Abstract

Improved core for electric coils, especially for automatic tension stabilizers, characterized essentially by consisting of a parallelepiped carrying block, on its main faces, of a rectangular and elongated opening, which have their sides greater and approximately one third of their length two facing projections of similar length, ending one of them, in convex form and the other rectilinear, susceptible of receiving between them the greater section, of the complementary element of the nucleus, constituted by a block in the form of a cross, whose greater side has an incoming concave in correspondence with the convex projection, while its equal arms terminate convexly, in correspondence with concave recesses of its same shape located on the inner sides of the cavity, which will thus receive between the two associated pieces a maximum number of three carrier spools of electromagnetic induction windings, defined between, the longitudinal ends of the cross and the smaller sides of its frame each rectilinear spaces forming air gaps of constant dimensions.
