A wheel assembly comprising a stator and a rotor housing the stator for relative rotation around the stator. The rotor has magnets for interacting with electrical winding of the stator to provide the relative rotation about a central longitudinal axis. The stator has openings extending from a stator proximal side to a stator distal side, and rotation of the rotor around the stator causes an air flow through the openings for heat dissipation. In normal operation of the wheel assembly, the air flows from the wheel assembly proximal side towards the wheel assembly distal side through the openings due to a centrifugal force created during rotation of the rotor around the stator. In an embodiment, an arm used to connect the stator to the chassis of the vehicle comprises through-openings along a longitudinal axis which is parallel to a movement direction of the vehicle to force air through the through-openings for additional heat dissipation from the stator.
