Using RC Brushless motors as spindle

[M250cnc]

I did the mount today, not the neatest of things I've made with the rotary table but it works:

(Picture tomorrow)

I was under the impression your mill was under cnc control why the RT ?

I ran the motor in for about 5 mins on 12v, soon got bored of that (I'll leave it running properly tomorrow).

Its a temperature thing if it doesn't get hot just keep increasing the speed in increments.

It merely drew 550w and about 53 amps. I'll have to think of a safer way of testing the power at higher voltages.

I think I'll stick with the batteries for now unless anyone can point me to a 50v PSU that can deliver a LOT of current. Maybe a few of those switching PSUs people have been using for steppers on eBay...

Sounds like mum & dad are gonna have a big leccy bill coming.
