Abstract: front page image
(EN)An in- wheel motor having an inner stationary portion (the stator), and an outer rotating portion (the rotor) that rotates around the stator and drives a wheel directly attached to the rotor. The stator may comprise an inner support structure around which a plurality of magnets having windings are disposed in a circumferential fashion. The rotor circumferentially surrounds the stator, and includes permanent magnets placed at an interval along a surface of the rotor. An intermediate layer between the rotor and the stator is comprised of a bearing that allows movement of the rotor relative to the stator. By attaching a wheel directly to the outer surface of the rotor, a compact and efficient wheel-mounted electrical motor may be provided.
(FR)L'invention porte sur un moteur incorporé à une roue, comprenant une partie fixe intérieure (le stator) et une partie tournante extérieure (le rotor) tournant autour du stator et entraînant une roue directement fixée au rotor. Le stator peut comprendre dans sa structure intérieure, un support autour duquel est disposée d'une manière périphérique une pluralité d'aimants comportant des enroulements. Le rotor entoure de manière périphérique le stator et comprend des aimants permanents disposés selon des intervalles le long de la surface du rotor. Une couche intermédiaire entre le rotor et le stator est composée d'un palier permettant le mouvement du rotor par rapport au stator. Par fixation directe d'une roue sur la surface extérieure du rotor, on peut disposer d'un moteur électrique efficace et compact monté sur la roue.
