摘　　要：针对轴向磁化圆筒永磁直线同步电机,提出了一种基于圆柱坐标的洛仑磁力体积分解析计算电磁推力的方法,并利用该解析法对无槽和有槽电机的电磁推力进行了较详尽的分析计算,得出了解析计算结果。然后,利用有限元分析法,对该计算结果进行了验证。两种计算结果完全一致,证实了该解析计算方法的正确性,该方法计算结果不受积分路径选择的影响,计算精度较高。This paper presented an analytic electromagnetism force calculation method based on Lorenz force of tubular reference frame with bulk integral.The method is a new research way to work on the tubular permanent magnet linear synchronous motor.Due to this method,an elaborate academic analysis can be done to electromagnetism force of both slotted motor and non-slotted motor so as to obtain the calculation analytic results.The finite element method was used to testify the former calculation,and the result shows that there is little difference between the results of the two methods,which proved the correctness of proposed method.And the calculating result by the new method is not affected by the integral selective path and the calculation is highly accurate.
