    Abstract: A permanent magnet electric machine (PM machine) for a vehicle or other system includes a rotor assembly, fixed permanent magnets, a stator, an actuator, and one or more repositionable/moveable flux-shunting elements. The flux-shunting element is repositioned to control flux at specific operating points of the PM machine. The rotor assembly has a rotor coaxially surrounding and coupled to a rotor shaft. The permanent magnets are mounted to or in the rotor, and the moveable flux-shunting element is positioned between the rotor shaft and a respective one of the permanent magnets. Inboard and outboard ends of each respective permanent magnet may be oriented toward the rotor shaft and stator, respectively. The actuator selectively positions the moveable flux-shunting element at one or more operating points of the PM machine to vary reluctance in a magnetic circuit formed by the stator and rotor assembly.

    Abstract: A permanent magnet electric machine (PM machine) includes a rotor with rotatable magnets and a stator defining an air gap with the rotor. An actuator rotates the rotatable magnets at predetermined operating points through an angular distance sufficient for changing magnetic pole orientations of the rotatable magnets, and thus modifies magnetic flux linkage with stator windings across the air gap. Fixed magnets may be arranged around a circumference of the rotor. The actuator may be actively or passively driven. Flux-shunting elements are optionally disposed in the rotor to further modify the flux linkage. A gear set connected to torque transfer elements may be driven by the actuator to rotate the rotatable magnets. A vehicle includes drive wheels, a transmission, and the PM machine. A method controls magnetic flux linkage in the PM machine noted above.

    Abstract: A system is provided for latching and draining a torque transmitting device. The system may include a clutch feed channel having an inlet portion and a clutch portion. The inlet portion is configured to provide hydraulic fluid from a pressurized source to the clutch portion. The clutch portion is configured to provide hydraulic fluid to a torque transmitting device. An inlet valve connects the inlet portion of the clutch feed channel to the clutch portion of the clutch feed channel. The inlet valve is configured to open to allow the hydraulic fluid to flow from the inlet portion to the clutch portion when the torque transmitting device is engaged. The inlet valve is configured to close and to trap hydraulic fluid within the torque transmitting device when the torque transmitting device is not actively pressurized. A multispeed transmission is also provided.
