Abstract (en)
[origin: JPH0273610A] PURPOSE: To improve the productivity of a twin coil having excellent characteristics, by providing windings of opposite polarities by arranging individual coils on a common coil bobbin with a substantial gap between each coil, so that undesirable coupling can become the minimum. CONSTITUTION: A coil bobbin 1 is provided with four flanges 2 which define two winding divisions 3 and 4. The relative positions of the two cores 9 and 10 are settled and windings are arranged at the winding divisions 3 and 4 of the bobbin 1. A vertical winding W3A is connected to a compensating winding 8 marked with W3B, composed of several turns, and reversely extended over the full winding width in the division 3 which houses a secondary drive winding 6 marked with W1 and a primary drive winding 7 marked with W2. Since a twin coil is constituted in such a way, the productivity of the twin coil can be improved.
