Abstract
A lamination for an electrical machine lamination stack includes a body defining a plurality of winding slots on an inner diameter thereof and at least one inner diameter cleat aperture defined by the body configured to receive a cleat in an unlocked position and to interfere with the cleat when the cleat is transitioned to a locked position within the inner diameter cleat aperture such that a plurality of laminations can be stacked and locked together by the cleat.
Claims17
A lamination for an electrical machine lamination stack, comprising:
- a body defining a plurality of winding slots on an inner diameter thereof;
- and
- at least one inner diameter cleat aperture defined by the body configured to receive a cleat in an unlocked position wherein the cleat is curved or angled and to interfere with the cleat when the cleat is transitioned to a locked position within the inner diameter cleat aperture wherein the cleat is flatter than in the unlocked position such that a plurality of laminations can be stacked and locked together by the cleat, wherein the cleat aperture is formed within the winding slot, wherein the cleat aperture is not open to the outer diameter of the body, wherein the cleat aperture is formed at a radially outward portion of the one or more winding slots.
An electrical machine core, comprising:
- a plurality of laminations stacked together, each lamination including:
- a body defining a plurality of winding slots on an inner diameter thereof;
- and
- at least one inner diameter cleat aperture defined by the body configured to receive a cleat in an unlocked position wherein the cleat is curved or angled and to interfere with the cleat in a locked position wherein the cleat is flatter than in the unlocked position such that a plurality of laminations can be stacked and locked together by the cleat, wherein the cleat aperture is formed within the winding slot, wherein the cleat aperture is not open to the outer diameter of the body, wherein the cleat aperture is formed at a radially outward portion of the one or more winding slots.
