  • Rotor assembly including an end ring staked with curved indentations and method thereof
    Patent number: 11088581
    Abstract: A rotor assembly for an electric motor, including: a rotor carrier hub; a rotor radially disposed about the rotor carrier hub; and an annular end ring. The rotor carrier hub includes: an axis of rotation; an annular outer surface facing in a first axial direction parallel to the axis of rotation; a circumferentially disposed outer surface; a curved indentation in the annular outer surface; and a protrusion extending beyond the circumferentially disposed outer surface in a radially outward direction orthogonal to the axis of rotation and radially aligned with the curved indentation such that a line, in the radially outward direction, passes through the curved indentation and the protrusion. The end ring is in contact with the circumferentially disposed outer surface of the rotor carrier hub and the protrusion. The protrusion blocks displacement of the rotor in the first axial direction.
