The smallest spindle that I've found with er16 is 1500W and 220V. I saw that there are vfd's that will input 120V and output 220V but the claim is that performance is significantly decreased, but I haven't seen how much. Does anyone know how the performance is effected? I imagine its reduced torque, but not sure how this looks through the rpm range. I'm pretty happy with 200W cuts on my g0704, and this machine I would be happy with the same, but if I maxed out at 750W that would be enough for me.
So if all you need is 750W at 120V with ER16 collets, then why not just buy an 800W 120V ER16 spindle. Do a search and several choices should be available. Most inverters appear to be 240V, but a few of them are 120V, especially in the 800W range.
