Retired RETIRED

This product has been retired from our catalog and is no longer for sale.

This page is made available for those looking for datasheets and the simply curious. Please refer to the description to see if a replacement part is available.

Replacement: ROB-11696. Our new Hobby Motor now comes standard with a 6mm, 10 tooth, gear. Go check it out! This page is for reference only.

Description: Here is a basic hobby motor. It works well for basic things like making a fan or spinning something very fast without much resistance.

The motor has an operating voltage range of 1.5 to 4.5VDC and a no load speed of 12800 RPM (@4.5VDC, 320mA). More information is available in the spec sheet linked below.

  • A reminder/warning to anyone who uses these… They don’t come with ‘snubber’ caps to get rid of noise spikes. Looking at the inputs on a scope shows ~+-50v noise when these are run at 4.5 volts, less when run at 3V. Try .5uf 15v or greater across the supply terminals. If you’re driving this with something that’s sensitive to negative voltages, consider a snubber diode as well.
    Be careful with grounding and how you separate your logic supply from the motor supply.

  • I am perplexed by the datasheet. The description above says “12800 RPM no load speed”, but the datasheet says (in sec 2) “no load speed 147.6 RPM” and (in sec 3) loaded speed of “118 RPM”. And THEN, below that in sec 5 it claims 15000 RPM!
    So which is it?

  • These things are awesome i bought 3 or4 of them

  • I’m considering using a couple of these in a prototype, but I’m not sure how I would go about attaching this motor to my robot.

    Does anyone know of a good way to mount these?

    • sparfun sells a motor bracket that may fit these

    • I’ve just begun using motors and I too would love a good explanation of how people use these smaller motors. The only ones I get at this point are ones large enough to have a gear and set screw.

      • a plate metal piece with some holes drilled in it and zaps straps is mildly effective. the best way is to get a specially made mounting bracket

  • How can we use the shaft? does it come with gears? pulleys? If I need a custom gear or pulley size, is there a way for that??

  • SparkFun, Please help, this part is vital in my project, I need it before (June 20,13). I see it is sold out but can someone let me know when this part is coming back in stock. It would be a huge help if someone can tell me how long it take for this part to come back in stock.

    Thank You

    • We are working on it, but unfortunately are still waiting to hear back from our supplier on this motor. Until we get more info from them, we can’t give an estimated time for this being back in stock :/

  • I have always loved these devices, but a warning to anyone who might buy: They come presoldered with extremely flimsy wires, and I have had both of mine break off within 5 minutes of unboxing. I am not satisfied with this quality.

  • very good, and cheap motors at this site. same ones used for outdoor animated deer. http://www.kindys.com/products/decorating-accessories/replacement-parts

  • The leads on these come off pretty easily. Mine usually break after using for about 30 min. No big deal though, for only $.95, what do you expect? Just an FYI that you might have to get the soldering iron out.

  • Anyone know where I can get the pin-out connectors shown in the photos? I want to use them with a few projects where soldering wires for breadboard use is a bit difficult.

  • The motor in this listing does not have a mounting flange. In the datasheet there are 2 holes, 11.5mm apart, but they are not threaded for fasteners.
    For my application I can work around this, but this is just FYI for others…

  • I swear my entire childhood was built using these.
    How many toys did I dismantle and remove them from? I cannot remember. Looks like its the exact same shape!
    Just the little plastic gears missing :p

  • Alright, I am a “newbie” in robotics and I just want to make the most simple helicopter ever. That is all, all I need is a propeller, and how much weight this guy can handle. Thanks!

    • A little late, but its a lot more complected figuring out lift than just attaching prop. Just for starters you have to pick the right prop pitch and diameter.

      • Agreed. I know from personal experience that it is Very difficult to get anything off the ground. I would rather doubt that this motor can even lift it self, even with the most efficient prop pitch/length.
