摘　　要：随着国内越来越多大容量变频调速同步电动机采用LCI变频装置,对采用LCI变频同步电动机的认识逐渐深入,本文介绍了基于LCI变频调速轧钢用三相同步电动机设计的特点,重点介绍了湘潭电机生产的TBPKS900-6 4000kW 482/1500r/min 3150V三相同步电动机的设计原则,对该型电动机的绝缘结构、防轴电流措施、阻尼绕组设计进行了说明,通过对同步电动机进行Ansoft有限元分析,判定采用类比设计方法能够满足要求。With LCI convertor is popular scheme for high-power capacity variable frequency adjustable speed synchronous machine, study on LCI synchronous motor is developed. This paper presents the design principles of LCI variable frequency adjustable speed synchronous motor, and introduces XEMC new type variable frequency adjustable speed synchronous motor TBPKS900-6 4000kW 482/1500r/min 3150V, and explains the synchronous machine design principles including insulation configuration, preventing shaft current measure and full-damper winding. Through finite element analyzing the electromagnetic field making sure the performance of the synchronous machine can meet the client request.
