【摘要】 大气隙直线感应电机(气隙长度大于10mm)目前已经在地铁、轻轨中得到了很好的应用,其在低速磁浮领域也将会有很好的应用前景.它与小气隙直线感应电机有很大不同,因此需要对该类型电机的特性以及驱动有较深入的研究.本文在直线感应电机DUNCUN等效电路的基础上,借助有限元分析,获得等效电路参数,进而建立了大气隙直线感应电机的等效电路模型.在此基础上建立了大气隙LIM考虑动态纵向边端效应的矢量控制系统仿真模型,通过仿真分析,对矢量控制系统中比较关键的问题进行了探讨。结论将为此类型电机控制系统设计提供参考。更多还原

【Abstract】 The large air gap linear induction motor(air gap length is greater than 10mm)is well used in metro,light rail now,and also will have a nice future in Low-speed Maglev Vehicle.There are many differences between large air-gap linear induc-tion motor and the small air-gap ones.It is necessary to do some research for the characteristics and driven technique of large air-gap linear induction motor.The paper introduced the DUNCUN equivalent circuit model for linear induction motor.By implementing FEM analysis of one large air-gap linear induction motor,the parameters for the DUNCUN equivalent circuit model were extracted.Then taking dynamic longitudinal end effect of this LIM into consideration,the secondary flux oriented control simulation model of this LIM is developed.Via simulation analysis,some of the key points about field oriented con-trol was discussed.As a result,they can supply some good tips to driven system design of this kind of motor.更多还原
