摘要/Abstract

摘要： 针对空心杯电机绕组轴向分布不均匀,需要进行三维磁场计算电机性能,导致耗时较长的问题。本文提出一种二维磁链半解析模型。通过二维有限元计算气隙磁密并结合电机的绕组因数和端部漏磁系数,构建磁链半解析模型。基于所提出的半解析模型对一台2极6槽电机进行设计,验证该方法的有效性。研究结果表明,半解析模型计算时间相比三维有限元计算减少近120倍,误差在2%以内,和实验结果相比误差小于5%,为空心杯电机设计和优化提供参考。

Abstract:

In response to the uneven axial distribution of the windings in hollow cup motor,three-dimensional magnetic field calculations for motor performance are often required, which leads to a relatively long time consumption. This paper proposes a two-dimensional magnetic linkage semi-analytical model. A semi-analytical model is constructed by using twodimensional finite elements to calculate air gap magnetic density and combining the winding factor and end leakage magnetic flux coefficient of the motor. Based on the proposed semi-analytical model,a 2-pole 6-slot motor was designed to verify the effectiveness of this method. The research results show that the time required for the semi-analytical calculation model is nearly 120 times less than that of the three-dimensional finite element simulation,with an error within 2%. Compared with the experimental results, the error is less than 5%, providing a reference for the design and optimization of hollow cup motor.

Key words: hollow cup motor, semi-analytical method, two-dimensional magnetic flux, winding factor, end leakage flux factor
