Short Tutorial On Dismantling DC Motors
« on: July 15, 2010, 12:52:49 AM »
So I was getting board today and had a little motor lying around, so I dismantled(say: destroyed) it and wrote a short tutorial of what to do...

TOOLs:
small 1mm screwdriver
motor
time
needle nose pliers(optional, but recommended)

METHOD:
1.Find your victim(motor), mine was a cheap one from a $20 RC car
The victim:

2.Open the motor by bending the two metal tabs(located around the edge of the metal cylinder)away from the plastic "cap" thing with pins sticking out, I used a 1mm flat-head screwdriver.
3.Lever the plastic cap off.
4.Inside there should be a little shaft with electro-magnets(mine had 3).
Step 4 picture:

5.Pull this out with your fingers or the needle nose pliers.
Step 5 picture:

6.The only remaining part should be the permanent magnets these are glued in >:(
7.You have successfully dismantled a DC motor.

You may wish to savage the coil wire, magnets ,etc.
  
Please +1 my "helpful" tab if this helped you!

Oh and just to amaze you even more:
I put the motor back together(temporarily), and it worked fine, actually better!
I am amazing! 8)

UPDATE...
I figured out how to remover the permanent magnet,
use a vice/clamp or pliers to squeeze the motors metal body.
The magnets pop out, along with two metal U things that hold them in place.

Hi,

So I was getting board today
Carefull, boards get nailed  ;D

Try using a tripod or similar to avoid blurry pics (Pic #2 from the top is shaken) - shorter shutter times helps too.
Perhaps you're too close for the range of the cam or the setting is out of focus - does the cam has a manual distance setting?
Which cam(s) are you using?
Add lots of light, digicams like that.

This is a couple of handheld shots in less than good lightning:


Regards,
Søren

A rather fast and fairly heavy robot with quite large wheels needs what? A lot of power?
Please remember...
Engineering is based on numbers - not adjectives

I'll take better pictures when I have time, what SoR needs is a tutorial on taking pictures...

Would a picture-taking tutorial which includes somehow using an Axon be in the running for an award? ;D
