Electrical sheet metal packs for electric motors or generators

Abstract

In a method for manufacturing metal bodies, e.g., stators for electric motors, a stack of sheet metal parts (14), which have thermally-curable adhesive layers provided therebetween, is guided over a mounting mandrel (11) of a tool, and/or is held by an external fixture (25). The stack is then heated to cure the adhesive layers while applying pressure thereto, thereby forming the metal body. In the course of the method, at least one of the applied pressure, the temperature of the stack, and/or the height of the stack is measured. A prescribed height of the stack is adjusted by performing a temperature-pressure control. The present system and method enables efficient and precise production of stators, is self-learning and enables the measurement, regulation and recording of all manufacturing parameters in the course of the manufacture of each individual stator. In particular, all manufacturing parameters can retrospectively be associated with an individual stator.
