Abstract
The present disclosure includes a rotor core assembly for an electric motor. The rotor core assembly includes a plurality of laminations secured together. A center bore is defined by the plurality of laminations. A longitudinal axis of the rotor core assembly extends along an axial center of the center bore. A carbon fiber sleeve surrounds the plurality of laminations. Magnet slots are defined by the plurality of laminations. The magnet slots extend parallel to the longitudinal axis. Magnets are seated in the magnet slots. Reinforcing bores are defined by, and extend across, the plurality of laminations. Reinforcing members are seated in the reinforcing bores.
