1、中文摘要摘要随着电机技术的发展，变频异步电机越来越广泛地应用在各种工业领域。而变频系统的使用也给电力电子与电气传动学科带来了新的研究课题，即在变频器供电下异步电机的设计与分析。本文从变频异步电机的电磁设计出发，首先将传统异步电机的设计方法与变频调速异步电机的设计方法进行了比较。指出了传统异步电机设计方法在变频调速异步电机设计中存在的局限性。而在变频调速异步电机设计中，电机的转子槽数、槽形和绝缘设计都与传统异步电机的设计有所区别，并具有其优越性。本文详细而系统地分析了变频调速异步电机中电磁的产生机理，论述了磁场对异步电机运行性能的影响。根据磁场的特点，从电磁设计方面提出了变频异

2、步电机中设计的方案。本文在变频调速异步电机电磁设计的基础上，设计了一台220V500W适用于变频器供电的异步电机。关键词：变频器，异步电机，电磁设计-I-AbstractAbstractFollowingwiththedevelopmentofpowerelectronicstechnology,theinverter-driveninductionmotoriswidelyusedinallkindsofindustryfield.Theutilityofvariablefrequencyandadjustablespeedsystemsbringsanewresearch
