摘　　要：本文采用圆柱坐标系进行了实芯转子异步电机二维非线性磁场分析和参数计算,确立了转子波阻抗Z_r与转子阻抗Z′_2之间的关系,引入系数K_A.同时,将圆柱坐标系与直角坐标系二维线性分析进行了比较,引入了两种坐标系之间转子波阻抗折合系数K_r及磁场特征根之间的关系式.对于工程设计中广泛采用的直角坐标系分析,本文考虑了转子曲率、电机极数及非线性磁场等因素的影响,使转子参数计算趋于完善和准确.计算表明,将圆柱坐标系的转子参数进行转换,对于小转差运行时,实芯转子异步电机及异步运行状态下的汽轮发电机参数计算结果更符合实测数据,This paper presents the field analysis and parameter calculation of a solid rotor induction motor operating at small slip. The analysis is based on the cylindrical coordinates in order to take into account the curvature effect of the rotor. The solution of Maxwell's equation for a solid rotor induction motor has been obtained using magnetic vector potential A. A cylindrical model and a rectangular one are dealt with. The calculated results are compared. The relationship between the rotor parameters of the two models is discussed and the curvature coefficient K is given.
