SINGLE-PHASE BRUSHLESS MOTOR |
| 摘要 |
A single phase 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 formed 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. |

1. A single phase 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 plurality of stator teeth each comprising a tooth body and a tooth end formed at an end of the tooth body, the tooth end comprising first and second arcuate regions facing the rotor, 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 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. |
