Electromagnet And Method Of Making The Electromagnet

The invention relates to an electromagnet and method for producing the electromagnet. The electromagnet (1) is intended to maintain pretensioning force of fastening by a force acting on a yoke (7) over intended operating time under changing operating temperatures. The yoke (7) encloses an armature (5) that is provided with a flange (15), which conducts magnetic flux from a housing (3) to the armature (5), the housing (3) being connected on the one hand to a flange (15) of the yoke (7) and on the other hand to a core flange (14) in a material-bonding manner by welding. The electromagnet can beused for actuation of valves, couplings or other electromechanical adjusting elements. 本发明涉及电磁体和用于制造该电磁体的方法，目的为：电磁体(1)要在已知的交替的运行温度的同时经过所规定的运行时间通过作用到轭(7)上的作用力获得固定的预紧力。解决方案为：包围着锚固(5)的轭(7)装配有法兰(15)，法兰将磁通流由壳体(3)导向锚固(5)，其中，壳体(3)面与轭(7)的轭法兰(15)、另面与铁芯法兰(14)通过焊接以材料配合的方式相连接。本发明可以应用于阀门、离合器或其他电机式调节机构的操纵。
