1300 of high grade low-iron-loss silicon steel (0.20mm thickness) and (b) 2605SA1 of amorphous alloy (0.025mm thickness). As first prototype, 70W-SRM (40mm thickness) is manufactured by blanking 1600 sheets of amorphous alloy and adhesively laminating them. In experiment, the motor efficiency of amorphous-alloy-SRM is improved by 6.4p.t. compared with that of silicon-steel-SRM. In addition, the iron loss of amorphous-alloy-SRM is reduced by 61.9% compared with that of silicon-steel-SRM.
