摘　　要：将传统无刷双馈电机的原理应用于直线电机,提出一种新型电机即直线无刷双馈电机。阐述了该电机的工作原理,利用有限元仿真软件对一台采用特殊笼型动子的直线无刷双馈电机进行建模仿真,得出仿真结果(包括电机的磁力线分布、电机动子移动速度与动子和定子绕组频率之间的对应关系、电机的气隙磁密谐波分析以及电机的的功率与效率分析)与理论分析相一致,从而证明了直线无刷双馈电机的合理性及可行性,为无刷双馈原理在直线电机中的应用提供理论指导。The theory of traditional brushless double fed machine （BDFM） was introduced to linear motor （LM）, thus a new type of LM was proposed, which was named as linear brushless double fed machine （LBDFM）. The work principle of LBDFM was introduce, then the LBDFM which used special cage mover was modeled and simulated by the finite element software. According to the simulation results which included the distribution of magnetic line, the corresponding relation between speed and frequency of the LBDFM, air gap magnetic flux density analysis of the LBDFM , the power and efficiency analysis, the feasibility and rationality of this new machine were verified, which could provide theoretical guidance for further research about LBDFM.
