A wheel hub electric motor assembly 10 for a wheeled vehicle. The wheel hub electric motor assembly 10 comprises an electric motor 18 having a rotor 36, a stator 34 and a hub assembly (21, Figure 5) having formations which enable a vehicle wheel to be connected thereto. The hub assembly (21) has a base member 76, a rotor member 78 and bearing 80 disposed therebetween. The base member 76 of the hub assembly (21) is releasably connected to the stator 34. The rotor member 78 of the hub assembly (21) is coupled for rotation with the rotor 36 of the electric motor 18. The wheel hub electric motor assembly 10 further includes a bearing arrangement 64 provided between the rotor 36 and the stator 34 of the electric motor 18. Preferably the hub assembly (21) can be removed from a wheel hub electric motor assembly 10 without affecting the alignment if the rotor 36 and stator 34, the alignment of the rotor 36 and stator 34 being maintained by the bearing arrangement 64. |
