摘要
该文综述了直线电机在城市轨道交通和干线轨道交通的研究和应用现状。从直线电机的类型、拓扑结构、供电方式以及应用车辆的特征等方面,详细论述直线感应电机、常导直线同步电机、无铁心超导直线同步电机、永磁直线同步电机在轮轨车辆、中低速磁悬浮列车、单轨列车、高速磁悬浮列车等载运工具中的应用。详实阐述了在不同速度等级、车体支撑方式等轨道交通运输条件下,直线电机初/次级沿线路的铺设方式、法向力对悬浮或轮轨关系的影响,直线电机的冷却方式以及采用的不同控制策略等关键问题和技术。
Review of the application and progress in the linear motor for the urban rail and trunk-rail was presented.According to the motor type,topology,power supply and vehicle characteristics,the linear induction motor,conductive linear synchronous motor,superconductivity linear synchronous motor and permanent magnet linear synchronous motor,which are applied in the wheel-rail vehicle,medium and low speed maglev,monorail,and high-speed maglev,were discussed in detail.Under the rail transport conditions of different speed degree and support mode of car body,the key technology such as the laying way of the primary and secondary along the rail,the influence of the normal force on the suspension or wheel-rail relationship,cooling type and control strategy of the linear motor were presented.
