school project for yr12... Commutator DC Electric Motor... very simple motor just to show how electric energy can be transformed into mechanical kinetic energy...

Some Info:

- External Magnetic Field: is supplied by two strong Earth Magnets.
- Power Supply: four AA batteries.
- Armature: is made out of plastic tube with wooden axle going through the centre of it.
- Coils: (simple electromagnets) are made by wounding very thin laminated copper wire around a screw. Each coil has around 500 turns, wounded in the same direction.
- Split Ring Commutator: is made out of three separate metal bars, placed around armature with small gaps between each bar. Each of the coils is connected to a pair oppositely placed commutator bars. So when motor rotates torque is acting in the same direction.
- Brushes: are made out of copper wire, suspended tightly around the split ring commutator. For better performance and minimal sparking you should use carbon brushes with small springs, but for such project simple copper wire will do.

Mark:

I got 9 out of 10 for this project.

  • heres an idea, why don't you actually explain something about what is going on in the video instead of making another crappy Music video like everyone else on you tube. What is with you people is it a competition or something to see who can ruin a video the most by turning it in to a lame music video? please explain i want to know why you did this? it would have been better if you even left it silent.

  • the music is pissing me off! :P !

see all

  • how did you attach the wires to the commutator and did you strip it of the insulation before connecting the wires to the commutator?

  • can somone plz explain me wat is need of carbon brushes in motor ..........i never get it

  • WTF MARIO MUSIC!!!

  • Remember when......lol

  • What materials did you use for this? I have to make one of these for physics, and I can't find anything.

    Oh, and my prototype's armatures don't seem to be wired correctly, do you think you could tell me how yours is set up?

  • What is the piano song at :59?

  • What did you use for the 3 commutator bars?
