摘　　要：介绍了电控无级自动变速器ECVT的技术特点;同时强调了在电控无级自动变速器系统中,调节电动机是变速器实现其功能的关键零部件之一。由于调节电动机频繁启动,频繁换向,连续运转,且输出转矩变化范围大,工作电流大,同时工作环境温度也较高,这就要求该电动机可靠性好,工作寿命长。目前电控无级自动变速器调节电动机多采用永磁直流电动机。通过对某车型ECVT调节电动机结构的分析,初步探讨了ECVT调节电动机的工作特点和技术条件。The article simply introduces the technical feature of Electronic Continuously Variable Transmission. The article also emphasizes that regulative electric motor is one of key components in ECVT. Because of frequently starting, Frequently changing directions, Continuously running, And that the output torque changing greater, The current being greater, The environment temperature being higher, All these will be requested that regulative electric motor has good reliability and long life. Now regulative electric motor in ECVT are mostly adopted permanent magnetism DC Motor. Finally the article initially analyzes the work feature and technical specifications of regulative electric motor by means of analyzing regulative electric motor＇s composition in one vehicle.
