Servo find

[vulcom1]

Today I was given 2 heads from an xray machine. The part that has the camera in them. From what I have noticed is that there are servo motors inside and all I can see for specs. are 115v CC 22 SRV. They are 35mm in dia. and the case is 85mm long. They have 5mm shafts that are chain and sprocket drives with a bunch of gears. They also look like they have a small motor attached to the mechanism for each one.
If anybody could give me some info on these it would be appreciated. I am trying to learn cnc to go along with my other hobbies and am slowly but surely gathering parts to do something.

At those dimensions they sound like micro Motors. They will be exceedingly small to do anything CNC related, in all probability.
Also if the are 115v, they could be ac synchronous motors, Is there a make on them?
Is the 'Small Motor' and encoder by any chance?

the 'little motor' is probably an encoder of some kind, how many wires do each have, also is there a manufacturers mark on the motors somewhere? Also you may not have the drive electronics in the bit you have, but i would expect these to be dc servo motors, and there to be a motor controller somewhere else running on 115vac

If you let us know how many thick power wires there are running to the motor, and how many thinner wires there are to the encoder (or back of the motor), then maybe i can be of more help.

To be honest motors which are specced to move a camera quickly wont have anywhere near the torque you need for a cnc moving platform, but could still be useful for some other project.

Thanks for the answers as I was not sure what I had or if they would be any good. The motors have 3 wires about 26 guage(red,blue,yellow) and the others I believe are rotary pots with 1k marked on them. They have a heavier guage 3 wire on them. I am going to disassemble everything and keep them along with the chain and sprockets. They also have some rack and pinion parts and brass gears. Being a bit of a packrat with hobbies they might be of some use later.
Thanks, John

The motors probabally do not have brushes then.
If you measure the resistance of the three wires to the motor and they register the same, they could be syncronous stepping motors.
AC servos or BLDC require commutation (more wires).
The pots are for simple servo feedback position, they may be 360° continuous rotation type.
