Triac ATC mechanism wanted

Triac ATC mechanism wanted.
Has anyone got a complete triac ATC mechanism, that has been removed from a machine and no longer needed? I dont need any control gear just the mechanics, I am in the midlands region.

Re: triac spindle motor (servo)

Ok found the manual it all looks straight forward,hope it works,as i havnt put power to it yet.
if not Ive got a eurotherm 508 that should do the job.

The machine has the servo type spindle motor,
I would like to control it passively with just a switch and a pot for now,how do I do that?

those servo's

Hi, I think that machine was mine I have sold it now,not to paul though. The little 24 volt scooter motors work very well,there 6 amps and will take loads of abuse,plus you can buy them off ebay for about £10 brand new. As far as "cogging" goes there not to bad, yes proper servos have skewed rotors ...

yes, I think this Video gives you all the reason you need to use gecko g340's and servo motors,I wouldnt entertain using steppers on a machine build/conversion now-there nothing but trouble. yes servos can be more expensive,but there are numerous ways to reduce this (attach cheap HEDS encoders to an...
