The invention relates to the field of motors, in particular to an axial magnetic flux motor suitable for an electric shared bicycle, which comprises an axial magnetic flux motor body, the recovery braking system can convert kinetic energy generated when the axial flux motor body brakes into electric energy; when the controller system detects that the current of the axial magnetic flux motor body is cut off, the controller system adjusts the state of the axial magnetic flux motor body into a power generation state and switches the recovery braking system into a working state; the energy storage device comprises a storage battery and a super capacitor, in the initial stage of braking, the axial flux motor body has large kinetic energy, and most of the energy is stored in the storage battery in a reverse charging mode through the controller system; along with braking, the rotating speed of the axial magnetic flux motor body is continuously reduced, after the rotating speed of the axial magnetic flux motor body is reduced to a threshold value, braking enters a later stage, and a small part of energy converted from kinetic energy charges the super capacitor. The braking kinetic energy can be efficiently recycled.

    本发明涉及电机领域,特别是一种适用于电动共享单车的轴向磁通电机,包括轴向磁通电机本体;回收制动系统:能够将回收轴向磁通电机本体制动时的动能转换为电能;控制器系统:控制器系统在检测到轴向磁通电机本体的电流被切断,控制器系统将轴向磁通电机本体的状态调整为发电状态,并将回收制动系统切换至工作状态;储能装置包括蓄电池和超级电容,制动的初始阶段,轴向磁通电机本体具有较大的动能,通过控制器系统将大部分能量以反向充电的方式存储在蓄电池中;随着制动的进行,轴向磁通电机本体的转速持续下降,等到轴向磁通电机本体转速下降到阈值后,制动进入后期阶段,动能转换的小部分能量对超级电容充电。本发明能够高效回收制动动能。
