3phase 3speed motors
(OP)
thread237-313373: 3phase 3speed AC motor winding connections I have a 3speed 3phase motor 480 volt with no schematic to go by. My question is, is there a way to read the resistances of the 9 motor leads and know which 9 power leads these go to. It's very confusing. No name plates or diagrams to go by. The power comes from 3 magnetic starters on anotherfloor in in buiding. Any help or suggestion would be greatly appreciated.

If yes, then you have a 2-speed 1-winding motor and another seperate 3-phase single speed winding. The single winding will be easy to determine but you may need a motor shop to sort out the 2-speed 1-winding part.
If no, then you should have 3 seperate 3-phase windings. This should be easy to determine by continuity.
