Abstract

This paper researched the loss of high speed slotless permanent magnet synchronous motor (PMSM) with appended leakage inductance structure. This PMSM adopted novel stator structure to add the leakage inductance for solving the problem that high speed slotless PMSM inductance value is small. Compared with traditional motor, this motor adopted outer slot-tooth structure in stator iron, meanwhile it would add the iron loss. Therefore, this paper adopts the Bertotti separating iron model to calculate the iron loss of the stator with outer slot-tooth, then the iron loss in the yoke of stator was compared with the outer slot-tooth. The result proved that, the outer slot-tooth structure has less influence to stator iron loss. Secondly, the influence law between the appended leakage inductance and rotor eddy loss was analyzed. The paper analyzed rotor eddy loss under the condition of three kinds of winding that has different space distribution, and obtain the influence law between the winding space distribution and rotor eddy loss.
