Replaceable alternator rotor windings

Click For Summary
SUMMARY

This discussion focuses on the feasibility of using interchangeable rotor windings for a 3-phase alternator with varying shaft lengths. The participant suggests threading the existing shaft and using extensions with sleeves, indicating that custom machining and winding would be necessary. Additionally, the discussion highlights potential challenges in mounting the alternator and maintaining belt tension, particularly with dual-sided belts. Overall, the conversation emphasizes the need for tailored solutions in alternator design.

Has anyone ever heard of a rotor winding that can be interchanged with different shaft lengths? I'm trying to find a way to create a 3-phase alternator with a through shaft to attach pulleys on each end.

I sure haven't. Could you thread the existing shaft and connect extensions with sleeves?
 
probably have to custom machine it and then have it wound. any decent machine shop could produce it. how would you mount the alternator? this might be another problem. most alternators are the tension on belts attached to them dual sided belts would make keeping the tension problematic.
