Method for producing a stator magnetic circuit of rotating electrical machines or a magnetic circuit of transformers, and a magnetic circuit thus obtained

摘要

The invention is in the field of design technology of magnetic circuits of electrical machines. The method provides, in particular, the formation of cores of stamped-out magnetic metal sheets which are joined to one another and are connected to one another on the sides which rest against one another. The cores can be connected by welding on the sides resting against one another or by means of a plug system between connecting attachments and grooves (12, 13) in the metal sheets of a core with the metal sheets of the adjacent core.
