摘要：A motor and methods for making and using same. The motor includes a rotor including magnetic poles and a stator comprising a stator core and a winding wound on the stator core. The stator core includes a plurality of stator teeth each including a tooth body and a tooth end faulted at an end of the tooth body, the tooth end comprising first and second arcuate regions facing the rotor. 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 tooth body in such a way as to enable movement of said rotor to initiate in either of two opposite directions relative to said selected tooth body upon energizing the winding.

主权项：1. A motor, comprising: a rotor including magnetic poles; and a stator comprising a stator core and a winding wound on the stator core, the stator core comprising a first stator portion, a second stator portion and a plurality of tooth bodies connected between the first and second stator portions, the first stator portion comprising first and second arcuate regions facing the rotor, wherein the second stator portion defines a gap between each pair of adjacent tooth bodies for facilitating winding the winding on the stator core, a filler chip being filled in the gap after the winding is wound, and 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, the magnetic pole being offset from a selected tooth body in such a way as to enable movement of said rotor to initiate in either of two opposite directions relative to said selected tooth body upon energizing the winding.
