These are the standard motors used with the servo drive. There is a 9.985:1 gearbox on the front of the motor. On the other end is a 500 tick encoder. The green circuit on top is only there as a RJ connector for the encoder. 
They are rated to 19 volts but can be run on 12 volts. 
You can find similar motors on the internet for less. You do need the encoder and the gearhead. 
New motors likese can be purchased new from www.clickautomation.com. Be aware that those motors are approx. $250.00 each. 
The price for these is $150.00 each.

You just need to add the cable drive hardware, friction knob or a timing belt and pulley to each axis. ( these are available at www.mcmaster.com). A cover in wood, platic or metal is recommended.  The large timing pulley can be a smooth disc, in wood, HDPE or Aluminum, available from us. Click here for more information.
