摘　　要：提出了一种应用于电磁发射场合的新型无槽双边长定子直线感应电机,该电机取消了传统电机的齿槽结构,增大了电机定子绕组的导电面积,降低了电机损耗和温升。基于电磁场有限元仿真计算得到了电机定子漏感和励磁电感的饱和特性,给出了电机非线性工况的计算方法。实验结果和计算结果的比较验证了计算方法的正确性。A novel slot-less double-sided long-stator linear induction motor is proposed for the application of Electromagnetic Launch. In this motor, the conventional gullet structure is cancelled, and conductive area of the motor stator windings is enlarged, and then the loss and temperature rise is decreased. Based on the finite element simulation and calculation of electromagnetic field, the saturation characteristics of stator leakage inductance and excitation inductance are obtained, and the calculation methods in nonlinear conditions of the motor are displayed. The comparison of experimental and calculation results verifies the validity and superiority of the proposed calculation methods.
