PURPOSE:To obtain a DC brushless motor to be employed in various electric appliances in which downsizing and thinning can be realized. CONSTITUTION:An IC 13 is arranged on a board 12 so that the IC 13 is located substantially in the center of an armature 8. A shield board 14 is placed underneath the board 12 secured with the armature 8 applied with a coil 10 and the armature 8 is disposed oppositely to a tubular rotary permanent magnet 6 thus constituting a DC brushless motor. With such constitution, pattern wiring from the IC 13 can be facilitated and the area of pattern wiring can be reduced with respect to the board and thereby the profile of the board 12 can be reduced resulting in downsizing of DC brushless motor. Furthermore, no restriction is imposed by the coil 10 applied on the armature 8 and thereby a thin DC brushless motor can be realized. |
