Re: Servo Motors....?

Hi Jon
Thank you for the reply. Made a big mistake on the encoders, didn't
I. I guess I should be reading these threads a bit more closely and
then I may actually learn something.
If they are no good then I will use them for something else like a
clothes line retractor or something equally rewarding but I really
appreciate the help as it saves a lot of stuffing about in the dark.
Just one query tho', How would I go about finding the peak current.
Thanx for your help.
Richard.
