摘　　要：基于普通的径向磁悬浮轴承 ,研究定子绕组由产生旋转偏磁磁场的绕组和产生旋转控制磁场的绕组叠加的动力磁悬浮轴承的工作原理。在两种绕组的极数相差 2极时 ,动力磁悬浮轴承除产生支承转子的径向轴承力外 。Based on the principle of radial magnetic bearing,it is presented for stator winding using a combination of the winding produces rotary biased magnetic field and the winding produces rotary control magnetic field.When pole pair number difference is equal to two,the proposed stator of the power magnetic bearing(P MB)has two kinds of winding:one is for levitation control and another is for rotation.P MB also produces the motoring torque,in addition to radial force.

关 键 词：动力磁悬浮轴承 气隙旋转磁场 电磁力 工作原理
