Chinese 300W DC spindle - is the spindle shaft grounded?

[Lee Roberts]

The way I see it, the only way the shaft wont be earthed is if they have ceramic bearings

Yea was going to say ceramic...

Would you like some photos?

If you dont mind that would be great, i'm guessing Hank has offered to buy this off you now but photo's of it here would still be nice, as i bet there isn't any online and would serve us well for other people to come (archive kind of thing).

I would love to know where the break is... there must be one between the shaft bearing and body and I just cant see it being ceramic bearings?

Agreed, photo's me think's!

Spinle can be easy grounded also during operation. Add the axial brush in the top...
