摘　　要：一些新型电机转子阻尼绕组的端部采用与转子冲片形状相同的阻尼铜片结构,本文将该阻尼端部铜片等效为多个导线,根据任意两长直导线之间电感的基本计算公式,由等效前后电感储能不变的原则,得出了电机端部阻尼铜片漏电感的计算公式。实际计算了某隐极电机的阻尼端部漏感,利用计算结果,仿真分析了电机定子三相突然短路时的电流波形。仿真结果与试验结果相吻合,验证了所提方法的有效性。The calculation of leakage inductance of the new type end copperplate of a round rotor machine is analyzed in this paper. Based on the basic inductance calculation formulas between two long direct wires, the leakage inductance of end copperplate is obtained by taking the end copperplate as a group of long direct wire. Using the parameter calculated, the simulation of a sudden short-circuit test of the machine was carried out. The simulation and test results prove that the formulas presented are correct.
