Tradition of responding the electric motor and exists in the special situation in siding a lot of and obvious lack. Such as: Start to turn the small length of the turning, start the small etc. of electric current. Three waves start to namely attain high start to turn the length of the turning, and again make start as soon as, always accelerate but attain the sum to settle to harmonic to increase a more perfect situation, for the social large quantity of its direction expansion, the application creates relates really fine term. Proposed is a rotor winding for induction motor harmonic starter. The winding is composed of a cage winding mainly for starting and a winding operation. Without using brushes and collector rings,rotor winding is simplified. Operation reliability, maintenance and starting performance are enhanced.Keywords: rotor winding;harmonic staring; induction motor 第1章 绪 论 1.1传统感应电动机的特点和存在的问题 1.1.1 传统感应电动机的特点 感应电动机是基于气隙旋转磁场与转子绕组中感应电流相互作用产生电磁转矩,从而实现能量转换的一种交流电动机。其转速和同步转速之间存在一定的差异(即所谓的异步),这是它产生转矩的必要条件。由于转子绕组电流是感应产生的,因此称为感应电动机。
