Purchased this gear motor for a dc motor position control application. I also purchased a 4:1 gearset from sparkfun’s robotic section for a pot position feedback. When combined I was able to achieve a loadless position settling time of less than .7 seconds and a 50% loaded settling time of less than 1.0 seconds and less than 4% overshoot.
This motor was ideal for my application and provides torque as specified. The pot sensor I used was not supplied by sparkfun, but similar pot sensors are available through sparkfun. Very satisfied with the product quality as spec’d. Would purchase again.
