thinking about how to power this mill
so, after wanting a milling machine for a few years, I broke down and bought
one - this one http://cgi.ebay.com/ws/eBayISAPI.dll...tem=7556615290 to be specific. I've mailed $$ to the manufacturer in Sweeden who will send me the manual (cheap, 55 euros), so now while I'm waiting for delivery, I'm turning my attention to the next problem - how to power it. You will notice that it says it's 440V - I don't know if the motors, etc are dual voltage or not, but my garage doesn't have 440 in it. Of course I can use a transformer and a bunch of VFDs or a rotary phase converter, or .... but I wonder what the group experience might be. I can also rewind the motor for 220 and use an off the shelf VFD, or I can modify a 440V VFD so it accepts a DC input and then make a DC power supply (e.g. full wave doubler) to supply it from the 220, or ....... so, what do you think? -- Bill www.wbnoble.com |
