ABSTRACT:
A wheel motor for a vehicle has an electric motor which is arranged in a central space defined in a wheel, to rotatively drive the wheel. A gear reducer is also arranged in the central space of the wheel. The electric motor includes a housing fixed to the vehicle body, a stator secured to the housing, a rotor rotatably fitted in a central space defined in the stator to generate the rotative driving force during rotation thereof, and an output shaft connected through the gear reducer to the rotor to be rotatively driven thereby, for transmitting the rotating output from the rotor through the gear reducer to the wheel. The output shaft extends through an axial through hole formed in the final stage gear of the gear reducer and an axial through hole formed in the rotor, and is rotatably supported by opposite end portions of the housing. An electric circuit for driving the electric motor is arranged in the central space of the wheel, together with the electric motor.
