Motor and method for using and making the same
First Claim
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.

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.

11. A motor, comprising:
-
a rotor including one or more magnetic poles; and a first stator portion concentrically arranged with the rotor and including first and second arcuate regions facing the rotor, and one or more winding portions opposite said arcuate regions and extending radially from said first stator portion for being wound with a winding, a central axis of the rotor being a common center of the first and second arcuate regions, wherein, when the winding is not energized, a first magnetic coupling between said first arcuate region and a selected magnetic pole of said rotor is greater than a second magnetic coupling between said second arcuate region and the selected magnetic pole, said first arcuate region being offset from a selected winding portion in such a way as to enable movement of said rotor to initiate in either of two opposite directions relative to said selected winding portion upon energizing the winding. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
