The invention relates to a lightweight motor which comprises a hub cover, an end cover, a motor middle shaft, an end cover side motor shaft and a hub cover side motor shaft, wherein the end cover side motor shaft and the hub cover side motor shaft are located on the two sides of the motor middle shaft, the motor middle shaft, the end cover side motor shaft and the hub cover side motor shaft are coaxially arranged, a rotor is arranged on the outer side of the motor middle shaft in a surrounding mode, and a stator is arranged on the outer side of the rotor in a surrounding mode. The motor further comprises an input gear, a transmission gear set and an output gear, the transmission gear set comprises a gear shaft, a first gear and a second gear, the first gear is meshed with the input gear, and the second gear is meshed with the output gear. Compared with the prior art, the diameter of the middle shaft of the motor is small, the requirement of a small-size motor is met, the weight of the motor is further reduced, the diameter of the end cover side motor shaft and the diameter of the hub cover side motor shaft are large, supporting is more stable, the structure is simple, the number of gears is small, the weight is light, the size is small, the lightweight design requirement is met, the technological requirement is small, and the design difficulty is small.

    本发明涉及一种轻量化电机,包括轮毂盖、端盖、电机中轴、位于所述电机中轴两侧的端盖侧电机轴和毂盖侧电机轴,所述电机中轴、端盖侧电机轴以及毂盖侧电机轴同轴设置,所述电机中轴的外侧环绕设置有转子,所述转子的外侧环绕设置有定子,还包括输入齿轮、传动齿轮组和输出齿轮,所述传动齿轮组包括齿轮轴、第一齿轮和第二齿轮,所述第一齿轮与所述输入齿轮啮合,所述第二齿轮与所述输出齿轮啮合。与现有技术相比,本发明中电机中轴直径较小满足小尺寸电机的需求,进一步减轻电机重量,端盖侧电机轴和毂盖侧电机轴直径较大,支撑更加稳定,结构简单,齿轮数量少,重量轻,体积小,满足轻量化设计要求,工艺要求少,设计难度小。
