24 forum posts 7 photos	I have at last got hold of what I hope is a good motor to replace the defunct motor on my ML7 Myford. The lable says it is a Brook/Crompton "Invensys" 3/4HP single phase I have seen a video of it running. It sounded quiet and it looks in good order. It has resilient mountings and I'm told it dated from 1994. I have rewired the lathe with an NVR switch, to use the Dewhurst switch only for switching to reverse when the power is not connected, and now all I have to do is connect the Dewhurst to the motor. The problem I am now faced with is that although the wires coming from the windings seem to match those I have seen in a guide to connecting a Brook crompton I found on line, but the markings on the connections board are very different. They are from left to rightZ2, R, S, U1 & U2 and P (which is unused. So I'm hoping somebody has a similar motor or is familiar with it. The bare wire links between U1 & S and between U2 & R are somthing that puzzle me.

Run winding on U1 and U2 The bare links are for connecting Live to the start winding and the other bare link is connecting the start winding to Neutral. Emgee Edited By Emgee on 25/09/2020 17:44:43
