摘要
本文对交流电机定子圈式线圈的股线电流进行了实测,验证了空载时的股线环流,测定了环流中的谐波分量,并进行了定量分析,采用了新的联接方法,大幅度降低了基波和谐波环流,股线电流分布不均衡系数从1.57降低到1.07。
Measurements of the strand current in the stator barrel type coil of AC mach- ines have been successfully made.The strand circulating current at no load has been verified.The measurements and quantitative analysis of the harmonic components of circulating current have been made. A new connecting way has been used and circulating current losses have been greatly reduced.The nonuniform strand current distribution factor has been reduced from 1.57 to 1.07.
