SUMMARY
The discussion centers on troubleshooting weak performance in 12 amp 1.8 degree stepping motors. Users report that despite checking bearings, windings, and insulation integrity, motors occasionally exhibit weakness. The primary suspect for this issue is the potential presence of shorted turns in the rotor, which can absorb significant energy without altering resistance readings. This highlights the importance of thorough diagnostics beyond standard checks to identify underlying magnetic issues.
