る。Additionally, a method has been proposed in which sheet coils are manufactured using photoetching technology, but in order to secure the required number of turns, the pattern must be made narrower, which limits the current capacity. Ta. In this case, it is possible to increase the current capacity by stacking multiple sheet coils, but doing so will make the coil thicker.
The advantage of sheet coils, which are characterized by their thinness, cannot be demonstrated.

４０の終端をハンダ、圧着等により電気的に接続する。In order to achieve the above object, the present invention has been developed by winding a thin steel foil around a long core material having a predetermined cross-sectional shape for the length of the coil winding, and then cutting it into 111-cuts according to the current capacity. [Embodiment] In the present invention, as shown in FIG. 2, a coil having a thickness of 18 μm-10
A pipe-shaped pin 4 is attached to the starting end of a steel foil 40 having a predetermined width of 0 μm and coated with an insulating material that also serves as an adhesive such as polyurethane or epoxo thread 414 on one or both sides.
The starting end of the steel foil 40 is attached (by contact or crimping) to a core material 44 formed into a desired cross-sectional shape using an insulating material such as polyurethane or epoxy resin, and then the steel foil 40 While applying adhesive to 1IliiD, the wires are wound around the core material 44 according to the required number of windings. When winding is completed, a pin 46 is fixed to the surface of the coil body at a position facing the pin 42 by adhesive or the like, and the terminal end of the steel foil 40 is electrically connected to this pin 46 by solder, crimping, or the like.

The pins 42 and 46 may be connected to the coil by soldering using a lead wire or the like. In the case of connection using a wire or the like, it may be provided at any position; however, in the case of mounting on a printed circuit board or the like, it is necessary to provide it in a predetermined position.

The coil 60 obtained in this manner is installed at a predetermined position on a printed circuit board, and connected to the circuit board pattern by crimping or the like via another pin to the pins 42 and 46, or is provided so as to protrude above the circuit board. Then, the stator is completed by fixing the required number of coils 60 to the board with adhesive or molding F etc. The current capacity is determined by the width (thickness) of the cut coil and the steel foil 40. Since it is determined by the thickness of the coil itself, both can be selected as appropriate depending on the space etc. when installing the coil.
