变频永磁同步电机（螺杆压缩机用）
刚开始做螺杆压缩机永磁同步电机，下面计算单是一台45kW、8极、3000rmp、功率系数1.2，效率需达到1级能效标准。我现在对计算单里面的计算数据是否合理弄不清楚（工程经验少）比如：齿磁密、反电势、电枢电密、热负荷等重要参数的值，希望大神指导指导。DJUSTABLE-SPEED PERMANENT MAGNET SYNCHRONOUS MOTOR DESIGN

大神给指导指导，这东西没老师带真的难摸啊！！ Rotor-Yoke Flux Density (Tesla):0.340537转子轭磁密有点底，Cogging Torque (N.m): 14.674相对于额定转矩143.212，齿槽转矩有点太大了。你这程序怎么连最重要的东西空载反电势都没有显示呢？ Nephology 发表于 2016-6-29 13:56

就是ANSOFT V14的RM啊，FULL-LOAD反电动势是482V啊！您说的上面的转子轭磁密底，和齿槽转矩大怎么解决呢？需要调哪些参数

我说的是空载反电势，你那个482V是满负载时的反电势。轭部磁密磁密太小了可以调节一下转子的内径，齿槽转矩太大了可以通过改变极弧系数，改变永磁体形状，改变定子斜槽虚拟槽等等 “Maximum Line Induced Voltage (V): 482.951”， 字面上可以译成“最大线感应电压”，实际上是否就是空载反电势？因为是“Maximun”？请赐教。 除以1.414你这个最大也就340 实际测试还会有偏差设计值做到365左右 楼主，我的设计表中也没有空载反电势这一个参数，请问应该在哪里找出呢？
