Re: Chinese 2.2kw spindle burned out?
I run my air cooled spindle at 12,000 rpm all day nothing happens, the min speed is set at 9,000 rpm. Grounding since its a 3 phase has zero to do with it as the ground is for protection or equipment ground when something goes wrong. Shielding or lack of, why would that make the motor burn out?? VFD Parameters set wrong, very well could be, mactec54 can handle that and I would sure check before I installed another spindle. I will agree, the wiring is nothing I would be proud of.
