A high-torque motor device, comprising: a shaft, an electromagnetic unit with a stator and a rotor, and a single-stage planetary gear unit set onto the rotor. The single-stage planetary gear unit is provided with a planetary gear disk firmly sleeved onto the shaft, a plurality of planetary gears pivoted onto the planetary gear disk, an internal ring gear meshed with the planetary gear, and a sun gear fixed onto the rotor and meshed with the planetary gear. The present invention allows a single shaft between the motor and planetary gear unit, thus shortening the axial length of entire device and further guaranteeing the assembly precision of parts. This structure can be applied to motor and generator.
