Hello,
This is my first time posting, so let me know if this isn't the right place for this.
I recently purchased a Kent knee mill, built around 2005.
This is primarily a hobby machine, in my garage.
It has an Anilam 3000m control which seems to be working as intended, so far as I can tell so far.
My question though, is about powering the spindle motor.
I have been doing quite a bit of reading on the topic of phase converters and VFD's, but I am very far from an expert.
It's a 3hp motor which, in it's current state, is powered by a 3hp 3 phase rated VFD, I believe.
It's a Parker Hannifin drive, discontinued, but I was able to find some documentation on it, attached.
I have 220 volt single phase to the garage.
From what I understand, the VFD needs to be derated to be used with single phase, so I would need a 7.5 or so VFD to replace the existing?
Can a VFD be run off of a phase converter? What are the pros/cons in this situation?
Here's the other thing- if you check out the manual, my drive actually has a "high capacitance" capacitor bank, which explicitly states for use with single phase. But it doesn't technically say that it can be used with single phase without being derated - less than the 3 hp 3 phase it's labeled as.
Could I possibly upgrade the wires from 12 gage to 8, and just run as is? Could it be harmful to try?
If I were to get a higher power rated vfd, could I use the existing control panel? It's pretty well integrated, and looks nice, so I would prefer to keep it.
Can a VFD run off of a phase converter? It's odd how didfficult it seems to be to find information on this exact situation - already have a vfd, but need single phase.
Thank you so much in advance for any help to get me going in the right direction.
