Emco Mentor Mill conversion

[Ross77]

finally found time to rewire the motor and it was embarrassingly easy, don't know why I was so worried about doing it. Coils measured 50 ohms on their own so in delta config you basically have two coils in series which are also connected in parallel to the 3rd coil, so if I have it correct then that gives 100 ohm and 50 ohm in parallel which is 33.3 ohms. tested each pair of wires and always got 33.3 ohms so hopefully I have got it right.


Also worked out how to set up the vfd, connected a forward/reverse switch and a speed pot. tested it on a another motor and all works fine. so hope fully tomorrow I can rebuild the motor and see if it works.
