Experimental verification of performance of a switched reluctance motor made of permendur

This paper experimentally verifies the performance of a switched reluctance (SR) motor made of permendur. The permendur, which is an alloy created by mixing 49% cobalt with iron, has extremely high saturation flux density and very low core loss. Two types of 12/8-pole SR motors which have the same dimensions but different core material; one is conventional non-oriented Si steel and the other is permendur, are made on a trial basis to compare. As a result of experiment, the SR motor made of permendur demonstrates the better performance as compared to the conventional one in regard to torque, rotational speed, and efficiency characteristics.
