Optimum BF30 Mill - Is Spindle Motor AC or DC
Hi All,
Well, this is my first real post after many years of lurking and learning.
This is such an awesome site! Hopefully in the future I can actually contribute,
but for now here is my question. If anyone has input, I would greatly
appreciate it.
I purchased a new Optimum BF30 and from day 1 the gearbox noise has
really bothered me. I have a video posted here (Turn Up Your Volume):

The Optimum Rep I spoke to said the noise is at least partially due to an
inferior motor driver design which causes motor cogging and resonance.
I asked if it would be worth trying a different motor driver and he thought
it would but could not recommend a replacement.
Now to my question. The Rep said the BF30 has a DC motor but I am not
sure he is correct. Below is the wiring diagram and motor nameplate.

It looks to me like this is a 3 phase AC motor, NOT a DC motor. What do
you guys think?
The reason I ask is I would like to get a VFD (If it is a 3 phase AC motor)
and see if that will quiet down the gearbox.
Thanks for your help!
