采用磁路分析方法对城市轨道交通用铁芯单极直线同步电动机进行了设计研究。采用合适的磁场或电流角，效率，功率因数和输出功率与总输入伏安的比值均优于85%。其他参数包括磁场或电枢电流、轨条尺寸、齿或槽长度、频率等，被检查并发现相对不敏感。控制选项进行检查和磁场削弱，磁场或电流角控制，或电枢电流控制都似乎是可行的替代方案。
Magnetic circuit analysis is used for a design study of an iron-cored homopolar linear synchronous motor (LSM) for urban transit application. Using a suitable field or current angle, efficiency, power factor, and ratio of output power to total voltamps input are all calculated to be better than 85 percent. Other parameters including field or armature current, rail bar size, tooth or slot length, frequency, etc., are examined and found to be relatively insensitive. Control options are examined and field weakening, field or current angle control, or armature current control all appear to be feasible alternatives.
