    Abstract: A vehicle is powered by an electric linear induction motor (LIM) in at least one of the vehicle wheels and the height from the ground and/or wheelbase changed by the wheel structure and its connection to the vehicle chassis. The LIM is disposed radially outwardly from the wheel axis of rotation and comprises a stator having an electrically energizable propulsion coil circumposed by a rotor. A stator shaft connects the stator to the vehicle chassis and the stator and associated shaft are fixedly-connected and angularly orbited about the inner diameter of the rotor whereby to change the height of the vehicle chassis from the ground or the wheelbase of the vehicle. The rotor is supported for rotation about the stator by bearings, or by magnetic levitation, as provided by a ring of permanent magnets in the rotor disposed in juxtaposition with an electrically energizable levitation coil in the stator.

    Abstract: An electromotive machine having a stator element and a rotor element, the stator element including at least one set of four toroidally shaped electromagnetic members, the electromagnetic members arranged along an arc a predetermined distance apart defining a stator arc length. Each of the members has a slot, and the rotor element includes a disc adapted to pass through the slots. The disc contains a plurality of permanent magnet members spaced side by side about a periphery thereof and arranged so as to have alternating north-south polarities. These permanent magnet members are sized and spaced such that within the stator arc length the ratio of stator members to permanent magnet members is about four to six. Thc electromagnetic members are energized in a four phase push-pull fashion to create high torque and smooth operation.

    Abstract: A driving or driven wheel assembly for a vehicle includes a wheel having a rotor which has an inner surface coaxial with the axis of rotation of the wheel and a stator which form part of the axle structure. A portion of the stator is encircled by the rotor and an electrical coil connected to a source of electrical energy for creating an electromagnetic force to rotate the rotor relative to the stator. The stator is coupled to the wheel radially outwardly from the axis of rotation and orbits about the inner surface of the rotor via a trunnions mounted shaft. The shaft is driven into orbiting rotation and is coupled to the wheel chassis such that as the shaft orbits the chassis moves in response thereto while maintaining its spatial relation thereto.

    Abstract: A sensorless switched reluctance machine includes a stator with a plurality of circumferentially-spaced stator segment assemblies that include salient stator poles and inter-polar stator slots. Each of the stator segment assemblies includes a stack of stator plates forming a stator segment core, an end cap assembly, and winding wire wound around the stator segment core and the end cap assembly. The rotor defines a plurality of rotor poles. The rotor tends to rotate relative to the stator to a rotational position that maximizes the inductance of an energized winding. A sensorless drive circuit derives rotor position and energizes the winding wire around the stator segment assemblies based on the derived rotor position. Each stator plate includes a first radially outer rim section and a tooth section that extends radially inwardly from a first center portion of the first radially outer rim section.

    Abstract: With an electric motor formed according to a prior art, there is a relatively large amount of magnetic flux leaking between an armature and a secondary, resulting in a problem that an electric current is large but a desired output is small. In addition, since a magnetic attraction acts only in one direction between the armature and the secondary, there is a relatively large load on the support structures of the secondary, causing a distortion in the motor structure and some other disadvantages. In order to solve the above problems, the present invention provides an improved electric motor comprising an armature having a core formed by a magnetic material and having a coil wound around the core; and a secondary disposed within the armature with a clearance formed therebetween and supported to be relatively movable with respect to the armature.

    Abstract: A method of controlling a dual wound synchronous machine (DWSM) includes: determining virtual current commands based on a current command associated with each of two winding sets of the DWSM; determining virtual half-motor currents by applying a mathematical transformation on measured output currents; determining half-motor difference currents based on differences between the corresponding virtual current command and the virtual half-motor current; calculating forward path voltage commands based on the corresponding difference currents and using first and second gain factors; determining feedback voltage commands by applying third and fourth gain factors to the virtual half-motor currents; determining virtual final voltage commands based on the corresponding forward path and feedback voltage commands; determining final voltage commands by applying a second mathematical transformation to the virtual final voltage commands; commanding, based on the final voltage commands, inverters to apply corresponding voltages to the two winding sets and thereby generating the output currents.
