    Abstract: A transmission assembly has an integrated torque machine including a torque machine stator and a torque machine rotor. The torque machine rotor includes at least one set of rotor magnets. An integrated rotational position sensor is configured to monitor rotational position of the torque machine rotor in relation to the torque machine stator. The integrated rotational position sensor includes a sensor rotor element and a sensor stator element. The sensor rotor element includes at least one set of sensor rotor magnets. The sensor rotor element is positioned such that the at least one set of sensor rotor magnets are aligned with respect to a rotor pole of the at least one set of rotor magnets of the torque machine rotor. The sensor stator element is positioned such that the sensor stator element is aligned with a magnetic axis of the torque machine stator.

    Abstract: Apparatus for voltage stabilization in a vehicle includes a battery distribution module having a load module managing electrical power to one or more auxiliary loads, a first switch coupling a starter motor and an ESD to the load module only when closed, a second switch coupling an auxiliary ESD to the load module only when closed, and a controller integrated with a PC board attached to the first and second switch devices. The controller is configured to control opening and closing of the first and second switches based on at least one of a plurality of signals received by the controller. The primary ESD is electrically coupled a primary fuse terminal of the battery distribution module which electrically couples the primary ESD to a second terminal of the first switch and the starter motor. The auxiliary ESD is electrically coupled to an auxiliary fuse terminal of the battery distribution module which electrically couples a first terminal of the second switch to the auxiliary ESD.

    Abstract: A rotor of a permanent magnet synchronous machine includes a rotor core structure. A first set of apertures are formed in a first radial layer of the rotor core structure having a first set of permanent magnets disposed therein forming respective poles. A second set of apertures formed in a second radial layer of the rotor core structure of each pole. A third set of apertures is formed in a third radial layer of the rotor core structure. A second set of permanent magnets is inserted within the third set of apertures. A plurality of bridges each extends across a respective side of each of the third set of apertures in the third radial layer. The plurality of bridges provides structural support of the rotor core structure when operating. The plurality of bridges are integrally formed as single-piece laminations.
