钕铁硼永磁材料是1983年由日本住友公司研制成的第三代稀土永磁材料,它具有很高的磁能积和高的矫顽力.由于这种材料的出现,使电工、电机行业出现了很多新的产品。使用钕铁硼永磁材料制作永磁电机就是其中之一。我国是富稀土国家,稀土蕴藏量约占全世界80％,同时,我国又是缺少钴资源的国家,所以使用稀土元素代替钴作成高性能的永磁材料,具有重要的战略意义和应用前景。沈阳工业大学唐任远教授等所开展的稀土永磁电机设计研究,取得了一系列研究成果。
NdFeB permanent magnet material is the third generation rare earth permanent magnet material developed by Sumitomo of Japan in 1983, which has high magnetic energy product and high coercive force. Due to the appearance of this material, the electrician and motor industry A lot of new products have appeared. Use of NdFeB permanent magnet material is one of the permanent magnet motor. China is a country rich in rare earths. Rare earth reserves account for about 80% of the world’s total. At the same time, our country is a country lacking cobalt resources. Therefore, using rare earth elements instead of cobalt to make high-performance permanent magnetic materials has important strategic significance and application prospect. Shenyang Polytechnic University, Professor Renyuan Tang and other rare earth permanent magnet motor designed by the research, has made a series of research results.
