【摘要】：为简化和统一复杂绕组磁场的分析问题,提出一种简易的单匝线圈磁场预测绕组磁场计算方法。基于高速永磁同步电机等效同心圆多层模型和涡流场泊松方程,结合各种介质交界面条件和边界条件,建立了稀疏矩阵形式的单匝线圈电枢磁场的解析方程组。从绕组排布组合形式多样性的特点出发,根据线圈位置和同相线圈连接方式,通过线圈代数化和绕组集合化处理,将线圈和绕组之间的递推关系简化和统一,揭示其关联性。线圈和绕组电枢磁场的解析计算方法和内部关系得到有限元仿真和相关文献计算方法的证实,结果表明了使用单匝线圈磁场研究绕组磁场问题的准确性和可行性。最后基于相关计算方法和内部关系的研究,分析了绕组合成磁场时空谐波的规律。
[Abstract]:In order to simplify and unify the analysis of complex winding magnetic field, a simple calculation method for predicting winding magnetic field is presented.Based on the equivalent concentric circle multilayer model of high speed permanent magnet synchronous motor and the Poisson equation of eddy current field, the analytical equations of the armature magnetic field in the form of sparse matrix are established by combining the interface conditions and boundary conditions of various media.Based on the diversity of winding arrangement and combination, according to the position of coils and the connection mode of in-phase coils, the recursion relationship between coils and windings is simplified and unified by means of algebraic winding and collectivization of windings, which reveals the correlation between coils and windings.The analytical calculation method and internal relation of the magnetic field of coil and winding armature are verified by finite element simulation and related literature calculation method. The results show the accuracy and feasibility of using single-turn coil magnetic field to study winding magnetic field problem.Finally, based on the research of correlation calculation method and internal relation, the law of synthetic magnetic field space-time harmonics in windings is analyzed.
