Ｂが設けられている。Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In the figure, 1 is a flat armature in which a polygonal single coil is resin-molded into a disk shape.
A large number of fins 2 are provided on the outer periphery. A hang magnet 3 faces the armature 1 with an axial gap therebetween, and is fixed to the inner surface of the load side bracket 4. 4A and 4B are air holes provided near the outer periphery of the ring magnet 3 located on the axial end face of the load side bracket 4 and near the outer periphery of the concave bearing holding portion 4C, and the air hole 4A is formed by cutting and raising. . At that time, the cut-and-raised piece 4aF is the wind hole 4
It is located above A, and its cut-and-raised piece 4a is inclined so that its tip is located downward. 5 and 6 are single negative side brackets surrounding the armature 1 together with the load side bracket 4; 7 is a shaft rotatably supported by bearings 8 and 9, to which the armature 1 is attached; 10 is a load side bracket; The fan is attached to the tip of the shaft 7 that passes through the bracket 4, and is provided in a cup shape so as to surround the load side bracket 4.
A plurality of fin blades 10A are provided on the outer periphery, and a bearing holding portion 4 of the load side bracket 4 is provided.
A fan ring 10 is installed on the inner wall facing the outer periphery of C.
B is provided.
