シレスモータ。[Claims for Utility Model Registration] (1) An electric machine that is equipped with a field magnet as a rotor having a plurality of N-pole and S-pole magnetic poles, and that is adjacent to a surface that faces the field magnet through an axial gap. A stator yoke having an opening angle width comparable to that of a child coil group and an insulating substrate such as a printed wiring board disposed between armature coils that are not disposed adjacent to each other are disposed, and the upper surface of the stator yoke is A plurality of armature coil groups are arranged adjacently so as not to overlap with each other and are arranged to face the field magnet through an axial gap, and a notch or a recess is formed in the stator yoke on the lower surface of the insulating substrate. The stator yoke is arranged so that the electrical circuit components such as a position detection element arranged on the upper part of the insulating substrate are arranged, and the electric circuit components arranged on the upper part of the above insulating board are A disc-type brushless motor in which terminals of any of the components protrude from the lower surface of the insulating substrate and face a notch or a recess formed in the stator yoke. (2) The armature coils are arranged on the insulating substrate so as not to overlap each other, and among the electric circuit components, at least the position sensing element is an effective conductor that contributes to the torque generated by the armature coil. A disk-type brushless motor according to claim 1, which is arranged on the upper surface of an insulating substrate in the same phase position.
