The invention relates to the technical field of maglev trains, in particular to a coil type permanent magnet electric levitation driving device for a maglev train. The permanent magnet of the Halbacharray replaces an original superconducting magnet to serve as a vehicle-mounted magnet and interacts with the zero-flux coil to achieve suspension and guide integration. The center of the first Halbach array magnet deviates downwards from the center of the zero-flux coil, so that the upper magnetic flux and the lower magnetic flux are different, the upper portion of the coil is opposite to the vehicle-mounted magnetic pole, the lower portion of the coil is the same as the vehicle-mounted magnetic pole, and therefore an upward suspension force is generated. Permanent magnets of a second Halbacharray are arranged at the bottom of the vehicle body, a long stator synchronous linear motor is adopted on the ground for propulsion, and stable propulsion is achieved. The single side of the permanent magnet adopting the Halbach array can reach a relatively large magnetic field, and the permanent magnet adopting the Halbach array replaces an original superconducting magnet to serve as a vehicle-mounted magnet without cooling under the requirement of the required magnetic field intensity, so that a complex cooling system and an auxiliary system are omitted, the cost is greatly reduced, and the structure is simplified.
本发明涉及磁浮列车技术领域,具体而言,涉及一种用于磁浮列车的线圈式永磁电动悬浮驱动装置。本发明通过用Halbach阵列的永磁体代替原有超导磁体作为车载磁体,与零磁通线圈相互作用实现悬浮和导向一体。第一Halbach阵列磁体中心向下偏离零磁通线圈中心,使上下磁通量不一样,线圈上部与车载磁极相反,线圈下部与车载磁极相同,从而产生向上的悬浮力。在车体的底部布置第二Halbach阵列的永磁体,地面采用长定子同步直线电机推进,实现平稳推进。采用Halbach阵列的永磁体单边可以达到比较大的磁场,在所需磁场强度的要求下,Halbach阵列的永磁体代替原有的超导磁体作为车载磁体不需要冷却,省去了复杂的冷却系统和辅助系统,大大减少了成本,简化了结构。
