This paper describes about the core loss (magnetic power loss, iron loss) reduction method for upgrading high efficiency motor. It is difficult to achieve the core loss reduction of motor by using conventional technique. Therefore we proposed the vector magnetic characteristic technology which is constructed magnetic characteristic analytical method, evaluation method of magnetic materials, and the building factor problem. Furthermore as an important magnetic characteristic, magnetostriction phenomena based on new viewpoint are introduced and its numerical simulation results.
