Neil,
 
I dont envisage any problems fitting a three phase motor, at the moment , the inverter is going into its own box as I want to fit a potentiometer to control the speeds plus an EM Stop. The unit is fan cooled so the box will also have filter inlet and outlet ports to stop muck getting in, a bit OTT you may think but I work with these units in my job and they will run for ever if you look after them.
 
The reason for change is the flexibility I will get, thread cutting wont be so frightning because of the fast lowest speed I currently have, DC Braking etc.
As it comes together I will keep you in the loop.

Gentlemen,
 
This is my first posting on this Forum and I'm wondering if anybody knows a supplier of good make 3/4hp three phase motors for my lathe.
I have recently acquired a Seimens 420 inverter and now I'm looking for a four pole motor to go with it to convert my lathe.
 
Thanks,
 
Martin Perman
