Evaluating High No-Load Amps of Three-Phase Motors
This presentation focuses on the steps to take before rewinding to avoid the undesirable situation of high no-load motor amps after the rewind.
The presentation covers the following steps that should be performed on every AC stator rewind:
- Inspect the stator bore and rotor outside diameter for evidence of machining or damage
- Record the original winding data exactly as found
- Verify the winding data
- Test the stator core before and after rewinding removal
This presentation is most useful for service center mechanics and winders with any level of experience, and service center supervisors and managers.
