ラシレスモータ。[Claims for Utility Model Registration] (1) A rotor comprising a field magnet having a plurality of magnetic poles of N and S poles, and a printed wiring board on a surface facing the field magnet with an axial gap interposed therebetween. An effective conductor that contributes to the generated torque of the armature coil is provided with an insulating substrate such as the like, connected to the lower surface of the insulated substrate at the inner periphery, and formed on the outer periphery extending in the radial direction of the armature coil. A stator yoke is provided, the stator yoke having an extension extending in the radial direction and having a notch between the extensions, the extension of the stator yoke being formed on the upper surface of the insulating substrate. The armature coil is disposed so that an effective conductor portion that contributes to the generated torque of an air-core type armature coil extending in the radial direction is disposed in a position facing the armature coil, and the position detection element is disposed on the upper part of the insulating substrate. A disk-type brushless motor, wherein a terminal of one of the electric circuit components such as the above protrudes from the lower surface of the insulating substrate and faces a notch formed between the extensions of 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) of the utility model registration, which is arranged on the upper surface of an insulating substrate in the same phase position.
