【摘要】：同步磁阻电机具有价格低廉、加工简单、结构可靠以及转矩密度较高等优点,近年来在一些低成本交流调速领域得到了关注。然而,同步磁阻电机待优化参数众多,优化设计困难,且电机固有功率因数低、转矩脉动较大。研究同步磁阻电机的设计方法,以及结构参数对电机性能的影响,对于推广其在工业领域的应用,具有十分重要的意义。本文首先总结了同步磁阻电机的常规设计方法,指出每种设计方法的实现流程,分析其优缺点及适用条件。进而提出一种电机性能的快速预测方法,适合电机结构参数的前期初步设计。进而研究了电机结构参数对性能的影响,详细讨论了同步磁阻电机的极对数、裂比、绕组形式、定子铁芯以及转子铁芯的设计规律,为同步磁阻电机的优化设计提供了参考。最后将同步磁阻电机的定转子与开关磁阻电机的定转子分别组合,得到四种不同结构形式的电机,研究了四种电机的性能差异及各自优势。并对比了同步磁阻电机与永磁辅助同步磁阻电机,详细讨论了两种电机的工作特性。
[Abstract]:Synchronous reluctance motor has many advantages, such as low cost, simple processing, reliable structure and high torque density. In recent years, it has been paid attention to in some low-cost AC speed regulation fields. There are many parameters to be optimized for synchronous reluctance motor, so it is difficult to optimize design, and the inherent power factor is low and torque ripple is large. The design method of synchronous reluctance motor and the influence of structure parameters on the performance of synchronous reluctance motor are studied. This paper summarizes the conventional design methods of synchronous reluctance motor and points out the realization flow of each design method. The advantages and disadvantages and applicable conditions of the motor are analyzed. Then a fast prediction method of motor performance is proposed, which is suitable for the preliminary design of motor structural parameters, and the influence of motor structural parameters on performance is also studied. The pole logarithm, split ratio, winding form, stator core and rotor core of synchronous reluctance motor are discussed in detail. It provides a reference for the optimal design of synchronous reluctance motor. Finally, the stator and rotor of synchronous reluctance motor and the stator and rotor of switched reluctance motor are combined separately to obtain four kinds of motor with different structure. The performance differences of four kinds of motors and their respective advantages are studied. The synchronous reluctance motor and the permanent magnet auxiliary synchronous reluctance motor are compared, and the working characteristics of the two kinds of motors are discussed in detail.
