Motor help needed

So my question here is: can i replace the magnet block (or is it a piece of steel or iron that has been magnetised??) with a new magnet, to get more power out of these old motors, and will that keep them cooler??
Or is there another, proper fix for these motors?? Thanks, Glenn

Could be not enough amps! Could be
the motors were disassembled and the
magnets removed, this will weaken
the motor. Are all the windings
attached? If the motor were cleaned
with a wirewheel or brush the wire
to the arm can get knocked off.
If the Atlas came from TigerTom,
some were cleaned with a wirewheel
and I had one that needed reattach.
And then you have the controller?
You need 10 ohm or lower. And 3 amp
at the transformer.
I think taller gearing may help too!

In case you're wondering, I want to be able to race the 1/24 Atlas Lola and Ferrari against Coxs and Tamiyas. I see RE mags as the only way to narrow the performance gap.

Of course the Dokk is right as always-make sure the bearings are oiled and do a slow break in at 4 or 5 volts for 10 minutes. One other thing- I assume your Atlas motors are the AT-206 (6 volt ball bearing) or AT-208 (8 volt plain bearing) and not the AT-406 which was made for the 1/24th scale cars mainly, however the 1/24th Formula cars did have the AT-206. The AT-406 has wider magnets and the neodymium magnets sold on Ebay may not fit. I have not tried comparing them yet.
STEVE- It won't matter on the orientation. If it isn't right just flip it upside down!

Let us know how those magnets go. Pity they don't fit the 406, as that's the one that needs te most help!

Hello. I'm an Altas motor fan. I have read about the AT-208 and AT-406 and I have a few of them, remagnetized, ready to go into 1/32 slot car chassis and a couple of 1/24.
However, Im have having trouble with giving one motor a tune-up.
I bought an Atlas tune-up kit off ebay. Each spring allows the carbon brush to fit inside, but the springs are too wide to fit inside the brass retaining screws.
Wanting to know why, I pulled down another one of my Atlas motors, which has thinner brushes.
Can I drill out the brass retaining screw so that it will accept the spring?
Otherwise, where can I find a pair of new replacement (thinner) motor brushes?
If anyone can tell me the names of each Atlas motor I would appreciate it.
I'm curious to know why Altas changed the brush size width? The motors sure looks the same.
One more question, if I may. I have an armature with green wire. What is the difference between that and those with plain brass wire?
Thank you.

First of all, these old inline motors use "Alnico" magnet material. Invented in the middle ages for many uses. It has bad memory and needs to be recharged now and again. Ceramic magnets were not invented (or at least in common use) before the early 1960s. The rare earth magnets are much newer as well, but do have better memory of their fields
