摘　　要：本文针对轴向磁化圆筒永磁直线同步电机,介绍了一种基于圆柱坐标的标量磁位许-克变换的磁场解析计算方法,并利用该解析法对无槽电机的气隙磁场分布进行了较详尽的理论分析,还得出了计算解析结果。然后利用有限元分析法,对该计算结果进行了验证。结果显示,对于大气隙解析计算结果比较接近磁场的平均值,而小气隙电机两种计算方法的结果误差很小,从而验证了许-克变换法的正确性和实用价值。In this paper,an analytic magnetic field calculation method based on scalar quantity magnet of tubular reference frame with Schwartz-Christopher Transform is introduced,which is a new research way to work on the tubular permanent magnet linear synchronous motor.Thanks to this method,an elaborate academic analysis to magnetic field distribution of non-slotted motor is conducted,as well as the calculation analytic results.Meanwhile,Finite element analytic method is used to testify the former one.The verification shows that there is almost no difference in both of the error results in narrow slot,while in wider slot,the analytic calculation value nearly equals to the mean value of the motor magnetic field.
