摘    要:针对EMS磁悬浮列车的零电流型永磁电磁混合磁铁,研究其永磁体和电磁线圈结构参数的设计方法.永磁体安装在磁轭部位,其截面积不受磁极面积的限制,研究得出永磁体的厚度与其截面积的约束关系,并给出永磁重量最小化的设计方法.根据最大平衡安匝数要求,研究得出相对于纯电磁铁,混合磁铁的电磁线圈匝数可减半.由于混合磁铁的可控性能低于纯...

关 键 词:磁悬浮  永磁体  永磁电磁混合磁铁  可控性

Abstract:To design the zero-power hybrid magnet with permanent magnets and electromagnets for EMS maglev vehicles,the structural parameters of its permanent magnets and electromagnets were researched on.The permanent magnet was located at the middle of the yoke,which made its sectional area independent from the area of the pole.The restriction between the thickness and the area of the permanent magnet was presented,and the method of designing the permanent magnet with minimum mass was given.According to the requirem...
Keywords:maglev  permanent magnet  hybrid magnet with permanent magnet and electromagnet  controllability
