【摘要】 目前永磁同步电动机的设计和使用中存在的一个突出问题是永磁材料的价格昂贵。文中在编制了3KW、4极钕铁硼永磁同步电动机磁路设计电算程序的基础上,采用复合形法对磁钢尺寸进行优化。该方法具有优化快速、可靠、程序简单、实用性强的特点。结果表明,电机经优化设计后,不但所用永磁体的尺寸大大减少,其运行特性曲线还具有高效率、高功率因数的优良品质。更多还原

【Abstract】 In view of the high cost of NdFeB permanent magnet material, an electromagnet calculation program is worked out and the design is optimied with complex method to decrease the dimensions of the magnet steel. Taking a 3KW、4 poles motor as an example, the results show that the designed motor with high efficiency and power factor attains the optimal goal.更多还原
