Then a vector control method with speed closed-loop and magnetic linkage closed loops put forward, which is based on the constant velocity by means of stator flux-oriented vector control.
To keep leakage flux to be constant, the relation is analyzed between the air gap length and the non-magnetic material thickness with the rare earth magnet thickness under the air gap length variety.
在气隙长度发生变化时，为了保证漏磁大小不变，讨论了气隙与非导磁衬套厚度、磁钢厚度的关系。

Machine magnetic parameters influence the control performance of an interior permanent magnet (PM) machine, in both the constant torque and the flux-weakening operating regions.
