摘要 介绍了笼型感应电机的发展历史,结合现有研究成果,就单斜槽和双斜槽两种基本转子结构,主要介绍了这两种斜槽各自的结构特点,简要阐述了其对气隙磁场基波和谐波分布的重要影响。系统性地回顾了科研人员在分析斜槽电机时所采用的二维有限元法、三维有限元法以及多层分段二维有限元法等分析方法以及取得的相应研究成果,并对比了各种方法的优缺点。针对这两种斜槽结构,进一步简要梳理了其对电磁噪声、附加损耗和起动转矩等电机性能的影响。并探索性地提出基于双斜槽转子等槽或者近等槽配合下有望实现高效低噪声感应电机的设计思路,为进一步探索提供参考。

Abstract:This paper reviews the development history of the squirrel cage induction machines. According to the current scientific achievements, the structures of the traditional skewed slot and double skewed slot are introduced. Their effects on the fundamental component and harmonics of the air-gap flux density are discussed respectively. The finite element methods, including 2D finite element method, 3D finite element method and multi-slice method, are compared. In addition, the effects of these two slots on the motor performance are clarified, such as electromagnetic noise, stray loss and starting torque. An design idea of ultra-silence efficient motor is proposed, based on double skew slot with equal slot combination.
Key wordsSkewed slot rotor    finite element method    electromagnetic noise    electromagnetic performance    starting torque
