Abstract (en)

[origin: WO0049702A1] The present invention relates to a film coil having an improved coil pattern and a fabrication method thereof in the case of a motor and generator which uses a film coil instead of a conventional motor and generator in which a coil is wound on a steel core. In the preceding film coil of a motor and generator, a film coil is printed and plated on an insulation film, and a copper film attached to an insulation film is etched. In this case, it is difficult to stack many coil layers, and in addition, since a coil density is low, the preceding film coil is not widely used. In the present invention, a copper film attached on an insulation film is etched for thereby forming a lower coil, and an insulation film is printed on the coil except for the connection points, and a copper film formed by an electroless plating and electroplating is etched for thereby forming an upper coil, so that a connection between the insulation films is automatically implemented. In the present invention, a connection of the coils opposite with respect to the insulation film is easily implemented, and it is possible to form a film coil for a motor and generator having a high coil density by forming a film coil with a small space loss at one coil layer.
