摘要： An electric machine produces motor torque having continuously variable magnetic and reluctance torque components. The electric machine includes stator and rotor assemblies. Different ends of the rotor hub have different average magnetic field strengths, with the second field strength at one end being weaker than the other. The rotor hub translates along the rotor shaft to vary the magnetic and reluctance torque components at different speed and torque operating points of the electric machine. A vehicle includes the machine, a transmission, a load, and a controller executing a method for controlling the axial position of the rotor hub. The method may include determining the speed and a torque of the electric machine, determining a corresponding desired axial position of a rotor hub, and translating the rotor hub to the desired axial position.

摘要： An electric power assembly for a vehicle is disclosed. An electric motor includes a stator and a rotor being rotatable about a pivot axis relative to the stator. An inverter is coupled to the electric motor and includes a power switching device that outputs an electrical signal from the inverter at a first frequency and having interference at a second frequency. The second frequency is a byproduct of the electrical signal creating the first frequency. The stator is electrically connected to the inverter to receive the first frequency such that the stator produces a first magnetic field. A frequency filter is attached to the rotor and directs the portion of the electrical signal having the second frequency to the rotor such that the rotor produces a second magnetic field that interacts with the first magnetic field to rotate the rotor about the pivot axis relative to the stator.

摘要： An apparatus for providing a coolant to a stator and a rotor of an electric motor in a vehicle having a coolant pump is provided. The apparatus includes a base defining a plurality of first openings through at least one of which the coolant is flowable to the stator. The apparatus also includes at least one wall extending from the base to define a cavity configured to receive the coolant from the coolant pump. The apparatus further includes at least one first raised member within the cavity that extends from the base. The at least one first raised member defines at least one second opening substantially aligned with one of the first openings to form a first passageway through which the coolant is flowable to the rotor. The apparatus may be located above the electric motor such that the coolant is flowable by gravity to the stator and/or the rotor.

摘要： A method for operating an electric machine of a ground vehicle includes periodically determining an aging parameter based upon a temperature of the electric machine and periodically determining a short-term aging effect based upon the periodically determined aging parameter. A long-term aging effect is determined based upon the short-term aging effect. A short-term temperature adjustment is determined based upon the short-term aging effect and a long-term temperature adjustment is determined based upon the long-term aging effect. A temperature-based derated motor torque is determined based upon the long-term temperature adjustment and the short-term temperature adjustment. Operation of the electric machine is controlled responsive to an operator command for torque based upon the temperature-based derated motor torque.

摘要： An electric device and a stator assembly for the electric device includes a stator core defining a plurality of slots spaced from each other. The stator assembly includes a plurality of bar conductors disposed in each of the slots and arranged to present a first winding path, a second winding path and a third winding path. A first set of the bar conductors of the first, second and third winding paths are configured to receive current in a parallel circuit arrangement. The stator assembly also includes a plurality of electrical jumpers electrically connected to a predetermined number of the bar conductors such that an amount of current flowing through the first winding path and the third winding path is substantially the same and an amount of current flowing through the second winding path is different from the amount of current flowing through the first and third winding paths.
