Abstract
A motor and methods for making and using same. The motor includes a stator having a first stator portion with first and second arcuate regions. The arcuate regions can receive a rotor with a magnetic pole and being concentrically arranged with the stator relative to a central axis. The stator can have one or more winding portions for being wound with a winding and extending from the first stator portion opposite the arcuate regions. When the winding is not energized, a first magnetic coupling between the first arcuate region and a selected magnetic pole is greater than a second magnetic coupling between the second arcuate region and the selected magnetic pole. A selected winding portion is angularly offset from the first arcuate region to advantageously enable movement of the rotor to initiate in either of two opposite directions relative to the selected winding portion when the winding is energized.
