Abstract

An inductance coil of the type comprising at least one coil winding (10) of wire alternately disposed with respect to channels (11) for the passage of the cooling air, said at least one winding (10) being at least externally encompassed by an insulating cylinder (13), at least outwardly of said at least one coil winding (10) and of said insulating cylinder (13) a ferromagnetic core (15) being concentrically mounted with respect to said at least one winding (10), said core (15) extending along about at height of said at least one winding (10). Conducting short-circuited turns (16, 17) at the ends of the winding (10) and carrying the same current as the winding (10) itself, are furthermore provided to eliminate dispersed magnetic flow.
