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.

02.01.08 Test bench for stator active steel |
|
| The behch is intended to reveal faults in stators of repaired electric motors with the capacity from 100 to 1000 kW after winding removal. The bench reveals cores with high losses before packing new winding and reduces winding wire extra waste. |
