This one is 1.5kw (2hp) water cooled, ER16 nose, 24000rpm, 400hz.
I use a Hitachi SJ200 VFD. It was only a little more money than a Chinese one and I decided to go this way.
I use a Homman Designs DigiSpeed to interface the control to Mach3. Works a treat.
It leaked a little water when I got it. Easily fixed. But the water leaked in a way that it went past the bearings. Will it reduce the life of the bearings? I don't know.
Another user here in Aus. got one with one winding shorted to the case. Again easily fixed but that is sometimes what you get from China.
Overall I am very happy with it. I would definitely buy one again.
