摘要:
提出双层 Halbach 永磁电机的二维解析模型,模型中转子永磁包括内外两层,每层每极均 由两块永磁构成,且每层中间磁块均为径向磁化。通过分区域求解标量磁位的微分方程,解析得到 双层 Halbach 无槽电机的气隙磁场。利用卡特系数考虑齿槽作用,解析获得双层 Halbach 有槽电机 的气隙磁场。接着,为优化气隙磁场波形,分别解析获得外层径向磁化磁块的最优极弧比和内层径 向磁化磁块的最优极弧比,从而获得双层 Halbach 电机气隙磁场的优化解。计算结果表明,双层 Halbach 电机不仅气隙磁场和反电势的波形正弦度都优于单层 Halbach 电机,而且电磁转矩的波动 更小,因此具有更好的电磁性能。二维有限元法与二维解析法计算结果一致性较好,验证了二维解 析模型的正确性。
Abstract:
A 2-dimensional ( 2D) analitycal model of a permanent magnet ( PM) motor with twolayer Halbach was proposed. In the model, there is two-piece Halbach array and a radially magnetized magnet piece for every pole of each layer. The air-gap magnetic fields in the slotless twolayer Halbach motor were analytically obtained by solving the differential equations with magnetic scalar potential. The slot effect was considered by a Carter’s factor,and the air-gap magnetic fields in the slotted twolayer Halbach motor were derived. The optimal pole-arc ratio of the radially magnetized magnet piece were separately analytically gained for each layer and the air-gap magnetic fields were analytically optimized for the twolayer Halbach motor. The predicted results show that the twolayer Halbach motor exhibits a higher sine degree of both the air-gap magnetic field and the back electromotive force than the singlelayer one, thus improving the electromagnetic performance. A 2D finite element method is employed to confirm the 2D analytical model.?
