Emco Mentor Mill conversion

Swarfing, once the correct value cap has been established, apart from the "start" cap you are still only putting "C" across one leg of the delta (or am I missing something?). To give the correct "C" value you may well decide to use a combination of caps to achieve that value, but a single item of the correct value can usually be found. If Ross already has an inverter then obviously that is the best way ahead for him. I only make this point because I would not like to be thought of as misleading anybody. G.

G it was a long time ago when i did mine, you may be right so don't think you are misleading people. Mine would not balance across each phase so had to tweak with various caps to balance. If one phase runs out of balance then it would contribute to a short life of the motor. Bear in mind mine was 69 BP i applied this too. look at the second image up on the link i supplied earlier in this thread and you will see what i mean. That is the way i followed and it works a treat with only slight loss of torque.

Yes, I think its a great way to do it for very little expense and whilst I am aware that it is "quasi" 3 phase, I have never noticed any power losses. Mind you I have never had the real thing, so I wouldn't would I? G.
