摘　　要：介绍了成都南车电机有限公司生产的3 300kW机车配套无刷励磁同步发电机引线端固定的改进方法。过去大部分的机车配套发电机引线端固定方法都是通过在定子铁芯轴向固定一定数量的支承螺杆来固定整个引线端系统,然而由于发电机径向的电磁振动,使该支承螺杆发生了不同程度的断裂。对该发电机的电磁振动进行了详细的分析,并提出了一种新的固定工艺方法,有效地解决了支承螺杆断裂、断裂后无法取出以及更换困难的缺点。The paper described a improving method of terminals fastening for a 3 300 kW brushless synchronous genera- tor made in my company. In the past, most terminals fastening for the locomotive alternator is to fix some support rods in the axial to fasten the fixed system in the stator. Because of the radial electromagnetic vibration, the support rods always break in different degrees. The paper focused on analyzing the electromagnetic vibration in detail and come up with a new project. It can solve the problems effectively which the support rods often break but can not be taken out.
