Outline of Final Research Achievements

This research reports new induction heating technique to control stress vector magnetic property of motor core materials for developing high efficiency motor. At first a new heating coil, which is used cylindrical magnetic flux concentration plate is made by using in order to heat the local part of the motor core. Next, the motor cores are heated by using the new developed heating coil. In addition the magnetic properties of the heated motor core is measured. As these results, it is possible to decrease the magnetic power loss about 40 % of the motor core by using the induction heating.
