Abstract: A method for forming a component of an electric motor through additive manufacturing. The method includes dispensing a powdered magnetically-susceptible material, a binder and an insulating material in a rotary manner to form discrete layers; and compacting the powdered magnetically-susceptible material and curing the binder while the first layers are being formed. A plurality of cooling apertures are formed through the first and second layers. The cooling apertures cooperate to form a plurality of cooling channels that are formed axially through the component of the electric motor.

Abstract: An additive manufacturing system may include a table, a supporting structure, a first powder dispenser, and a second powder dispenser. The table is rotatable about a first rotational axis. The supporting structure may be mounted for movement relative to the table. The first powder dispenser may be mounted to the supporting structure and may extend radially across the table. The first powder dispenser includes a first outlet disposed vertically above the table. The second powder dispenser may be mounted to the supporting structure and may extend radially across the table. The second powder dispenser includes a second outlet disposed vertically above the table. The table is rotatable about the first rotational axis relative to the supporting structure and the first and second powder dispensers. The first and second powder dispensers may be movable with the supporting structure relative to the table in a direction parallel to the first rotational axis.

Abstract: A method for forming a shaft assembly includes: providing a shaft structure, the shaft structure comprising a shaft and a universal joint member that is coupled to an end of the shaft; inserting a weight member to the shaft structure to form an intermediate assembly, the weight member being formed at least partly from a liquid resin, the intermediate assembly having an initial rotational unbalance; rotating the intermediate assembly about a longitudinal axis of the shaft structure to re-distribute a least a portion of the weight member circumferentially about the shaft structure to at least partly attenuate the initial rotational unbalance; and curing the liquid resin while rotating the intermediate assembly to fix the re-distributed portion of the weight member to the shaft structure to thereby form a balance weight that at least partly attenuates the initial rotational unbalance. A shaft assembly is also provided.

Abstract: A vehicle driveline having a torque transfer device and a fluid circuit for operating the torque transfer device. The fluid circuit has a motor, a pump driven by the motor, an actuator, and a pair of valves. The valves are arranged in the fluid circuit to control fluid circulation within the fluid circuit and can be operated such that fluid pressure in the actuator can be maintained (i.e., to maintain engagement of the torque transfer device) without operating the pump.

Abstract: A G-rotor pump assembly is disclosed. The assembly makes use of a housing having a pump/motor housing portion and a laterally projecting housing portion. An electric motor is disposed within the pump/motor housing portion. A controller has a circuit board with a portion which is positioned within the pump/motor housing portion so as to be generally axially aligned with the electric motor and in proximity to the electric motor. A lower cover is configured to engage with the housing to encapsulate the controller and the electric motor within the housing.

The secondary driveline includes a second coupling that selectively inhibits power transmission through the secondary driveline. The hydraulic pump is configured to operate the first coupling but is powered by a synchronization event in which the second coupling is engaged so as to back drive the PTU output member.
