This is a tutorial on how to make a powerful dc brush motor. The first step is to get the parts. You will need a 12 volt battery, a motor, a switch, some wire, and some connectors. The next step is to assemble the parts. Connect the battery to the motor with wire. Connect the other end of the wire to the switch. Connect one end of the switch to the negative terminal of the battery and connect the other end of the switch to the positive terminal of the battery. Finally, connect the connector to each terminal of the motor. The next step is to test it out. Turn on the switch and see if it runs. If it doesn't run, check your connections and make sure they are all secure. If it does run, congratulations! You have just made a powerful dc brush motor!

From what I see in this video here is my opinion thorough observation.
1. The winding of the armature seems to be wrong as the " two windings were wound to cancel each other's magnetism.
At 1.50 that half of the winding is clockwise, while at 2:13 the other half of the winding is also clockwise when it should be anticlockwise to produce a stronger armature winding. It seems that the motor is running due to the difference of the winding in the half windings of the armature!!! It would be a stronger motor if the armature had a normal wound could with cumulative halves and not differentiated halves.
2. In a DC brushed motor the magnetic field changes polarity and so the armature iron core is subjected to reversals, hence eddy currents in the magnetic path. This bolt is not laminated and so the eddy current effects will be substantial and they will delay the reversals and I do not think it will be able to rotate to 21, 000 rpm as claimed.
3. At 3:03 the manner in which those two segments of the commutator were glued to the shaft means that the shaft needs to be of high resistive material as otherwise there will be a short circuit across the segments. Those two segments in the commutator should have been better insulated from the shaft and each other.
4. The spring brushes are a good design and it is surprising that they are not sparking more than they are. The power supply seems to be currently limited or a current source.

Your invention is millimetrically perfect. Congratulations from Brazil!!!

It's about 10, 000 RPM.
He measured the RPM at the place where 2 bolts were were spinning one after other making counter count one spin 2 times.

You did a great job Einstein!
We need to move forward with the idea with bigger capacity!

That song is the most annoying thing I've heard in in my life.

This is the principal of electric motor
Awesome bro

[aldolajak]

I'm going to make one of these, I hope it isn't too powerful for my 160 ft yacht, I don't want to exceed 80 knots.

21000RPM / 2= 10.000RPM because in 1 revolution 2 bright surfaces and 2 yellow (coil) surfaces were in the path of the laser.
The official measurement is 1/2 of the axis in black or matte and the other half in white or shiny.
The laser then detects a change of 1 signal per revolution.

Cool. One thing I would have balanced the armature, it's easy. Glue 2 single edge razor parallel with enough room in between for the arm and balance.

Their projects are good, but stop presuming that you have the materials at your fingertips for those who do not have them

would love to see that done with a three phase setup

I love these mechanical videos, but god the music makes me want to jam the heating iron in my temple..

[zenonbiusz]

21000 RPM - my ass...
powerful motor... 1 W? 0.5 W?
Shitty noice, it could not be called a music.

[josephstalin]

Pretty decent design actually, from the looks of it...

More like 2100 RPM, I wouldn't to be standing near this thing if it were capable of 21000 rpm. But I and my 5-year-old had fun making one of these at home. She wants to build robots, so we started with a simple electro magnet, a simple single coil motor, and then this one. Next we will make our own battery.

aaaagh!.. the music is giving me head cancer..

[mazhartila]

RPM measurement is wrong. your motor has a lot of reflecting surfaces which give multiple pulses per turn, which multiply one turn into many turns.
