Title:
MOTOR IN WHEEL ELECTRIC DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO2002094603
Kind Code:
A3
Abstract:
A vehicle (10) is powered by an electric linear induction motor (LIM) in at least one of the vehicle wheels (24) and the height from the ground and/or wheelbase changed by the wheel structure (24) and its connection to the vehicle chassis (12). The LIM is disposed radially outwardly from the wheel axis of rotation and comprises a stator (34) having an electrically energizable propulsion coil (48) circumposed by a rotor (30). A stator shaft (36) connects the stator (34) to the vehicle chassis (12) and the stator (34) and associated shaft (36) are fixedly-connected and angularly orbited about the inner diameter of the rotor (30) whereby to change the height of the vehicle chassis (12) from the ground or the wheelbase of the vehicle (10). The rotor (30) is supported for rotation about the stator (34) by bearings (54), or by magnetic levitation, as provided by a ring of permanent magnets (56) in the rotor (30) disposed in juxtaposition with an electrically energizable levitation coil (58) in the stator (34).
