ラシレスフアンモータ。 A field magnet having a plurality of N and S magnetic poles is provided as a rotor, and a stator yoke is arranged in the armature coil arrangement part of the motor in the bushless fan motor case through an axial gap between the field magnet and the field magnet. one or more air-core armature coil groups are disposed in a position facing the field magnet of the stator yoke so as not to overlap each other, and an effective conductor portion contributes to the torque generated by the armature coil. A notch such as a small hole is formed at a stator yoke position that is in phase with the stator yoke, a printed wiring board is arranged at the bottom of the stator yoke, and electric components for a drive circuit including a position detection element are arranged on the printed wiring board. and a disk type brushless fan motor having an axial gap type and coreless structure, in which a position detection element disposed on the printed wiring board is passed through a cutout such as a small hole formed in the stator yoke.
