myford super7 3 phase conversion (again) nickphill 03-02-2008

I'd like to convert my Super 7 to 3 phase. I think I will go the
inverter route. Can anyone point me at a solution that won't require a
lot of electrical troubleshooting. I haven't got 3 phase to the house.
Thanks
Nick

Depends how much cash you have and how much trouble you want. For a "plug
and play" solution look at the Newton Tesla setup:

Not cheap but very easy to fit and works like a dream - just swap the motor
pulley to the new motor, bolt the motor into place and plug into the
controller

Alternatively, a three phase motor and something like the Eurotherm drive:

Either way, well worth doing

post in the yahoo myford group that you would like to do this

and I'm sure there will be one or two members there ...who have gone
the other way

and taken all the three phase equipment off their three phase
machine ...
and gone to 240 volt

and will only be too willing to sell you the old gear .

all the best.markj

and if you can find them

they also make single phase to single phase inverters as speed
controllers .

BTW .......i still have a myford three phase motor ........transformer
for the lighting and control circuit ...and the myford three phase
suds pump ....make me an offer ......

all you need to find after that is ......a myford 3 phase motor
starter relay and possibly reverse switch

all the best.....markj
