  • Patent number: 7357743
    Abstract: Provided herein is a hub motor, which includes: a motor shaft, which is non-rotational (e.g., fixed), a hub housing, which is connected to the motor shaft via bearings, a stator of the motor with winding, which is fixedly connected to the motor shaft, wherein, the hub motor further includes an outer rotor of the motor and a quasi-planet reduction gear drive mechanism, which includes a sun gear, a plurality of planet gears, a ring gear and a planet carrier, wherein the sun gear is fixedly connected to the outer rotor of motor, and the planet gears drive the hub housing to rotate. The hub motor of this invention adopts outer-rotor motor, in which the outer rotor rotates and is directly connected to the reducer mechanism.

    Abstract: The invention provide a hub motor, which includes: a motor shaft, which is non-rotational (e.g., fixed), a hub housing, which is connected to the motor shaft via bearings, a stator of the motor with winding, which is fixedly connected to the motor shaft, wherein, the hub motor further includes an outer rotor of the motor and a quasi-planet reduction gear drive mechanism, which includes a sun gear, a plurality of planet gears, a ring gear and a planet carrier, wherein the sun gear is fixedly connected to the outer rotor of motor, and the planet gears drive the hub housing to rotate. The hub motor of this invention adopts outer-rotor motor, in which the outer rotor rotates and is directly connected to the reducer mechanism. Therefore, the output power per unit weight (volume) is greater, as compared with other electric hubs of the same power, the bulk of the hub motor of this invention is relatively smaller, and thus it has very high use value.
