EUDAX 18 Set Dc Motors Kit,Mini Electric 1.5-3V 24000Rpm Hobby Motor With Aa Battery Holder For Stem Diy Toy

These motor sets make it so easy to assemble for projects! I use them in our workshops and they have saved me a lot of time! Highly recommended :-)

I ordered these to make 'explorer' bots (essentially brush bots, but using a cup as the based instead of a brush). Over the course of a single evening, my wife and I put together 72 of the bots using a little solder and hot glue for each one.Of those 72, only one had a problem that couldn't be fixed in under a minute - after being used by a full vacation bible school worth of kids. The one that wouldn't work is because the glue held it together after the solder joint had broken, so it needs to be resoldered.I would definitely purchase more of these for a project like this. Very simple to set-up, the joy sparked in the kids was phenomenal, and they stand up to kindergarten through fifth grade kids very well.

Was a great set to use! Bought for our cub scouts to make robots. Great deal for the lot.

I am looking to use this for some STEM activities for 4th and 6th graders at an inner-city school. The components seem well made. I do find it takes a bit of muscle to insert and turn the motor into the motor mount. I have some concern that the RPM's of the motor may be too great for a gear of pulley driven car model and have not found much that would give a good drive reduction. I have seen some EUDAX 16.8mm pulleys, but not individual sets of smaller pulley's (e.g. 6mm) .

I used these as a part of a kit for a wind turbine class for kindergartners. It worked great and was hassle free to attach the fans to the mini motor. The kids had fun.
