ELECTRIC MOTOR ROTOR ASSEMBLY HAVING MAGNET RETENTION FEATURE

A rotor assembly includes a rotor core that defines a plurality of cavities and includes a plurality of laminations having annular bodies and stackably arranged to form the rotor core. The plurality of laminations includes a plurality of notch laminations and at least one tab lamination. Each notch lamination defines a plurality of first apertures. Each first aperture has a notch at a portion of the first aperture. The tab lamination defines a plurality of second apertures and includes flexible tabs extending toward the second apertures. The plurality of first apertures and the plurality of second apertures define at least a portion of the plurality of the cavities. A set of notch laminations are stacked with the tab lamination, where the notches of the set of notch laminations align with the flexible tabs of the tab lamination.
