Those Mitsu drives are good for both 3 phase and single phase ... look
closely at the label..So you could run them on single phase 240
volts without problems..

It is often "uncomfortable" to pay too much ( or what you may preceive as too
much ) but it is usually far worse to not pay enough.
A real DC servo, and a 4 brush more specifically will turn smoothly with as
little as the power supplied by a single "D" cell battery with no visual or
audio sign

Were you planning on keeping the original servo amplifiers?
Then, all you need is a compatible motor assembly. You can get
the SEM motors on eBay for a couple hundred $.

and driver combo like I did you can get some decent motor setups from
Machmotion.com. They are made by Teco and they sell mitsubishi and another
brand I think. I used the Teco models on all three axes and they are

Finally have the old Acra mill home where I can have a look at the system and
see what it has and what it needs.
The Z axis has a Baldor (Anilam labled) FMDB-00 and the Y axis has a
Miltronics (also Anilam labled) MT30M4-5. There's no X axis motor but I assume
it would have been the same as
