I'm looking for recommendations on 12-24v dc brushed motors and encoders, preferably with the encoders pre-installed, that have been tested with roboclaw and can be accurately positioned via the encoder. A pre-installed gearbox is a plus as that's one less thing I have to mess with.
I would like to avoid anything that uses a cheap hall effect quadrature encoder like the actobotics/servocity/robotzone motors as I've been having issues with the noise on their encoder circuits and do not want to modify the circuits.
I currently have 2x7A, 2x15A, and 2x30A roboclaws so any motor that is drivable by any those would be fine. I'm mostly trying to do a proof of concept so no real load requirements at this point; the only major requirement is that I need to be able to position the motor with some degree of accuracy and repeatability.
