The Design and Experiments of the Permanent and Current-excitation Alternative Hybrid Linear Synchronous Motor

介绍了一种新型结构的永磁电励交替混合式直线同步电动机,建立了磁路模型和数学模型。并对样机进行了各种特性试验,对其中典型的推力-电流关系作了具体介绍,给出了不同频率下推力-电流的变化曲线。试验结果验证了所建电机模型的正确性。

A novel hybrid permanent linear synchronous motor, which adopts permanent poles and current-excitation poles alternative distribution structure,is introduced in this paper.The magnetic circuit model and mathematical model are established.On the basis of the analysis, an example motor is designed and many character experiments are developed. Some typical results about thrust-current are concluded and the changing curves of thrust-current are given. The correctness of the motor model is verified by experimental results.
