  • All of the micro metal gearmotors, except the 1006:1 variant, have the same physical dimensions, so one version can be easily swapped for another if your design requirements change.
  • Long (12mm), 3 mm-diameter D-shaped metal output shaft.
  • 4.5mm long, 1mm diameter back shaft, great for optical encoders!

We use these motors in Combat Robots, more specifically the 150gram class. There are plenty of sellers of these motors, from cheap and cheerful Chinese bulk, through to the extremely tightly wound and high end Pololu motors. The are a class above the cheap Chinese motors, and find the middle ground below the Pololu ones, for a fraction of the price. I tend to wait until the store has a discount and then buy up a few of these, as they are reliable and solid. Longer shaft than most, which is handy for some bots, but comes as extra weight. But good mid level motors, and a reasonable price point.

I bought a couple each of a few different speeds. I assumed the 1mm back shaft was geared, so I'd be able to use a normal small pinion - it's not. That shaft is attached to the motor core, not the gearbox. I expect there is a use for it, but not for what I wanted. The problem with this sort of motor is that a 3mm keyed shaft is not an easy thing to use in a model. A plain 2mm or 2.3mm shaft would be much better for driving an existing gearbox, or coupling to a prop shaft. I've seen nothing on the product pages, or in the reviews, to explain about the back shaft. For me, it's not useful and it's just in the way. I still have to find a way to drive anything with the awkward keyed 3mm shafts.

This is the third micro motor that I have bought for various applications, just as pleased with this one as I was with the previous two. I suspect I will be buying more in the future.
