ABSTRACT:
A laminated core testing device for testing laminated cores in a generator is provided. The laminated core testing device includes an exciting winding situated parallel to a rotation axis of the generator and connected to a secondary alternating current generator, and further includes an infrared image acquisition device for acquiring infrared recordings. The secondary alternating current generator has a controllable frequency converter, and the secondary alternating current generator, at a frequency ranging from 400 Hz to 600 Hz, provides, in a single-phase manner, an output of 200 kW with a controllable output voltage ranging from 0 V to 3.0 kV.
