By changing twenty-first century, the efficiency upgrading of electrical power machinery and apparatus like transformer and motor is an important problem from the viewpoint of energy saving. The magnetic power loss of the core material of electrical power machines must decrease in order to upgrade efficiency. The efficiency upgrading of the equipment@of electrical power machines is not always possible, if high-quality magnetic material is used.
Development of the material efficient use technology is necessary for the making into low-loss design. This research technical report describes technology and result of noticing results of being necessary in order to utilize this material effectively.
Content of the report is as follows.
(1) The trend of making into low-loss of magnetic material for electric power machines.
(2) The magnetic behavior in magnetic materials of electric power machine core.
(3) Evaluation utilization measuring method of the magnetic material for electric power machines.
