A wheel arrangement 10 comprises a hub indicated generally at 12 and a wheel indicated generally at 14 and rotatable around the hub 12. The hub 12 and wheel 14 are arranged to cooperate to form an electromagnetic motor by which the wheel 14 may be driven relative to the hub 12. This motor includes a flux path which is provided, at least in part, through components of the wheel 14, in particular the circumferential wall portion 14B which serves to connect together the two disc-like members 14A in order to clamp a tyre 26 therebetween. This allows the synchronous motor to be built at a large radius from the axle 18, thereby optimising the torque which the motor can provide. <IMAGE> |
