Abstract:
A motor includes a stator and a rotor. The rotor is rotatable about an axis. The rotor includes a core including a plurality of pole segments arranged arcuately about the axis. The rotor further includes a plurality of arcuately arranged magnets alternating arcuately with the pole segments, such that each of the magnets is at least in part interposed between a pair of adjacent pole segments. The plurality of pole segments includes a plurality of first-polarity pole segments having a first polarity and a plurality of second-polarity pole segments having a second polarity that is different than the first polarity. The rotor further includes a connecting element connecting at least some of the first-polarity pole segments to one another without connecting the second-polarity pole segments to the first-polarity pole segments.
