The invention provide a hub motor, which includes: a motor shaft (1), which is fixed and non-rotational, a hub housing (11), which is connected to the motor shaft (1) via bearings, a stator (2) of the motor with winding, which is fixedly connected to the motor shaft (1), wherein, the hub motor further includes an outer rotor (3) of the motor and a quasi-planet reduction gear drive mechanism, which includes a sun gear (5), several planet gears (6), a ring gear (9) and a planet carrier (8), wherein the sun gear (5) is fixedly connected to the outer rotor (3) of motor, and the planet gears (6) drive the hub housing (11) to rotate. The hub motor of this invention adopts outer-rotor motor, in which the outer rotor (3) 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, thus it has very high use value.
