Re: 8.1kw 380v brushed DC spindle driver replacement?
Is there any opportunity of getting the original repaired?
Large DC motor controllers are very expensive. You also have to consider the condition of the motor, brushes and comm wear etc.
Also ensure it is not just the field power registering a field loss of its power supply,
Do you intend to run on 380 3ph supply?
