したことを特徴とする円筒型フアンモータ。 Field magnetic poles 4 of different polarities are arranged opposite to each other in a casing 5, and a rotating armature 2 is held on a rotating shaft 12 through a predetermined gap between the field magnetic poles 4.
In the cylindrical fan motor in which a fan is directly attached to the cylindrical fan motor 2, the shape of the field magnetic pole 4 is formed such that the circumferential length of the field magnetic pole 4 increases successively at each position in the axial direction, with the circumferential length of one end thereof as a reference. A cylindrical fan motor characterized in that the armature 2 generates a force in the rotation axis direction to cancel the thrust force generated by the rotation of the fan.
