摘　　要：依据电磁场基本方程,推得汽轮发电机定子端部绕组区域磁场分布的统一表达式,以及各段绕组所受电磁力的计算式。通过计算,得到端部绕组区域磁感应强度和绕组所受电磁力的分布图,并对结果进行详细分析,指出不同区域电磁力最大值所在的位置及相应的数值。所得结论具有一定实际指导价值。Based on fundamental equations of electromagnetic field, the magnetic field distribution in the region of stator end windings of turbo-generator and electromaguetic forces acted on each segment of winding are formulated. By numerical method, the distn＇butions of magnetic induction intensity in the region of stator end windings and electromagnetic forces acted on winding are shown in manner of graphics. The results are discussed in details, the maximum electromaguetic forces and its locations are given. The conclusions have much practical value.
