Abstract: An electric motor includes a stator, a rotor and a rotor carrier radially inside of the rotor non-rotatably fixed to the rotor. The rotor carrier includes an axially extending cylindrical section including an outer circumferential surface having an annular groove formed therein. A method of forming a rotor carrier includes forming, by stamping, a rotor carrier including an axially extending cylindrical section including an outer circumferential surface having annular groove formed therein.

Abstract: A torque converter, including an impeller including an impeller shell with an inner surface, an outer surface facing opposite the inner surface, a first radial portion substantially orthogonal to an axis of rotation for the torque converter, and an axial portion substantially parallel to the axis, extending from the radial portion, forming a radially outmost portion of the impeller shell, and having a first thickness. The shell includes a curved portion including a first protrusion, second and third protrusions radially inward of the first protrusion, a first portion between the radial portion and the first protrusion, and a junction portion connecting the radial portion and the first portion and having a second thickness at least 50 percent greater than the first thickness.

Abstract: A blade with first and second blade tabs extending outwardly from an edge of the blade; and a shell with a first indent and a first slot. The first blade tab is arranged to engage the first indent and the second blade tab is arranged to engage the first slot. In one embodiment, the first indent is arranged radially inward on the shell relative to the first slot. In one embodiment, the first blade tab is affixed to the first indent. In one embodiment, the second blade tab is bent over an outside surface of the turbine shell. In one embodiment, the shell includes a second indent and the blade includes a third blade tab extending outwardly from the edge and at least partially disposed in the second indent. A method of manufacturing a pump or turbine shell for a torque converter.
