悬浮双圆锥形永磁同步转子所需的径向力和浮力是由转子磁场和两个具有一个极对差的定子磁场叠加而成的。由于气隙中磁场的叠加，一些力的干扰会干扰悬浮驱动器。这些扰动的起源解释和描述在一个简化的模型。的扰动的幅度进行计算，并从一个建成的原型获得的测量值进行比较。结果表明，当定子驱动磁场小于转子磁场时，干扰不会影响驱动器的稳定性。
The radial and lévitation forces, necessary to suspend a double conical permanent magnet synchronous rotor, are generated by superposition of the rotor field and two stator fields with one pole pair difference. Due to the superposition of the fields in the air gap, some force interferences are disturbing the levitated drive. The origin of these perturbations are explained and described in a simplified model. The amplitude of the perturbations are calculated and compared to measurements obtained from a built prototype. It is shown that, when the stator driving field is small compared to the rotor field, the interferences don't compromise the stability of the drive.
