摘　　要：通过建立带阻尼绕组的大功率交－交变频凸极同步电动机的多回路数学模型，研究了在负载突然变化，不同阻尼绕组结构、导条根数、阻尼节距时，电动机的功角振荡、阻尼绕组瞬态电流、损耗等情况。结果表明；大功率交－交变频凸极同步电动机应设置成全阻尼绕组，且在极面上阻尼条靠近ｄ轴布置比阻尼条均匀布置要好。电机实际运行情况验证了结论的正确性。Oscillation of power angle, transient current along damper winding,loss etc. under sudden changed load as well as different damper winding construction, number of damper bars and their pitch are investigated by establishing of multi-circuit mathematical model for cycloconverter-fed Jarge power salientpole synchronous motor with damper winding.Result shows that the motor should be equiped with full damper winding, and its bars arragement near axis d on pole face is better than their uniform distribution.Practical operation of the motor confirms correctness of above-mentioned conclusion.
