Abstract (en)

[origin: DE19726055C1] An electromagnet system including a yoke (1) and having a core (2) which is fixed with a fixture end (23) in a round hole (13) of a yoke section, in which the core (2) has a preferably cylindrical shaft (24) and a conical section (25) widening to it's fixture end (23), the conical section piercing the yoke material with a core diameter exceeding the diameter of the round hole (13). On the conical section (25), is formed a thread (26,27), the conical section being inserted with self-forming threading on the threadless wall of the likewise conically widening recess (13) of the yoke (1).
