EUDAX Mini Generator Motors 3V-12V DC Motor Electric Motor for DIY Toys Wind Turbine Generator Hand Cranked Power Generator Model (Plastic Motor Holder)

Great for children. Works great. Fun for kids. Nice condition. Worth the money.

I brought about 15 of these mini motors to make solar cars as a STEM project for my kids (I work at a daycare). They work very well, I had quite a few hit and misses, but these saved me from canning the whole project! They solder well, the wires are very sturdy and already have some wire exposed so you don’t have to strip them. They also run very well with a larger power source, so it won’t blow out. I put the soldered solar panel with motor outside at peak sun for 5 minutes and the motor showed on sign of weakness. I would be careful if you want to strip more of the wire, they are thin.

Not the best motors if you are wiring them to a regular usb adapter like an iPhone one. It still works for like a desk fan like that, they are pretty quiet, ready to connect.

I needed this motor to replace a motor in a cheap desk fan that my wife bought me for my desk a s this fit the bill. Smoother and quieter when the original. Torque is as original. The size was exact. Value for money is an interesting question. The fan was 5 bucks, so buying this was a bit silly. I did get several so my desktop fan will run forever.

Needed for my teen daughter’s science project. All pieces were as expected if not better, made out of great material, pieces are small but not flimsy or easily broken! Only flaw is packaging, it all came in a very small bag, almost too small, not labeled or separated as I would have liked/expected. But you get what you pay for!

I used these in a project where I needed to turn a small base with a rose on top and they worked great. They come with a holder that you can glue to your baseplate and it holds them very tightly without glue. I was surprised at the power of these extremely small units. I also like their flat profile which makes the ideal for projects where there is not enough space for the round motors.

Used it for plc project would recommend

I bought these for an AP environmental science course I am teaching. Students were studying renewable energy, and we focused on the efficiency of wind turbine systems. I installed one of the motor/generators on the tip of a wooden pylon, then stuck a beveled cork onto the shaft so the cork was able to spin freely and symmetrically. Students were able to attach airfoils (fins) onto a face of an old CD, then snug the CD hole over the beveled cork. I turned a fan on high facing the CD, and attached a multimeter to the leads. Students modified their designs to reach the highest voltage (and therefore efficiency). Although the photo I show indicates a voltage of 1.03V, students were able to generate nearly 2V with the best designs. The motor/generator shaft spins easily with almost no resistance, and even a slowly rotating shaft can generate measurable voltage in either direction. Shaft is rather small and smooth, so you'll need to figure out the best way to attach anything to it. The leads are also made of small-gauge wires which are quite delicate, but they conduct fine.

Me gusto los componentes funcionaron a la perfección y quedo muy bien para el proyecto de mi hijo.

When purchasing was told you will only get motors and motor mounts ,so i purchased from another supplier led ,fan blades and connectors, on opening the pack everything displayed was delivered,

Use el producto para un proyecto escolar con alumnos, llegó atrasado casi 1 semana, pero al hacer el reclamo me indicaron que fue el transporte, y lo enviaron gratis
