I plan to add either a set of the mini Pittman or Faulhaber servo gearhead motors with encoders to drive a small 3 axis closed loop CNC setup. So the servo drivers will be connected to the encoder. I need some help or advice if these types of motors are a good choice for CNC work or not.
The small servo motors which I'd like to use have gearheads which gives them needed torque to drive a CNC axis. The problem I noted is these gearheads do have a small amount of backlash <1 degree according to the product specifications.
Since the servo motors also have very accurate encoders, will these encoders correct for this small amount of backlash or will it be accumulative which means these small motor gearhead setups are not good for using with CNC equipment?
