    Abstract: A rotary electric machine, e.g., a cycloidal reluctance motor, includes a stator having stator teeth connected to a cylindrical stator core, and a rotor having a cylindrical rotor core. The stator core and/or rotor core are constructed of grain-oriented, spirally-wound ferrous material having a circular or annular grain orientation. The stator teeth may be constructed of grain-oriented steel having a linear grain orientation. Notches may be spaced around an inner circumferential surface of the stator core, with each stator tooth engaged with a respective notch. The rotor may be eccentrically positioned radially within the stator. The rotor core may define notches spaced around its outer circumferential surface, with salient rotor projections engaged with a respective rotor notch. The machine in such an embodiment may be a switched reluctance rotor. An electrical system using the machine and a method of manufacturing the machine are also disclosed.

    Abstract: A vehicle includes a vehicle structure that extends along a longitudinal axis. An engine includes a crankshaft that defines a crank axis disposed substantially transverse to the longitudinal axis. A transmission includes an output shaft that defines a transmission output axis substantially parallel with the crank axis. The transmission output axis is disposed nearer the forward end of the vehicle structure than the crank axis. The crank axis is disposed vertically above the transmission output axis a distance of about 140 mm. The engine includes at least one cylinder bore that defines a bore axis disposed perpendicular to and may intersect the crank axis. The bore axis may be angled toward the forward end of the vehicle structure to define an angle between the bore axis and a vertical plane. The angle between the bore axis and the vertical plane may be about 18°.
