Lathe Reverse

[blackburn mark]

There are 3 variations of common induction single phase motors.

Most of that is rocket science to me... I get the general, gist I think.

I am running on the deduction that IF cap on pin2 = Forward and the cap on Pin4 = Reverse then the bus bars cannot be jumpered twixt Pin2 and Pin4 for reverse because that would eliminate any need to swap the cap from Pin2 to Pin4 so I have been unknowingly / randomly jumpering pins via the tumbler switch until I hit (1<----->2) + (3 <------> 4) where it will run in either direction depending only on the capacitor placement.

Having said that, I was 99% sure I had cracked the problem earlier and I was wrong so I'm going with 98% this time

This and other similar images had me convinced it was all in the bus bars.


I wont know for sure until Sat.
