BRUSHLESS MOTOR, ELECTRICAL ACTUATOR AND DRIVING DEVICE FOR OPENING AND CLOSING BODY FOR VEHICLE |
| 摘要 |
A brushless motor includes a magnet rotor including a rotary shaft to be rotatable about the rotary shaft, a stator including plural teeth facing against the magnet rotor, plural drive coils being wound around the teeth and being supplied with a three-phase drive power to rotate the magnet rotor, and plural holding coils being wound around the teeth and including an independently-arranged power supply line, in which the holding coils are arranged to generate an electromagnetic attractive force to maintain the magnet rotor at a rotational position where ends of the teeth around which the holding coils are wound and a magnetic pole of the magnet rotor are configured to directly face against one another by supplying electricity to the holding coils via the power supply line. |

1. A brushless motor, comprising:
a magnet rotor including a rotary shaft to be rotatable about the rotary shaft; a stator including a plurality of teeth facing against the magnet rotor; a plurality of drive coils being wound around the teeth and being supplied with a three-phase drive power to rotate the magnet rotor; and a plurality of holding coils being wound around the teeth and including an independently-arranged power supply line, wherein the holding coils are arranged to generate an electromagnetic attractive force to maintain the magnet rotor at a rotational position where ends of the teeth around which the holding coils are wound and a magnetic pole of the magnet rotor are configured to directly face against one another by supplying electricity to the holding coils via the power supply line. |
