Customer Comments

  • Is there a published MTBF for this product? I know it has metal gears, but the material the gears is made from won’t matter much if there’s a bearing failure. My application would have this running for weeks at a time 24x7 at the fully rated voltage. It’s not a high torque application, if that makes any difference. It’s running a magnetically coupled stir bar which slowly mixes a fluid in a container above it.

    Anyway, I just finished building it and was curious.

Very good gear motor

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.
