Abstract
A rotor assembly for an electric motor includes a rotor core and a plurality of magnets. The rotor core defines a rotation axis. Each of the magnets includes a magnet stem portion and a magnet arm portion. The magnet stem portion extends radially relative to the rotational axis to present a radially outermost stem end. The magnet arm portion is located at least in part radially outward from the stem end. In addition, the magnet arm portion extends circumferentially in opposite directions relative to the magnet stem portion.
