It has an electronic speed controller, doesn't it. One of those where you slow it down and lose horsepower in the process. So they compensate with a bigger motor. Then at high speed, the tooling is small and unable to support all that horsepower. If that is correct (is it?), then the motor will never see full load.
Yes, that is what the website documentation claims ... 220v 9 amps and 1-1/2 HP.
To my knowledge ... based on the website documentation and looking at the pictures ... there is no electronic speed controller. It is a single phase motor. That pretty much eliminates a VFD. There also does not appear to be any controls that might be associated with any other type of speed control on the front panel.
To be clear, I did say "And as others have pointed out, it might actually start and run well enough to meet your needs until you can rewire the garage." and not "It will not run, you will burn your house down."
But we can possibly agree that running the mill in a garage that only has a single 20 amp circuit for the entire garage will be sub-optimal? And even that use case assumes that the motor can be rewired for 110v.
I have a 2 fold Q those who perhaps have the new PM 25MV ( Variable speed new head belt design) and alos those who have a PM 932M. Mill
Yes I know comparing Clementines to Oranges is like comparing BHP to china HP to Taiw HP to New USA to Good ole USA HP . NOT THE SAME IN ANY WAY
Soooo. taken in consideration I would like to ask about HP regarding low end toque and machine capabilities not rpm feed and speed. Keeping that in mind .
Note: On my New PM25 MV I have only drilled but a few holes perhaps tapped ect.... and took off .030-040 from parts still not sue of machines capabilities and if in fact it can handle the new 1" index able mill cutters. I recently purchased. Using RNMG SNMG TNMG style inserts
Those who own owned PM 25MV ( Variable speed new head belt design) what type of depth and metal removal increments are we talking about that my current machine is capable of? lets say mild steel and 6062 Alum?
And same question would apply for the 932M Mill with the China made 1.5 HP motor?
Id really like to hear some feedback to help me make big decision if im gona stay where im at else sacrifice BIG time to upgrade .Already way over budget and still not done with machine Purchasing. Buying a New 10x22 and tooling next month .
I have used a 2" face mill with 3 inserts on my PM932PDF and taken .040" depth of cut in steel. It does not lack power for that kind of cut but the machine is not quite rigid enough for those heavy cuts in steel. Taking cuts of .020" with the same cutter works fine.

That PM 25MV is a light duty mill. If it's adequate for the work you do then there's no reason to upgrade. Like I said before, I don't think too many people complain about their mill being too large.

quick snippet from another post ED so pleze excuse double post if ya read about my band saw refirb proj
need to finish drilling / tapping mounting screws and add angles to base with base archway and be done and over with the mods put this dang thing back together already. Btw I tried out the new mill and its slows me down up and down up and down (limited quill travel ) now I dunno im really thinkin considering getting the next size mill . Was just able to pull off a 5/16 -18 taping operation. But had to finagle a bit to do it. Doesnt seem to have adequate toque even low speed with the magic Juice too ..
