Hello all, another basic question here from myself!

I've managed to 'acquire' a spindle. very similar to this for nothing:

Now i know these are very underpowered and probably pretty useless for most work, but i currently don't have a spindle at all and my machine is just sitting there making nothing at the moment and i really want to start making chips! even if they are only small ones lol.

i'm only going to be cutting wood so i don't mind using a small spindle just for now until i can upgrade.

my question is though what kind of speed controller do i need? or do i need an inverter/vfd? if it is the latter am i just better off buying a new spindle/vfd together like this one?

apologies for sounding dumb, but i'm rubbish with electronics lol.

i have the leadshine mx3660 breakout/driver board so if possible it would be nice to be able to switch the spindle on and control the speed through that. im using linuxcnc.

thanks in advance
