摘　　要：分析了屏蔽电机磁场的特点，建立了似稳场的数学模型，用解析法求出了屏蔽电机的磁场分布，进而计算出屏蔽层的涡流损耗，并通过实验验证了解析方法的可行性．The calculation of shield layer for eddy current loss is an important problem for design of shielded motor.We analyze the characteristic of the magnetic field for this kind of motor and give a model of time variant electromagnetic field. The distribution of magnetic field is obtained by using the analysis methods, from which the eddy current loss is calculated out. The validity of this method has been proved by the measurements of the real motors.
