1. A stator, comprising:

  • a first stator portion including first and second arcuate regions for facing a rotor including one or more magnetic poles and being concentrically arranged with the first stator portion relative to a central axis, the central axis being a common center of the first and second arcuate regions; and

    one or more winding portions for being wound with a winding extending radially from the first stator portion away from the central axis,wherein, when the winding is not energized, a first magnetic coupling between said first arcuate region and a selected magnetic pole of the rotor is greater than a second magnetic coupling between said second arcuate region and the selected magnetic pole, a selected winding portion being angularly offset from said first arcuate region in such a way as to enable movement of the rotor to initiate in either of two opposite directions relative to said selected winding portion upon energizing the winding.
