Abstract

In this paper, a permanent magnet synchronous machine (PMSM) with an auxiliary winding (AW) on the rotor is analyzed by two-dimensional approach. This PMSM with AW (AWPMSM) can be used in many applications such as propulsion system, aircraft and traction because it includes rotor flux control capability. First, the magnetic field in different parts of AWPMSM is calculated based on Maxwell equations. Then, as a consequence of the magnetic field, the torque components, including cogging, reluctance, electromagnetic and instantaneous torque are computed. Next, torque-speed characteristic has been investigated. This AWPMSM can be located in the flux weakening mode in two ways, first one is to attenuate the rotor field by changing the direction of the AW field and the other one is to adjust the armature current angle, both of them have been investigated. After that, the overload capability and temperature effects have been analyzed. Finally, using the meta-heuristic algorithms such as genetic algorithm, particle swarm optimization, differential evolution and teaching learn base optimization the dimensions of AWPMSM and the initial angle of the rotor are determined in such a way that the torque-to-volume ratio is maximized. The influences of the type of armature winding and the magnetization patterns have also been investigated. The results obtained by the two-dimensional method have been confirmed numerically.

摘要

本文采用二维方法对一种转子上带有辅助绕组（AW）的永磁同步电机（PMSM）进行了分析。这种带辅助绕组的永磁同步电机（AWPMSM）由于具备转子磁通控制能力，可应用于许多领域，如推进系统、飞机和牵引等。首先，基于麦克斯韦方程计算了AWPMSM不同部分的磁场。然后，根据磁场计算了包括齿槽转矩、磁阻转矩、电磁转矩和瞬时转矩在内的转矩分量。接下来，研究了转矩-速度特性。该AWPMSM可通过两种方式进入弱磁模式，第一种是通过改变辅助绕组磁场方向来减弱转子磁场，另一种是调整电枢电流角度，对这两种方式都进行了研究。之后，分析了过载能力和温度影响。最后，使用遗传算法、粒子群优化算法、差分进化算法和基于教学学习的优化算法等元启发式算法，以最大化转矩体积比的方式确定了AWPMSM的尺寸和转子初始角度。还研究了电枢绕组类型和磁化模式的影响。通过二维方法获得的结果已通过数值验证。
