Abstract

The invention is to provide an aligned multilayer wound coil that is compact in size, and is excellent in productivity, an apparatus for manufacturing the same, an electrical equipment, and non-inductive resistance to which the aligned multilayer wound coil is applied. The aligned multilayer-wound coil comprises two, or more winding layers, the winding layers being provided with insulated electric wires, respectively, wound in one direction in alignment with each other, wherein a lead wire is guided out from respective ends of the coil, on a layer-by-layer basis, and wherein the lead wire guided out from one end of the coil on a layer-by-layer basis is connected to one terminal while the lead wire guided out from the other end of the coil on a layer-by-layer basis is connected to the other terminal, and winding layer coils on a layer-by-layer basis are connected in parallel with each other on a circuit.

Claims

1. An aligned multilayer-wound coil comprising two, or more winding layers, the winding layers being provided with insulated electric wires, respectively, wound in one direction in alignment with each other, wherein a lead wire is guided out from respective ends of said coil, on a layer-by-layer basis.

2. The aligned multilayer-wound coil according to claim 1, wherein the lead wire guided out from one end of said coil on a layer-by-layer basis is connected to one terminal while the lead wire guided out from the other end of said coil on a layer-by-layer basis is connected to the other terminal, and winding layer coils on a layer-by-layer basis are connected in parallel with each other on a circuit.

3. An aligned multilayer-wound coil comprising two, or more winding layers, the winding layers being provided with insulated electric wires, respectively, wound in one direction in alignment with each other, wherein aligned wound coils in respective layers are connected in series with each other on a circuit.

4. The aligned multilayer-wound coil according to claim 3, wherein the number of windings in a specific layer is adjusted in order to adjust inductance of the aligned multilayer-wound coil.
