1. A direct drive traction vehicle motor system for a wheeled vehicle including a vehicle wheel removably attachable to a vehicle axle hub by a wheel mounting structure, the motor system comprising:

  • a passive electric motor rotor for mechanical attachment to the wheel mounting structure for rotational movement with the vehicle wheel;

    an attachment structure for concentrically mounting the rotor in a fixed relation to the vehicle wheel, the attachment structure including the wheel mounting structure;

    an active electric motor stator mounted in a concentric relationship with the rotor;

    a mechanical structure coupled between the vehicle and the stator for inhibiting rotation of the stator;

    an electric drive circuit electrically coupled to the motor stator for exciting the motor stator to impart a rotational force on the vehicle wheel through the rotor; and

    wherein an electromotive force is applied to the wheel by the rotor without any use of reduction gearing.
