Cylindrical linear synchronous motors with permanent magnets have merits of compactness, high efficiency and easy to support because of no end-windings and negligible radial force. A propulsive force simulation method of the cylindrical linear synchronous motors was developed using FEM analysis code ANSYS, and the simulation results were well agreed with the test results of an experimental machine, which shows the effectiveness of the simulation method. Two kinds of countermeasures for decreasing propulsive force fluctuations were proposed and the effects of their countermeasures were cleared using the simulation method. One of them are the novel countermeasure, in which the separated two armatures are used and excited from phase shifted currents by the electrical phase angle difference corresponding to the separated position, and it is found that the novel countermeasure was very useful.
