囲第1項に記載の電動ファン。[Claims for Utility Model Registration] I In a DC brushless motor, four coils are wound in an air-core flat manner on the upper surface of a stator yoke provided horizontally on the outer cylinder of a vertical shaft to form a single-phase four-pole. The rotor frame, which has magnets and blades attached to the rotor yoke so that there is a gap in the axial direction from these coils, is rotatably supported on the vertical shaft, and a Hall element for position detection is installed. The stator yoke is provided with a predetermined value so that bidirectional current flows through the coil, and the magnetic path changes permeance to generate reluctance torque, and the resulting torque always maintains rotation in one direction. An electric fan characterized by having a pair of notches facing each other at angular positions. 2. The position of the pair of notches is approximately 22. 5' The electric fan according to claim 1 of the utility model registration claim, which is set apart from each other.
