Abstract (en)

[origin: WO8907325A1] A process is useful for making an iron body with a winding for generating electromagnetic fields. The iron body comprises an essentially parallelepipedal iron core (6) and at least one U-shaped iron yoke (7) for accommodating a section of the winding, the iron core being inserted between the branches of said yoke. The iron core (6) is inserted in the winding in which the wires are initially undeformed, and the U-shaped iron yoke (7) is slid on, the core (6) and yoke (7) being moved relative to each other until the cross-sectional area of the groove bounded by the core (6) and the yoke (7) or of the winding space is smaller than that of the initially undeformed section of the winding accommodated in the winding space of the iron body formed by the core (6) and the yoke (7). The core (6) and the yoke (7) are pushed together with a force such that the originally circular cross-sections of the wires which constitute the winding are permanently deformed over the length of the groove or winding space in which they are accommodated.
