20120262012 | ELECTRIC MACHINE MODULE COOLING SYSTEM AND METHOD - Embodiments of the invention provide an electric machine module including a housing. The housing can include an inner surface that defines a machine cavity. In some embodiments, an electric machine can be at least partially positioned within the machine cavity and can include a stator assembly. The stator assembly includes an outer diameter, a stator core, and a stator winding. The stator core can include at least two extended members that can radially extend from axial ends of the stator core. An annular member is coupled to the extended members to define a portion of a coolant jacket. The coolant jacket can be further defined between the annular member, the outer diameter of the stator assembly, and the extended members. The electric machine can be positioned within the housing so that the annular member is immediately adjacent to the inner surface. | 10-18-2012 |
20130043747 | Electric Machine Cooling - Embodiments of the invention provide an electric machine module including an electric machine. The electric machine includes a rotor and a stator assembly. The machine includes an output shaft having a longitudinal axis that is circumscribed by a portion of the rotor. The output shaft may comprise an output shaft channel and the rotor may comprise a rotor channel, and the rotor and the output shaft channels may be in fluid communication. The machine further includes a coolant jacket at least partially within a sleeve member that circumscribes at least a portion of the stator assembly, and at least one pump mounted generally concentrically with respect to the output shaft, that is in fluid communication with the coolant jacket.

20130237361 | REVERSIBLE PLANETARY GEAR ASSEMBLY - A planetary gear assembly includes a ring gear configured for connection to a rotor of an electric motor when in a first position and configured for connection to a housing of the electric motor when in a second position, a sun gear configured for connection to the housing when the ring gear is in the first position and configured for connection to the rotor when the ring gear is in the second position, and a plurality of planet gears configured to mesh with the ring gear and the sun gear. | 09-12-2013 |
20150292392 | THROTTLE CONTROL SYSTEM AND METHOD - A throttle control system for an Otto cycle combustion engine includes a compressor and an electric motor. The compressor is rotatable in both clockwise and counterclockwise directions, and has air inlet and outlet ports, the air outlet port being configured to provide intake air to an air intake system of the engine. The motor, operably connected to the compressor, is configured to operate in a first direction to rotate the compressor clockwise or counterclockwise, and in a second direction to rotate the compressor in a direction reverse of the first direction. An unobstructed air flow passage is disposed between the compressor and the air intake system of the engine. Operation of the motor in the first direction facilitates an increase in air pressure at the air intake system, and operation of the motor in the second direction facilitates a decrease in air pressure at the air intake system. | 10-15-2015 |
20150292397 | TURBOCHARGING SYSTEM AND METHOD - A turbocharger system for a combustion engine includes a turbine, a generator, an electric motor, and a compressor. The turbine is disposed in flow communication with an exhaust flow of the combustion engine productive of exhaust gases, the generator is operably connected to the turbine to produce electrical power in response to operation of the turbine, the compressor is disposed in flow communication with an air intake system of the combustion engine, and the electric motor is operably connected to the compressor to cause operation of the compressor in response to operation of the electric motor. The electric motor is operably connected to the generator via electrical wires configured to deliver electrical power from the generator to the electric motor to cause operation of the electric motor absent a mechanical driving shaft connection between the generator and the electric motor. | 10-15-2015 |
