新能源汽车三相异步电机结构原理解析

Analysis of the Structural Principles of Three Phase Asynchronous Motors for New Energy Vehicles

本文介绍了异步电动机基本的原理,单相异步电动机和三相异步电动机的结构原理,并通过对比明确了不同的异步电机之间的区别与联系。新能源汽车用三相异步电机是三相异步电机在汽车领域的特殊应用,其结构原理与工业用电动机基本相同,但因为工况复杂,在工作模式、冷却方式等方面存在很大的不同。

This article introduces the basic principles of asynchronous motors,the structural principles of single-phase asynchronous motors and three-phase asynchronous motors,and clarifies the differences and connections between different asynchronous motors through comparison.The three-phase asynchronous motor used in new energy vehicles is a special application of three-phase asynchronous motors in the automotive field.Its structural principle is basically the same as industrial electric motors,but due to the complex working conditions,there are significant differences in working modes,cooling methods,and other aspects.
