Japan developed a new type of motor magnets

According to the "Japanese economic news" reported on the 15th, Shin Etsu Chemical Industry Co., Ltd. of Japan the latest research and development of the rare earth dysprosium metal halve the amount of new high-performance 999magnett.
Dysprosium is silver rare earth metal, is the main material of air conditioning and a motor of a hybrid power vehicle in order to have the heat resistance property and in the magnet added. Air conditioner motor magnet dysprosium weight accounted for 5%, accounted for 10% in the magnet motor hybrid vehicle about. The current technology is the dysprosium and iron and Neodymium magnets mixed heating melt solidification molding, and new technology is in other material after solidification the dysprosium painted on the magnet surface, greatly reduce the usage of dysprosium. Using this technique, the air conditioner Rare earth magnets dysprosium usage can be halved.
Hitachi and Tokyo Electric Chemical Industry Corporation (TDK) and other electrical and electronic components are being developed without the use of rare earth metals and high performance motor and magnet, progress is not a. But now it seems Shin Etsu chemical company reduce rare earth metal using the amount of practical techniques for faster, the company have been conducted for this purpose billion yen investment in equipment.
