Abstract
A rotor for an electric motor includes a core, a plurality of magnets, and a magnet retention cap. The core is rotatable about an axis and defines a plurality of magnet-receiving slots. Each of the magnets is received in a respective one of the magnet-receiving slots. The magnet retention cap is fixed relative to the core and includes a resiliently deformable magnet retention element configured to restrict axial movement of the magnets relative to the core.
