摘　　要：针对双屏蔽电机端部结构件复杂,端部漏抗难以计算的问题。采用三维有限元数值解法对双屏蔽电机端部漏抗进行计算,利用端部漏抗计算结果采用二维场路耦合有限元法对双屏蔽电机性能进行计算,并将计算结果与实测值进行对比。在此基础上,分析了解析法在计算端部漏抗时产生误差的原因以及解析法的计算误差对电机性能计算的影响。计算结果表明:利用数值法计算端部漏抗得到的电机性能与实测值更接近,与数值法相比,由解析法计算误差引起的起动电流倍数和起动转矩倍数相对误差可分别达到11.75%和20.48%。计算结果为双屏蔽电机设计及计算提供了更准确的参考依据。For the complex end structure of double canned motor, it is difficult to calculate the end leak-age reactance. Numerical method based on three-dimensional finite element method was adopted to cal-culate the stator end leakage reactance of double canned motor. Then two -dimensional field -circuit coupling finite element method was utilized to calculate the performance of a double canned motor with the end leakage reactance calculation results. The performance calculation value was compared with the test value. Furthermore, the reasons of analysis method errors and the impacts of analysis method calcula-tion error on the motor performance were studied. The calculation results indicate that the motor perform-ances obtained by numerical method for end leakage reactance calculation is close to the measured val-ues. Compared with numerical method, the starting current ratio and starting torque ratio relative error calculated by analysis method are 11. 75% and 20. 48%, respectively. Calculation results provide more accurate references for the design and analysis of double canned motor.
