The invention provides a hub motor assembly and a gardening tool, and particularly relates to the field of gardening tools. The hub motor assembly comprises a walking wheel, an outer rotor motor and a speed reducing mechanism, an inner gear ring is arranged in the walking wheel, the outer rotor motor is arranged in the walking wheel, an outer gear ring is arranged on the outer side of the outer rotor motor, the speed reducing mechanism comprises a planet carrier and at least one planet gear, and the planet carrier is arranged between the walking wheel and the outer rotor motor. The planetary gear is rotationally installed on the planetary carrier, internally meshed with the outer gear ring and externally meshed with the inner gear ring. The outer rotor motor drives the planetary gear to rotate through the outer gear ring, and the planetary gear drives the inner gear ring to rotate so as to drive the walking wheels to rotate. The hub motor assembly provided by the invention has the characteristic of high torque output, and can output high torque while realizing low rotating speed of the motor; meanwhile, the overall structure is small in size and small in occupied space.

    本发明提供一种轮毂电机总成和园林工具,具体涉及园林工具领域。该轮毂电机总成包括行走轮、外转子电机和减速机构,行走轮的内部设有内齿圈,外转子电机设置在行走轮的内部,外转子电机的外侧设有外齿圈,减速机构包括行星架和至少一个行星齿轮,行星架设置于行走轮与外转子电机之间,行星齿轮转动安装在行星架上,且行星齿轮与外齿圈内啮合,与内齿圈外啮合。外转子电机通过外齿圈驱动行星齿轮转动,行星齿轮驱动内齿圈转动进而驱动行走轮转动。本发明的轮毂电机总成具备高扭矩输出的特点,可以实现电机低转速的同时输出高扭矩;同时,整体结构体积小,占用空间小。
