Cant see any downsides to having a VFD on a tablesaw, I have a Huanyang 2.2kw vfd/inverter
on my Startrite 3hp tilt arbor, and have never bogged it down at full capacity ripping hardwoods.
This "no downsides" in my case, means I use it for my own personal hobby use in my garage.
I don't have a business or let anyone else use it, nor share a building with any sort of business operating.
I run mine from a standard household 13a plug.
This saw has a dual voltage motor, so its 240v volts out in my case (low voltage Delta, triangle symbol)
What saw is it? .... or to be more precise, what does it say on the motor nameplate? (the motor could have been swapped out)
Do you see the 240v or a triangle symbol anywhere on the saws motor?
This will be stamped on the motor nameplate along with the high voltage "star, high voltage
(Y symbol)" option.
If you don't see this delta 240v option you have two choices...
1. Dig out the windings and configure the motor to make it a dual voltage motor, changing it from a previously "fixed star wound motor"...
It has been shown here before, what needs to be done, Haven't done this yet personally, but wouldn't worry too much about it now. (I am a frugal fellow)
2. Buy a VFD/Inverter that costs about 150 quid that is Star high voltage out,
Instead of a cheaper one like the Huanyang that is 100 quid... or even less money for a lesser familiar one, what might take a wee bit of figuring out how to program.
I'm guessing that these cheaper ones will only run dual voltage motors... running it on low voltage.
You will have to check the voltage output on whatever specific VFD you are looking at
Make sure you know this before hitting the buy it now, the devil is in the details.
This is of no concern if you don't mind opening the motor and doing a bit of work, as mentioned above...
But personally (I have no electrical knowledge whatsoever) with my first VFD experience, I would rather get a VFD that is more straight forward to use out of the box.
Still a good idea to have a look inside a motor for sawdust and give it a clean if needed.
Good luck
