Abstract
The present invention relates to an external stator for a plane motor, which is composed of a wire winding body, a magnetic core and a molding body, wherein the molding body is composed of a first molding part, a second molding part and a third molding part; the first molding part is combined on the outer circumference surface of the wire winding body; the second molding part and the third molding part which are continuously formed are combined at both side surfaces of a connecting part of the magnetic core; the third molding part and the second molding part which are continuously formed are combined on the partial outer circumference surface of the magnetic core. The external stator for a plane motor of the present invention is only formed on the partial outer circumference surfaces of the wire winding body and the magnetic core through molding bodies combined with the magnetic core and the wire winding body, and the tail end of the molding body formed on the outer circumference surface of the magnetic core is made to present a zigzag or a triangle. Thus, while the contact area of the molding bodies and the magnetic core is enlarged, the pressure of the molding bodies to the magnetic core can be reduced. Accordingly, the deformation of the magnetic core and the wire winding body due to the molding pressure and shrinkage force can be reduced to the maximum, so a gap between the external stator and an internal stator can be maintained constant.
