A modular, self-driven vehicle wheel assembly including a drive motor carried by the wheel assembly. The assembly includes a hub, a wheel rotatably mounted on the hub, and a planetary speed-reducing unit mounted on the hub and drivingly connected with the wheel. The drive motor is a shunt wound DC motor that is coaxially mounted adjacent to the wheel and within a chamber formed in the hub. The motor is drivingly connected with the planetary speed-reducing unit to transmit motor torque to rotate the wheel in either a forward direction or a reverse direction. A brake assembly is carried adjacent to the motor for selectively applying a braking force to brake the motor armature when the wheel is to remain in a stationary condition.
