【摘要】 本文从麦克斯韦方程出发，在圆柱坐标系下建立了圆筒型直线电机的多层理论分析模型，用该模型对一台样机进行实例计算，并与磁阻抗法和实验值进行了比较，计算结果表明该方法的正确性和有效性更多还原

【Abstract】 Based on Maxwell’s equation, the paper develops a multi layer theory under 2 dimensional cylindrical coordinates and applies it to the analysis of a cylindrical linear induction morot. The calculations are compared with test and those obtained from using the method of magnetic impedance. The results show that the approach is correct and effective.更多还原
