Abstract: An electric machine includes a stator with a core having an end face and a plurality of conductors forming windings that extend adjacent to the end face defining end turns having a toroidal outline. The end turns are formed to define at least one channel in the end turns that traverses the end turns for increasing a surface area for fluid contact and directing a flow of fluid along the toroidal surface.

Abstract: A method of forming a power-module assembly includes arranging power stages in a cavity of a container such that the power stages are spaced apart from walls of the container. The method further includes inserting a core between each of the power stages, and installing a manifold on top of the power stages. The method also includes putting resin into the cavity to form a housing of the power-module assembly, and removing the core to reveal coolant chambers between each of the power stages.

Abstract: An electric machine includes a plurality of printed layers arranged to form a stator having an outer periphery and teeth extending radially inward from the outer periphery. Each of the printed layers includes discrete portions of metal and discrete portions of insulation. The discrete portions of insulation define a contiguous network of insulative boundaries separating discrete cells formed by the discrete portions of the metal. A volume of the discrete cells within the outer periphery is greater than a volume of the discrete cells within the teeth such that a reluctance of the teeth is greater than a reluctance of the outer periphery.

Abstract: A method of manufacturing a stator is provided. The method may include stamping steel into laminations each having an inner edge area defining a residual stress associated with a magnetic permeability. The method may also include exposing the laminations to a changing magnetic field such that, for each of the laminations, a density of resulting eddy currents is greatest near the inner edge area to heat the same relative to central areas of the lamination to decrease the residual stress and core loss.

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 encasement of an electric machine of an electrified vehicle is provided. The encasement may include a base sidewall, an inner sidewall, and an outer sidewall. The inner sidewall may extend in a circular pattern about the base sidewall. The outer sidewall may extend from the base sidewall and may be spaced apart from the inner sidewall to define a coolant channel at least partially surrounding end windings of a stator of the electric machine. The base sidewall may define features between the sidewalls to promote turbulence of coolant flowing through the coolant channel. The base sidewall may define a meandering trough between the sidewalls to form a predetermined coolant path relative to a location of the end windings.
