电机的附加损耗计算是个十分复杂的交变电磁场问题,它的源和场与众多计因子有关。多年来一直沿用传统方法计算,成为改进大型水轮发电机设计的难关。定子附加损耗不但影响电机效率,还会引起电机局部发热,严重影响电机可靠运行。当今世界著名厂家都在竭力改革,非常重视这项课题。为了攻克这项难关,为三峡巨型水轮发电机设计开路,哈尔滨大电机研究 The additional loss calculation of a motor is a very complex alternating electromagnetic field problem, its source and field are related to many factors. Over the years has been used in traditional methods of calculation, a large hydro turbine to improve the design of the difficulties. Stator additional loss not only affects the motor efficiency, but also cause the motor to heat locally, seriously affecting the reliable operation of the motor. Today’s world-renowned manufacturers are trying their best to reform, attaches great importance to this issue. In order to overcome this difficulty, design for the Three Gorges giant hydro-generator open, Harbin large motor research
