Abstract

Laminated magnetic circuit with air gap, comprising and E-shaped part and an I-shaped part (4), and wherein the lenght of the end bars (2) of the E part determines the depth of the air gap opposite the central bar (3) of this E part, characterized in that the side of the I part (4) which rests on the end bars (2) of the E part forms an obtuse angle (alpha) wiht the sides at the end of the part I part (4), and in that the two end bars (2) of the E part each have a prolongation (5) and these are arranged at a distance from one another corresponding to the lenght of the I part (4), so as to fit the shape of the said obtuse angle (alpha) in engaging about the I part (4).
