Electric Motor DC Motors Model, DIY Simple Project Assemble Kit DC 9V 12V for School Students Labs Physics Science Educational

I waited 11 months before assembling this motor expecting to be used in a physics demonstration class. It worked fine on 6 and 12 Volts. It needed just one small adjustment but it was easy to assemble. Just one of the screws arrived with a missing nut. The quality is good and I am happy with this purchase. Recommended.

Remember to not let the brushes ( the copper colored metal attached to the battery terminals) touch the same copper plate of the stator. Picture shows proper placement of brushes to start motor. Works well. Works best with alligator clips and two people to start. Could also install switch to make it easier.

Arrived in box but with a broken wire on commutator. Would be an easy fix by re-soldering the wire on to its tab but the wire wound is made from Aluminum which cannot be soldered. Ended up having to wrap the wire on to the tab instead. After the repair, its is now working.

Easy to assemble and my son built his rocket project around. Worked great until the rocket ripped it from its clamp and destroyed the plastic.

It works. It’s not perfect, but for less than $10 shipped, it’s great. It does short the battery when the motor is in resting position, so right after plugging the battery, you have to give it a little spin, and then it goes. Or you put the motor in the start up position before you plug the battery, and it’ll spin on its own. So it has issues, but gets the job of the demonstration done. The issues that it has are arguably a bonus point as a further exploration/puzzle for kids.

Great for classroom teachhing

We had to resolder the wires back on on some of the rotors. Pretty low quality but ok for students.

Motor works right out of the box with little construction. Minimum fuss...Just put a couple of pieces together and your done ..up and running. Quality parts and materials.

Worked great and easy to put together. Fun to show the kids how simple motors work.

This turned out to be a really good kit. I have given 4 stars, because the first one to arrive was missing parts. However, I ordered again and assembled it today (easy) and it works just fine. I paid $12.87 CDN., and it is good value at that price. However, there are sellers on the Amazon site that are charging far more, so be careful not to pay too much..

Didn’t expect much at this price but quality is pretty low. Two nuts missing and a wire with a broken solder that I had to fix. But it works and my grandson wants to keep it, otherwise I would have returned it

It came disconnected so it doesn’t work. It’s at the solder joint.
