| 摘要 |
A motor may include a rotor having a magnet and a stator having a stator core and a coil. The stator core is provided with salient poles, including a predetermined salient pole, separately formed in the circumferential direction, the salient poles are protruded to an inner side and face the magnet through a gap space, and the predetermined salient pole is wound around with the coil through a coil bobbin. The stator core is provided with a connecting part which connects end parts of the salient poles. The coil bobbin is provided with a body part around which the coil is wound and an insertion hole formed in the body part and into which the predetermined salient pole is inserted. The coil bobbin and the stator core engage with the other to restrain displacement of the coil bobbin to the inner side. |

1. A motor comprising:
a rotor comprising a magnet whose peripheral face is alternately magnetized in an “S”-pole and an “N”-pole in a circumferential direction; and a stator comprising a stator core and a coil; wherein the stator core is provided with a plurality of salient poles, including a predetermined salient pole, which are separately formed in the circumferential direction, the plurality of the salient poles being protruded to an inner side in a radial direction and facing the peripheral face of the magnet through a gap space, the predetermined salient pole being wound around with the coil through a coil bobbin; wherein the stator core is provided with a connecting part which connects end parts on an outer side in the radial direction of the plurality of the salient poles; wherein the coil bobbin is provided with a body part around which the coil is wound and a salient pole insertion hole which is formed in the body part and into which the predetermined salient pole is inserted; and wherein one of the coil bobbin and the stator core is formed with an engaging part which is engaged with another of the coil bobbin and the stator core to restrain displacement of the coil bobbin to the inner side in the radial direction. |
