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 method of prioritizing power output of first and second power-sources in a vehicle includes identifying, via a controller communicating with a satellite, the vehicle's position on a specific road course. The method also includes receiving a request for total amount of power from both power-sources and determining first power-source power and available second power-source target maximum power based on the vehicle position. The method also includes determining, based on the vehicle position, a minimum energy reserve of a source configured to energize the second power-source and available second power-source power based on the determined reserve. The method also includes subtracting the first power-source power from the requested total amount of power to determine a requested second power-source power. Furthermore, the method includes comparing the available and the requested second power-source power and generating the smaller power value to minimize the time for the vehicle to traverse the road course.
