Abstract
A vehicle having an electrical drive wheel hub system (30) and the hub system incorporated in the vehicle has a wheel hub (18) driven by an electric motor (31) formed by a brushless DC motor having stators (40) and rotors (42). The electric motor is arranged to drive an epicyclic gear system (32) which provides a reduction gear arrangement to drive the hub (18). Located entirely within the periphery of the stator is power circuitry and control circuitry for the electric motor, the circuitry being provided on toroidal printed circuit boards (70, 71).
