摘要： An electric machine includes a plurality of planar laminations stacked to form an electrical steel rotor having openings defining magnet pockets and adjacent inner side pockets. The adjacent inner side pockets define a center bridge therebetween and have blasted surface portions such that compressive stress layers are induced along edges of the center bridge to strengthen the center bridge.

摘要： An electric machine rotor including a first stamped rotor lamination and a first stamped sheet of a material different than the first stamped rotor lamination is provided. The first stamped rotor lamination may define a pair of magnet pockets. The first stamped sheet may be coplanar with and scarf jointed to the first stamped rotor lamination to define a center bridge between the magnet pockets that has a magnetic permeability less than, and a mechanical strength greater than, the first stamped rotor lamination. The rotor may further include a second stamped sheet of a material different than the first stamped rotor lamination coplanar with and scarf jointed to the first stamped rotor lamination to define a top bridge adjacent to one of the magnet pockets at a perimeter of the rotor that has a magnetic permeability less than, and a mechanical strength greater than, the first stamped rotor lamination.

摘要： A method of forming a magnet is provided. The method includes disposing an anisotropic magnetic powder and a binder within a bed, the anisotropic magnetic powder having a defined magnetization direction. An energy beam selectively melts the binder such that the anisotropic magnetic powder forms a permanent magnet with the defined magnetization direction. The energy beam is a laser beam, a microwave beam and the like.

摘要： An electric machine includes a stator core defining slots and a first hairpin assembly installed in the stator core. The first hairpin assembly includes first and second same hairpins, each having first and second ends and separately coated to have first and second outer coating surfaces, respectively. The hairpin assembly is in first and second ones of the slots such that the first and second outer surfaces are touching. A weld material joins the first ends and another weld material joins the second ends.

摘要： An automotive motor includes a stator and a rotor disposed within the stator. The automotive motor also includes an endplate attached to the rotor that defines a coolant exit hole, an outer edge, and an array of staggered raised flow disruptors disposed radially between the coolant exit hole and outer edge. The array disrupts flow of coolant as the coolant travels from the coolant exit hole along a surface of the endplate toward the outer edge.

摘要： A method for printing a three-dimensional (3D) article is provided by the present disclosure. The method includes induction heating, by an induction head assembly, a magnetic material to form an alloy melt. The induction head assembly includes a nozzle and an induction heater that heats the magnetic material. The method further includes including the alloy melt from the nozzle onto a base, and tracing a predetermined pattern on the base with the alloy melt to form a three-dimensional article.

摘要： An inductor that is configured to store energy in a magnetic field includes a wire and a core. The wire is configured to deliver electrical current to the inductor to generate the magnetic field. The core is disposed radially about the wire. The core comprises magnetic particles that are suspended in a non-magnetic matrix. The magnetic particles are arranged such that a magnetic permeability of the core increases in a direction that extends radially outward from the wire along a cross-sectional area of the magnetic core from a first region that is adjacent to the wire to a second region that is adjacent to an outer periphery of the magnetic core.
