Abstract: Permanent magnets and methods of making the same are disclosed herein. The permanent magnets include a 3D-printed, i.e., additively manufactured, framework and an infiltrate such that there is a discrete magnetic phase and a discrete non-magnetic phase or two discrete magnetic phases. The infiltrate may provide superior strength, elasticity or magnetic properties.

Abstract: An electric machine includes a stator and a rotor. The stator has a yoke fitted over a ring that has a plurality of teeth with gaps therebetween for fitting metal windings. The ring of teeth has an inner circumference that is closed and to connect the teeth, and an outer circumference with open gaps or slots between the teeth. The metal windings are fitted through the open outer circumference. Regions of the closed inner circumference between the teeth are treated such that the region's magnetic permeability is reduced relative to the remainder of the stator. The reduction in magnetic permeability provides a magnetic flux barrier between the teeth.

Abstract: A vehicle-based microgrid includes a controller and a vehicle having a power source and a network. The controller is operable to operate the power source to supply power to the network for consumption by loads on the network and to adjust operation of the power source in supplying power to the network upon a battery source being added to the network. The power source may be (i) a traction battery, (ii) an electrical generator, or (iii) a non-traction battery. The battery source may be (i) a battery that is on-board the vehicle and that is not the power source or (ii) a battery that is off board the vehicle.

Abstract: A vehicle electric machine assembly including a stator core and a terminal block is provided. The stator core includes one or more three-phase terminals connected to end windings. The terminal block includes a connector for each of the three-phase terminals. A portion of the end windings extending from the stator core, the three-phase terminals, and the terminal block are overmolded as a single unit such that a portion of each of the connectors is exposed for connection to an inverter. The terminal block may further include one or more threaded apertures, each sized to receive a threaded stud to facilitate an electrical connection between one of the one or more three-phase terminals and the inverter. Each of the one or more three-phase terminals may extend axially along an axis substantially parallel to a central axis of a rotor disposed within a cavity defined by the stator core.

Abstract: An electric machine includes a rotor and a stator. The rotor is configured to generate rotational motion. The stator is disposed radially about the rotor. The stator has a core and windings. The core defines a first array of orifices about an inner diameter of the core and a second array of orifices radially outward from the first array of orifices. The windings are disposed within the first array of orifices. A magnetic material is configured to advance into and retract from the second array of orifices to adjust a magnetic flux within an airgap defined between the rotor and the stator.

Abstract: A stator for an electric machine is formed in stratified layer forming a core having axial slots, and a plurality of hurdle-shaped conductors. Each conductor includes first and second uprights disposed in the slots, and a bridge connecting the uprights and extending circumferentially over a core end surface. The first upright is radially closer to a core central axis than the second upright. Each bridge steps radially outward from the first upright to the second upright. Radially adjacent bridges nest next to one another without crossing over one another. A junction between the first end of the bridge and the first upright defines a radially outward-facing ledge, and a junction between the second end and the second upright defines a radially inward-facing ledge. Each bridge passes over the outward-facing ledge of its radially inwardly adjacent conductor and passing over the inward-facing ledge of its radially outward adjacent conductor.

Abstract: Methods for tuning properties of electric machines are disclosed. A method for reducing core loss in an electric machine includes punching a plurality of laminations from one or more electrical steel sheets that results in one or more cut edges. The method further includes assembling the laminations into a core such that an outer perimeter surface of the core is defined by the cut edges. The method further includes peening the outer perimeter surface to remove residual stresses.

Abstract: A vehicle system includes a converter, outlets, and a switching arrangement electrically between the outlets and the converter. A controller is programmed to, responsive to a first request, operate the switching arrangement to electrically connect a line and a neutral to a first outlet and operate the converter to output single-phase power to the first outlet. Responsive to a second request, the controller is configured to operate the switching arrangement to electrically connect a plurality of lines and not the neutral to a second outlet, and operate the converter to output three-phase power to the second outlet.
