摘要 PCT No. PCT/EP89/00064 Sec. 371 Date Sep. 14, 1989 Sec. 102(e) Date Sep. 14, 1989 PCT Filed Jan. 23, 1989 PCT Pub. No. WO89/07325 PCT Pub. Date Aug. 10, 1989.A method for the fabrication of an iron member with a winding for generation of electromagnetic fields. The iron member has essentially a square-shaped iron core (6) and at least one U-shaped iron yoke (7) receiving a segment of the winding; the iron core is inserted between the legs of said U-shaped iron yoke. The iron core (6) is introduced into the winding having to begin with undeformed wires and subsequently the U-shaped iron yoke (7) is slid on. Herein core (6) and yoke (7) are moved so far against each other, that the cross-sectional area of the groove bounded by the core (6) and the yoke (7) or of the winding space becomes smaller than the cross-sectional area of the segment of the winding which it to begin with not deformed and received by the winding space of the iron member formed by the core (6) and the yoke (7). Core (6) and yoke (7) are pressed against each other by a force so large, that the originally circular cross-sections of the wires forming the winding are permanently deformed across the length of the groove or the winding space receiving them.
