    Abstract: A transmission is provided having an input member, an output member, a plurality of planetary gear sets, a plurality of coupling members and a plurality of torque transmitting devices. One of the plurality of torque transmitting devices is an integrated friction launch clutch. A disconnect clutch is in series relationship with the launch clutch and is configured to disconnect the launch clutch from at least one of the plurality of planetary gear sets. The torque transmitting devices include clutches and brakes actuatable in combinations of two to establish at least ten forward gear ratios and one reverse gear ratio.

    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.
