交流牵引电机槽口冲片凸出的解决方法

Way to Solve Sheet-convex Problem on the Slot Opening of AC Traction Motors

针对采用焊接式机座的交流牵引电机,其定子铁心在叠片焊接后铁心两端紧邻端板的第一片冲片存在不同程度的凸出问题,进行了原因分析,并提出了解决措施。

Against the problem that the sheet-convex on the first plate of stator core sheets next to each end-plate appeared with various degree at the slot opening of AC trac- tion motors with welding-type frame after being laminated and welded, the cause was analyzed and method of solution was presented either.
