永磁同步电机偏心磁极优化设计
Optimal design of eccentric magnet pole for permanent-magnet synchronous motors
摘要
Abstract
In order to optimize the air⁃gap flux density, the surface⁃mounted eccentric magnet pole of a permanent magnet synchronous motor was designed. The air⁃gap flux density of the eccentric magnet pole was studied utilizing an analytic method. The influence of the offset on the waveform of air⁃gap flux density and the motor performance was systematically analyzed. The expression of air⁃gap flux density with offset in parallel magnetization or radial magnetization was detailed, proposing a novel optimal design method for the eccentric magnet pole with analytical expression in a polar arc range. The validity of the proposed method was verified by finite element analysis as well as the optimal design of an 180kW prototype of the permanent magnet motor, proving the correctness and effective⁃ness of the calculation. The result shows that the best offset of using an analytic method was similar to that of the fi⁃nite element method (FEM).关键词
