Lathe Reverse

[Sterob]

I helped a mate repair his single phase lathe a couple of years ago after the starting switch fell apart and someone lost some of the parts!
I had trouble reversing the motor ( think it had a cap on it....)
I found that the 'run winding' was centre tapped and , which was neutral and the Active was swapped to either end of the winding to change direction.
This meant that single phase lathe and the 3 phase lathes could use the same sort of drum switch, ie FOR- Off - REV.
I did a drawing but its at work.

Yours may be the same.


I have Rosenburg ( Electric Motor Bible) and there is only a very small mention of this sort of motor in it!
