ABSTRACT:
A disk-type brushless fan motor comprises a stator yoke having a suitable cutaway portion formed therein for allowing generation of a cogging torque to allow self-starting of a magnet rotor of the motor. A printed circuit board underlies the stator yoke, and a position detecting element is located on a face of the printed circuit board opposing to the cutaway portion of the stator yoke. The printed circuit board has one or more small cutaway portions formed along an outer periphery thereof within a range of the cutaway portion of the stator yoke, and opposite leads or terminals of a pair of armature coils located on the stator yoke extend through the cutaway portions of the printed circuit board in order to establish electric connection to electric parts located on the rear side of the printed circuit board.
