Hi All,
I've just bought a Super 7 on eBay which is currently single phase. I have been used to an ML7 with a 3ph dual voltage motor running off a VFD and rather than put that back to single phase I want to buy a new motor and convert the new one to 3ph.
I think this means that I need a 4 pole motor running at 1425rpm which I haven't seen on eBay over the past fortnight. What I have seen (and has just been re-listed) is a 1hp dual voltage 2 pole motor running at 2860 rpm.
So my question to 'the panel' is - Does it matter - 2 pole or 4 pole
- 1450 or 2860 - if I intend to run it via a VFD?
My thoughts are that I could program the VFD to provide a maximum of
1425 rpm (or there-abouts) but I have no idea whether that would reduce or increase the potential torque, or cause any other problem that is beyond my wit to imagine!Your collective wisdom would be most welcome.
