    Abstract: A rotor assembly has a rotor including a plurality of laminations each defining a plurality of poles arranged such that values of a pair of angles corresponding to each of the poles and defined between a magnetic axis of the pole and respective interpolar axes adjacent thereto are different. The values of the pairs define a repeating sequence around the lamination. The angles opposite an axis of rotation of the rotor are equal.

    Abstract: A hybrid powertrain utilizes a motor with a permanent magnet rotor. The rotor is formed by inserting parallelepiped magnets into slots. To reduce the likelihood of demagnetization, the net magnetization of each magnet is oriented parallel to a sidewards surface of the magnet and not perpendicular to an outwards surface of the magnet. The magnets may be arranged in multiple rows. The magnets in each row may be perpendicular to a rotor radial or diagonal to a rotor diagonal.

    Abstract: An electric machine rotor includes a lamination configured to rotate about a central axis and a plurality of pairs of permanent magnets. Each pair of permanent magnets is arranged in a V-shaped pattern and affixed within the lamination to create a magnetic field for rotation of the lamination. The lamination also includes an outer periphery spanning circumferentially outside of the permanent magnets, wherein a mass-reduction cutout extends through the lamination nested within in a V-shape defined by the permanent magnets adjacent to an outer surface of the rotor. The lamination further includes a stress-reduction slot that extends through the outer periphery of the rotor.

    Abstract: A method of forming an electric machine lamination includes punching a sheet having a first composition to form a cavity and a compressed region at a perimeter of the cavity. The method further includes depositing, within the cavity and on the compressed region, a deposit material having a second composition different than the first composition. The method further includes scanning a beam along the deposit material to form a bound material within the cavity and on the compressed region.
