A motor includes a stator and a rotor. The stator carries a plurality of phase windings and the rotor carries a plurality of magnet poles and is connected to a shaft. The stator has a ferromagnetic material defining a yoke and a plurality of teeth and further includes at least one band of electrically conductive material that encompasses at least a portion of one of the teeth or encompasses at least a portion of the yoke in a region between adjacent teeth and is in direct contact with the tooth. The band provides an electrical path between the band and the portion of the tooth or yoke. The band wraps around upper and lower end regions of the portion of the tooth or yoke and extends axially down the opposing side faces of the tooth or yoke. The band is isolated from any external source of motor drive current.
