摘　　要：抽油机常常由三相异步电动机驱动,由于抽油机电机负荷率很低,造成电机效率低,功率因数低,电能浪费大。结合近几年来作者研制的成功用于抽油机电机节能的稀土永磁同步电动机,介绍了钕、铁、硼等稀土材料的特性、稀土永磁电机和自起动稀土永磁电机在抽油机上的应用。Three phase asynchronous motors are often used to drive oil - pumping units. Operating at a very low load factor are running at low efficiencies and low power factors with a lot of energy wasted. Over the past years the Rare Earth Permanent Magnet (REPM)synchronous motors developed by the authors found a successful application in the field of motor energy — saving in oil — pumping units. In the paper introduced are rare earth materials such as NdFeB,REPM Motors and the application of self - started REPM synchronous motors in oil - pumping units.
