| 摘 要： | 本文先用有限差分法计算了额定负载时凸极同步发电机内的二维磁场分布,在此基础上,用麦克斯韦应力和安培力算出了电枢齿壁、电枢铁芯、主极表面和两侧、主极铁芯和载流导体上的切向磁场力以及相应的电磁转矩,画出了电机内切向磁场力的分布,并把算得的结果与传统法进行了比较.

| Abstract: | In this paper, using FD method, the 2D non-linear magnetic field in a 170MW salient pole synchronous generator at rated load is calculated at first, then the tangential forces and electromagnetic torques acting on the surfaces of stator teeth, body of teeth and yoke, surfaces and sides of main pole and stator, rotor winding are calculated by Maxwell stress method.The distribution of tangential forces is plotted and analysed. The results are compared with values of conventional method and the cause of error is discussed. |
