These GM3 - Gear Motor 3 - 90 degree Shaft are very comparable to a hobby servo for power, at a fraction of the cost! Fit perfectly with GMPW and GMW plastic wheels.

This gear motor rotate 360 degrees every 1.6 seconds (just a hair slower than a servo), at 5V, drawing 600mA at stall (free running at 52mA). With a 7mm double-flat output shaft (avoid using the "D" output - it's not meant to take rotational load), and a built-in clutch (limiting at 60 in.oz, but easily "locked"), and built-in mounting screw holes, you can see why we like these motors!

Based on the original design by Mark Tilden for use in the B.I.O.-Bugs (GM3 are now used for use in the Robosapien), these motors are the next generation with a variety of improvements such as dual output shafts and a lower current motor.

GM3 - Gear Motors are compatible with the Solarbotics Wheel Watcher Rotation Encoder. Use it if you need to control a robot for dead reckoning, tracking odometry (distance traveled), stalled motor, or closing the feedback loop for position/velocity/acceleration.

Great little motor...

I am using this geared down motor for UGears Theater module, so as to animate it when the detector is actuated, using an Arduino Nano. The gearing ration is perfect for the use. Had a problem mounting the motor, but all came out well.

Excellent mais...

Acheté ceci en remplacement des moteurs jaunes à 90 degrés que j'ai sur un robot, sur la base des conseils offerts dans les pots de ce forum: https://www.robotshop.com/community/forum/t/moving-from-cheap-yellow -motors-to-low-cost-dc-reducteur-motors/25901. Les conseils me semblaient authentiques et semblaient faire autorité (comme s'ils venaient de quelqu'un travaillant pour Robot Shop). Lorsque les nouveaux moteurs sont arrivés, ils s'insèrent en effet exactement dans les mêmes supports que mes précédents moteurs jaunes, mais l'arbre de transmission est d'une taille complètement différente, ce qui signifie de nouvelles roues et de nouveaux pneus. Maintenant, j'ai fait qu'ils font du bon travail, mais ils ne remplacent pas directement.

Probablement mon erreur

C'était une teinte plus grande que prévu et la descente dans l'engrenage était un peu plus que ce que je voulais ... j'aurais probablement dû lire la description plus attentivement. Mon ignorance à part fonctionne bien même si les contacts sont un peu fragiles ... allez-y prudemment car ils se plient très facilement.

Probably my error

Was a shade larger than expected and the step down in the gearing was a little more than I’d wanted...probably should have read the description more carefully. My ignorance aside works well although the contacts are a wee bit flimsy...go carefully as they bend very easily.
