摘　　要：双速电机是传统多速电机变极对数有级调速形式之一,在我国广大工矿企业的调速传动应用中占有一定的比重。本文立足于双速电机的变频改造,在保证最小改造投入,提升工艺调速性能的基础上,完成了从有级调速向无级调速的平稳过度。Two-speed motors are traditional pole-changing multi-speed motor one step regulation logarithmic form, occupy a certain proportion in China＇s vast mining industry of speed drive applications. Based on the two-speed motor frequency transformation, the transformation of the guaranteed minimum investment, improve process speed performance, based on the completion of a smooth transition from level speed to variable speed.

关 键 词：三相异步双速绕线式电机 变频器调速 矢量控制 工艺调速
