The invention discloses a magnetic levitation magnetic pole, an adjusting method and device for coil current of the magnetic levitation magnetic pole and a medium, and is applied to the technical field of magnetic levitation motors. The magnetic levitation magnetic pole in the scheme comprises a direct current magnet exciting coil, a current-adjustable alternating current magnet exciting coil and a controller. The controller is used for monitoring the state of the maglev train in the running process of the maglev train so as to obtain the suspension force change condition of the maglev train and adjusting the current of the alternating current magnet exciting coil according to the suspension force change condition of the maglev train. Therefore, the dynamic response capability of the excitation coil is only related to the electrical constant of the alternating current excitation coil, and the suspension force provided by the alternating current excitation coil is small, so that the number of turns and the current of the alternating current excitation coil are low, the electrical constant is smaller than that of a single coil in the original scheme, and the dynamic response capability is improved. In addition, after the current and the number of turns of the two coils are determined through calculation, magnetic pole power consumption near a magnetic levitation magnetic pole working point can be reduced, and therefore magnetic pole heating and temperature rise are reduced.

    本申请公开了一种磁浮磁极、磁浮磁极的线圈电流的调整方法、装置及介质,应用于磁浮电机技术领域。本方案中的磁浮磁极包括直流励磁线圈、电流可调的交流励磁线圈以及控制器。控制器用于在磁浮列车运行过程中,监控磁浮列车的状态以获取磁浮列车的悬浮力变化状况,并根据磁浮列车的悬浮力变化状况调整交流励磁线圈的电流。因此本方案励磁线圈的动态响应能力只与交流励磁线圈的电气常数有关,而交流励磁线圈需提供的悬浮力较小,因此交流励磁线圈的匝数、电流较低,电气常数相较于原方案的单个线圈更小,动态响应能力提高。此外,经过计算确定出两个线圈的电流和匝数之后,能够降低磁浮磁极工作点附近的磁极功耗,从而减小磁极发热与温升。
