<p>The apparatus has hub casing having two hub casing sides (1,2) which are rotatably mounted on the axle (5). A stator (9) of the electric motor, is rotationally connected to the axle. A hub arranged in hub casing is connected to the rotor (6b) of the electric motor. The air guide units are arranged in the inner sides (1a,2a) of the hub casing sides. The air in the inner sides of the hub casing sides is radially moved in opposing directions, by the rotation of the hub casing, so that targeted circulation of air in the hub casing is achieved.</p> |
