Abstract
A brushless motor includes a stator disposed along an axis and a rotor disposed radially inward from the stator. The rotor includes a core, a plurality of first magnets and a plurality of second magnets configured to have opposite poles relative to the plurality of first magnets. The plurality of first and second magnets may each have a substantially rectangular cross-section and are in contact with a substantially flat surface carried by the core that faces radially outward.
