Most probably if it is a synchronous AC motor but asynchronous induction motor as servo motor may be a little bit hard. I think method I tried a few weeks ago with induction motor for other purposes will work but there is a small detail that might cause problem at higher rotational speed. You apply 24VAC and it run as supposed it is most probably an asynchronous induction motor and you might have problem to use them as a servo motor. > http://imgbox.com/rDGX1ayn > http://imgbox.com/cNEavmIg The links are infected with nice looking woman and tricks howto get rid of some stomach fat which might be useful then hunting for womans like I did last night but no electrical data for motor.
