Abstract
An electric machine includes a stack of interlocked rotor core laminations, individual rotor core laminations of the interlocked rotor core laminations including a mortise extending therein and an integrally-formed tenon extending therefrom, wherein the tenons interface with the mortises to interlock adjacent rotor core laminations.
Claims6
An electric machine comprising:
- a stack of interlocked rotor core laminations, individual rotor core laminations of the interlocked rotor core laminations including a mortise extending therein and an integrally-formed tenon extending therefrom, wherein the tenons interface with the mortises to interlock adjacent rotor core laminations,
- wherein a first individual rotor core lamination of the stack includes a first mortise having a depth extending into the first individual rotor core lamination and a second individual rotor core lamination of the stack includes a first integrally-formed tenon having a height extending therefrom, wherein the height of the first integrally-formed tenon corresponds to the depth of the first mortise,
- wherein the second individual rotor core lamination includes a second mortise having the depth extending into the second individual rotor core lamination and a third individual rotor core lamination of the stack includes a second integrally-formed tenon having the height extending therefrom to engage with the second mortise, and
- wherein the first integrally-formed tenon and the second mortise are on opposite surfaces of the second individual rotor core lamination.
