摘要： A hub assembly for an electric machine includes a rotor hub and a machine rotor. Rotation of the machine rotor generates an electromagnetic (EM) field. The hub assembly includes a resolver rotor that encodes an angular position of the machine rotor as a set of resolver signals. An EM field barrier ring between the resolver rotor and the rotor hub adds a magnetic barrier between the machine rotor and the resolver rotor to reduce noise in the resolver signals. The resolver rotor may be bonded to the EM field barrier ring. The EM field barrier ring may have an L-shaped cross section, and may be press-fitted into a pocket of the rotor hub. A vehicle includes a transmission having an input member and an electric machine having a rotor shaft connected to the input member of the transmission. The electric machine includes the hub assembly noted above.

摘要： An oil-cooled motor/generator for an automotive powertrain located outside of the transmission is provided, such as a BAS motor/generator. The motor/generator may have a stator, a rotor circumscribed by the stator, and a motor shaft on which the rotor is mounted for rotation. A housing assembly may surround the stator and the rotor, with a bearing positioned between the housing assembly and the motor shaft. A flow control member may at least partially circumscribe the rotor axially adjacent the stator. A bearing retainer may be positioned axially adjacent the bearing. A rotor end ring may be axially adjacent the rotor. The housing assembly may have an inlet configured to receive cooling oil. The housing assembly, the flow control member, the bearing retainer and the rotor end ring may be configured to distribute the cooling oil from the inlet to cool the stator, the rotor and the bearing.

摘要： An electric machine is provided with a rotor core rotatable about a central axis. A first end ring is operatively connected to one end of the rotor core. A first housing component at least partially encloses the rotor core. At least one first rotor fin extends from the first end ring in a first direction which may be substantially parallel to the central axis. At least one first housing fin extends from the first housing component in a second direction that is substantially opposite to the first direction. The first rotor and housing fins extend circumferentially around the central axis. The first rotor fin and the first housing fin are configured to interleave, thereby enhancing heat transfer between the first rotor and housing fin, and cooling the rotor core.

摘要： A hybrid transmission having an input member, an output member, and a single motor/generator is characterized by a plurality of fixed-ratio modes of operation and at least one electrically variable mode of operation. In the fixed-ratio modes of operation, the speed ratio between the input member and the output member is independent of the speed of the motor/generator. In the electrically variable mode of operation, the speed ratio between the input member and the output member is dependent upon the speed of the motor/generator.

摘要： Methods, systems, and vehicles are provided pertaining to the determination of a temperature of a vehicle motor having an ignition when the ignition is turned on following a period of time in which the ignition had been turned off. A memory stores a function having a boundary condition that comprises a prior temperature from when the ignition was turned off. A processor is coupled to the memory. The processor is configured to determine an amount of time for which the ignition has been turned on and determine the temperature of the motor using the function if the amount of time for which the ignition has been turned on is less than a predetermined threshold.
