what i but the mags into the top speed motor. will that equal out or still kind of stink. what if i put it in a drag motor.

Neos would probably help a bit with the torque, but it would ocme at the expense of a little of the top speed.

meteoraclown 04-06-2004 07:33 PM

ehh. i want some neos for 180. might go off topic but if i get the team orian stock how many windings should i drop to.

Motor Frankensteins
 
Nobody has addressed the actual mechanism by which these motors work. (See no cussing so far. Add those words freely in your own mind.)
By using NEO magnets one increases the magnetic field in the can. This increases the "push" on the motor armature, spinning it faster. Everybody with me so far?
The increased spin causes an increase in the reverse voltage in the coils, slowing them down but torquing their coils to the max. Somebody was right when they said that magnets and armatures that are fitted to each other are the best.

part deux
 
So, add these new hot Spaceman Spiff magnets and get a slower motor. True. Very true at first. But you have to buy 4 motors at a time from RS. Buy a new set.
Its trashing time! Grab a beer, lock the old lady and kids out of the shop, put ACDC music on..(But I digress)
Get a few of the BB cans from minizracer.com or others.
HEY TINYRC, WHY DON'T YOU SELL THEM HERE?
Get the can caps from Tiny. 4 to a pack. These are not ceramic. They are epoxy and take heat better.
Take your stage 2 motor apart carefully. Notice that the brushes are flat, not rounded. (Add cuss words here) (again). Back to this later.
You didn't remove the caps from the can did you? The bell housing separates from the brush housing. Carefully bend the brush housing back without disturbing the brush arms.
Remove the magnets. Put them back in. Do this a few times until you are comfortable installing and removing magnets.
You may open the second beverage now.

Feeling better? Too bad. Continue.
Now we will start.
Put Crest Spinbrush magnets in this 1st try.
Take a BB Can. Install 2 of the can caps. One each where the RS caps were. Only solder the can side of the caps. Rub silicone spray on the backs of the magnets. Lube the bearings. Install the magnets, armature, and brushes. Spray the armature with Trinity Armature lube. Close the bell housing without pushing in the locking tabs. It should hold together. If it doesn't, tape around it with clear tape. This is very temporary. Test the motor to see if it rotates in the right direction. If it doesn't, swap the magnets. That should be easy for you now.
Now you may close the tabs, sealing the motor against further concerns (You have 3 more)
Carefully run the motor at 1/2 voltage or less for at least an hour to conform the brush heads.
I prefer the water method. 'Search' these methods. I won't get into them here. After the brushes are broken in, solder the caps, the electrolytic cap across them and the motor wire. Try running it. You should like your first motor rebuild.

THE PINION GEAR!?!

Oh yes, use a gear puller or a torch to remove the pinion gear. Put it back on with a hammer.

I haven't touched the armature rebuild yet. I need a beverage.

cool 8ooth post in this forum

i didnt feel like readin all that stuff does it workinx mod motors.
i plan to put them in my yellowstage two motor(10 teeth):D

baleisen 06-12-2004 07:40 PM

It works very well if you properly break in the motor. Make sure that you buy a ball bearing can like Squat sells through Tinyrc.com
BAE

edizzle 06-15-2004 04:33 PM

wat would happen if u dont get a berring case???

baleisen 06-15-2004 08:20 PM

You won't get the best benefits per cost. The can now comes with carbon brushes. Do a good break in and you will be happy.
Don't and you will be sad in a couple 100 yards of running.
Remember to advance the timing, too.

edizzle 06-17-2004 05:34 PM

im not exactly sure wat that means??
umm please explain the timing and how to break in and other stuff pleaz..

baleisen 06-18-2004 12:04 PM

OK. Buy a squat motor can with bearings from TinyRC. Get 0.1 uF ceramic capacitors from RS. The timing change is documented on www.atomicmods.com (I think. Somebody will correct me if I am wrong) Break the motor in by hooking it up to a power supply set at 3.0 volts. Have the motor outside of the car so you don't wear the gears. Run it for 1/2 hour to set the brushes.

edizzle 06-20-2004 10:22 PM

ya so far these magnets suuk every way i put them in my car goes backwords?????
yyyyy:confused:

baleisen 06-22-2004 07:26 AM

Reverse the positive and negative leads to the motor.

edizzle 06-22-2004 12:23 PM

i wish i new what that meant??????/
:confused:
