Checking the archives I see several entries that makes sense - however, does not cleanly map to my circumstance. I am looking to parallel to a old (~1965) GE 480V, 3 phase, 6 pole, 1200 rpm generator. The stator shows 108 slots and a pole covers 14 slots. From what is written, the pitch is 14/(108/6)= 14/18 = .778 pitch or 7/9. I expected to come up with a standard value of either of 2/3, 4/5, 5/6
Nothing in the manual regarding pitch
Could it truly be 7/9?
