In this paper, the iron loss of an actual stator core of the complex configuration was evaluated by using the proposed effective magnetic path length and the excitation inner core, which were developed in this research. The iron loss of an actual stator core in the manufacturing process was described. Iron losses of actual stator cores before and after the varnish processing were measured using the excitation inner core of several kinds of shapes. As a result, iron losses of actual stator cores evaluated using the proposed effective magnetic path length were within appropriate values.

The specimens after heat treatment were set into the vibration sample magnetometer and the hysteresis loops and the Curie point temperature were measured. It can be shown that temperature as was expected has a significant influence on the magnetic and a shape memory property of investigated material.
