02.01.04 Test bench for stator active steel

Test bench for stator active steel 02.01.04 is intended to determine the condition of the stators in the repaired electric motors with the capacity up to 100 kW after winding removal. TestbBench selects cores with high losses before laying new winding and reduces unnecessary waste of the winding material.
