Abstract: Systems and methods are provided for dynamically modeling and depicting overall emissions of the aviation industry and changes thereto when taking into account, for example, traffic growth and introduction of sustainability strategies, such as new and/or improved technologies, an increase in operational efficiency, and carbon offsets. Using the dynamic tool described herein, users can define scenarios on how to reduce emissions through the introduction of different sustainability strategies, both statically and over time, analyze the impact of those strategies on emissions, and understand the dependencies between select strategies.

Abstract: 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.

Abstract: A bar wound stator assembly includes a connection module attached to a stator core at a weld end of the stator assembly. The connection module provides all required electrical connections to connect shaped plurality of hairpin bar connectors of the stator assembly within a first pole pair of a winding set of conductors. All of the hairpin bar conductors include an identical span. The connection module completes each phase of the winding set, to connect each phase of the winding set to define a connection configuration, e.g., a wye or a delta connection configuration, and to connect the stator assembly to all external connections.

Abstract: 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.
