Abstract

The use of a low iron loss motor core is required to develop the low loss and high efficiency motor. The main material of the motor core is electrical steel sheet. Usually, the magnetic properties of the steel sheet are measured according to standard measurement methods (IEC, JIS, etc.). On the other hand, it is difficult to evaluate the characteristics of the iron core state because of the complicated shape. In this paper, we report the result of noncontact measurement of  iron loss of motor using thermal measurement method in the atmosphere.
