Abstract
A method for testing an SMC stator core for an electric machine includes providing the SMC stator core to be tested and providing a plurality of windings in the form of printed circuits, The SMC stator core includes teeth and each printed circuit has cutouts which are adapted to the shape and arrangement of the teeth. The method also includes placing the printed circuits, which are stacked on top of one another, onto the teeth, covering the arrangement of the SMC stator core and the printed circuits with an iron return ring, which contacts the teeth, and operating the printed circuits as transformer windings while acquiring properties of the SMC stator core, which acts as a transformer core here. A device for testing the SMC stator core using the method is also disclosed.
