摘要
目前,传统同步磁阻电机三层磁通屏障的转子设计性能较好、制造简易,得到行业的认可。讨论转子的不对称磁通屏障结构与磁通屏障结构变形对全面掌握同步磁阻电机的特性至关重要,因此该文研究了在不同功率等级下同步磁阻电机不对称设计规律以及基于序贯田口稳健优化方法的类凸极转子同步磁阻电机。首先对传统同步磁阻电机在一定功率等级下优化计算,得出抑制转矩脉动的不对称设计规律;然后根据开关磁阻电机凸极结构,设计类凸极转子同步磁阻电机,应用序贯田口稳健优化方法对采用分布式绕组的12槽8极电机优化得到最优功率等级,并应用至集中式绕组电机,应用磁路模型以及有限元仿真对采用不同绕组的电机作性能对比分析;最后提出一种结构更加简单、制造成本更低的同步磁阻电机。
At present,the design for rotor of the traditional synchronous reluctance machine(SynRM)with three-layer flux barrier has better performance and convenient manufacture,which has been recognized by the industry.Discussing the asymmetric magnetic flux barrier structure and the deformation of the magnetic flux barrier structure of the rotor is very important to fully grasp the characteristics of SynRM.Therefore,the asymmetrical design principle of SynRM under different power levels and the SynRM with quasi-salient pole rotor based on sequential Taguchi robust optimization method have been proposed.First of all,the asymmetrical design principle of restraining torque ripple is obtained by optimizing the traditional SynRM according to a certain power level.Then based on the salient rotor structure of switched reluctance machine(SRM),the SynRM with quasi-salient pole rotor is designed.The sequential Taguchi robust optimization method(STROM)has been used to get the optimal size of the 12-slot/8-pole machine with the distributed winding.The performance of the machine with different windings has been compared and analyzed by using the magnetic circuit model and finite element method.Finally,a SynRM with simpler structure and lower manufacturing cost is proposed.
