提出了一种新型的无轴承电机绕组结构，用于产生径向力。在定子槽中不需要额外的悬浮力绕组。所有导体都可同时有效地用于产生电机扭矩和悬浮力。原始电机线圈并联连接，但是，这些线圈从悬架逆变器端子串联差分连接。因此，由于转子旋转引起的速度感应电压被消除，从而如具有分离的差动悬浮绕组的常规无轴承电动机的情况那样，悬浮端子电压被降低。已开发的测试机和测试结果。
A novel winding structure of bearingless motors has been proposed for radial force generation. Additional suspension force windings are not needed in stator slots. All conductors are effectively used for both motor torque and suspension force generations, simultaneously. Original motor coils are connected in parallel, however, these are differentially connected in series from the suspension inverter terminals. Thus, speed induced voltage caused by rotor rotation is cancelled so that suspension terminal voltage is reduced as in the case of conventional bearingless motors with separated differential suspension winding. A test machine has been developed and test results are presented.
