デイスク型ブラシレスモータ。[Claims for Utility Model Registration] (1) A field magnet having a plurality of N and S magnetic poles is provided as a rotor, and an armature coil arrangement portion on the stationary side is provided with an axial gap between the field magnet and the field magnet. An insulating substrate and a stator yoke are disposed on substantially the same plane, two or more air-core armature coil groups are disposed on the upper surface of the stator yoke so as not to overlap each other, and the upper surface of the insulating substrate is disposed on the upper surface of the insulating substrate. A disk-type brushless motor having an axial gap type and coreless structure, in which a position detection element is disposed at the base plate, and a terminal of the position detection element protrudes from the lower surface of the insulating substrate. (2) The stator yoke has a shape with a cutout or recess formed at an appropriate position facing the effective conductor part that contributes to the torque generated by the armature coil or all or a part of the armature coil, and the position can be detected. The element is disposed on the upper surface of an insulating substrate in the same phase position as the effective conductor portion that contributes to the generated torque of the armature coil disposed on the upper surface of the stator yoke, the scope of the utility model registration claim (1) Disc type brushless motor described.
