The invention discloses a high-power high-speed electric motorcycle hub motor which comprises a main shaft, a hub, a left end cover, a right end cover, a stator core and a stator support and further comprises fan blades on the left/right end cover and a wind tunnel on the stator core, the fan blades generate circulating air flow in the motor along with rotation of the motor, and the wind tunnel is a channel of the circulating air flow. The motor further comprises cooling fins which are arranged on the outer side faces of the left end cover and the right end cover, and further comprises heat absorption pieces which increase the internal surface area of the motor shell, and the heat absorption pieces are arranged on the inner side faces of the left end cover and/or the right end cover. According to the invention, axial strong air flow can be generated in the motor, heat can be quickly led out from the stator component, heat in air in the motor can be quickly absorbed to the motor shell, and then heat is quickly dissipated through the heat dissipation device outside the motor.
本发明公开一种大功率高速电动摩托车轮毂电机,包括主轴、轮毂、左端盖、右端盖、定子铁芯和定子支架,还包括左/右端盖上的风叶、定子铁芯上的风洞,风叶随电机的转动在电机内部产生循环空气流,风洞为循环空气流的通道,将定子铁芯内的热量排出,还包括散热片,散热片布置在左端盖和右端盖的外侧面,还包括增加电机壳体内部表面积的吸热片,吸热片设置在左端盖和/或所述右端盖的内侧面。本发明的电机内部能产生轴向的空气强流,将热量快速从定子部件中导出,还可以快速吸收电机内部空气中的热量至电机外壳,再通过电机外部的散热装置快速散热。
