A coil winding device for a flat motor as disclosed in Japanese Patent No. 159952 is used.

FIG. 12 shows a coil element formed by the coil winding device for a flat motor disclosed in this publication. This coil element has coil wires e stacked several times on the same plane. It is formed into a flat shape by being wound into a shape.

FIGS. 13 and 14 show a coil winding device for a flat motor disclosed in this publication. This coil winding device for a flat motor draws out a coil wire e wound around a bobbin 1, The coil element E is formed by passing through the trumpet 2 and repeatedly winding it in a stack in the same plane to form, for example, 25 coil elements E.

That is, this flat motor coil winding device has a trumpet guide 4 and a coil retainer guide 5 on a base 3, and the trumpet 2 and the coil are arranged along the guides 4 and 5. Although the presser foot 6 slides, it is necessary to move the presser foot 6 in a pair, so the link 7
Connected by.

A mold assembly 8 is rotatably supported by a bearing 9 between the guides 4 and 5. In this mold assembly 8, 25 mold pieces 10 are connected to each other and a shaft 11 is inserted through the center of the mold assembly 8. A handle 12 is attached to one end of the shaft 11 for rotation.

As shown in FIG. 15, each mold piece 10 has
A through hole 14 through which the shaft 11 is inserted is formed in the center of the disc 13. The through hole 14 has a substantially trapezoidal shape as a whole like the longitudinal cross-sectional shape of the shaft 11,
A protrusion 15 is projected from the peripheral wall, and a spacer 16 is fixed to the end surface of the protrusion 15 with a screw.

The spacer 16 is for forming a gap between the mold pieces 10 which is slightly wider than the diameter of the coil wire e. Therefore, the outer end surface 16 of the spacer 16 is
a is the case where the shaft 11 is inserted into the mold piece 10,
Together with the outer peripheral surface of the shaft 11, it serves to form a part of the trapezoid that is the shape of the coil element E.

In the coil winding device for a flat motor constructed as described above, first, all 25 mold pieces 10 are fitted and inserted into the shaft 11 and fixed by using an appropriate tightening tool. After that, when the winding around each mold piece 10 is completed, the mold assembly 8 is taken out together with the shaft 11 and heated. By this heating, the epoxy resin on the outer peripheral surface of the coil wire e is melted, and when the epoxy resin cools, the windings are temporarily bonded to each other.
