Hello Richard Jones, I found this topic on RMweb whilst searching for solutions to repair or replace my Emco Unimat SL lathe motor. I found the items you used to replace your motor with a 24 volt scooter motor and ordered them (they are a little bit more expensive now but still reasonable) however there are no instructions included on how to wire them up. The switch mode power supply is straight forward enough (mains in one end a 24 volts +- out the other) but the pulse width speed controller was supplied with the three way switch separate, and no wiring instructions. Of the other connections, I assume the +- on one side is from the switch mode power supply and the M1 M2 are to the motor. I just can't figure out the way the four wires (two black two red) from the DPTT switch connect to the four connectors which are labelled out, out, in in respectively. I've tried contacting the seller on Ebay but his English is very poor and I don't speak mandarin so we are at an impasse. would appreciate your help.
