Re: Brushless Servo

Yes Jon... absolutely right with closer inspection it's dca is 2.1 amps so I
guess not a lot of use for too much.

On this list i think people have mentioned that the older large central
computer processors are a source of quality motors suitable for axis drives.
The suggestion was that the tape drives..the sort that drive those big tape
reels on the vertical face of the processor...so beloved in 'Hollywoods
James Bond mad prof control rooms ilk' are quality servos or steppers. Can
anyone expand on that are there any names that have those ie. IBM
models......etc. so I can take a look about here and are they steppers or
servos?
thanks all
