Abstract
An electric motor is provided. The electric motor comprises a stator and a rotor rotatable about an axis and spaced at least in part radially outside the stator. The rotor includes a plurality of arcuately spaced apart pole segments, a plurality of arcuately spaced apart magnets alternately arranged with the pole segments such that each of the pole segments is positioned between an adjacent pair of the magnets, a rotor can at least in part supporting the pole segments and the magnets, and a plurality of pegs. Each of the pole segments defines an opening therethrough and includes a generally arcuately extending wall structure positioned radially outside of and at least in part defining the opening. Each of the pegs extends through a corresponding one of the openings to secure a corresponding one of the pole segments relative to the can.
