In 2014, I paid $29.95 (exclusive of shipping) for 20 magnets. The phone # for Micro-Mark should be: 1-800-225-1066. Now Mr. Murad, how do you like all of this specificity?

Thanx a lot!!!! Should get mine set on friday!

Hot motor + high current indicate a weak magnet.
AlNiCo magnet can be magnetized again and your motor can be as good as new.

More advice for Mr. Murad re the Pittman Motor Rejuvenation Project: Mr. Murad after you take the old magnet out but BEFORE you put the new magnets in, you should oil the rear bearing & the front bearing of the motor. I use Atlas # 191 bearing Lube (from the Atlas Model Railroad Company). Then after you put in the new magnets, clean the armature surface from crud & carbon-build-up. Clean between the armature plates using a toothpick & with Isopropyl alcohol: also use the alcohol to help clean the surface of the armature plates. Clean the brushes where they contact the armature. AND THEN, YOU SHOULD USE Atlas Conducta Lube Cleaner # 192. With the worm on the output shaft you can use Atlas # 190 Gear Lubricant or gear oil found in your local Hobby Store. If you do these steps with new magnets you will have a rejuvenated motor with 2 caveats: all bets are off if you have a broken wire in the armature windings and very little brush material left. Winding a new armature has become a "lost art," and I cannot help you there. Likewise, if you do not have enough remaining material on the brushes I do not have an alternative source for new brush material. But hopefully, you will have enough brush material remaining and no broken wires in your armature core. Good Luck! Mr. Bob.

Changed the magnets today and made some tests
The motor was clean and pretty much new.
Tested it on the old magnet:
1.78-2.01 amps on the start
0.68-0.75 amps working on idle
1-1.2 amps working with load
With new magnets:
1.24-1.27 amps on the start
0.61 amps working on idle
0.8-1 amps working with load

Right now it works much faster and really much stable!

Retooled the motor again bacause the rotor didn't swing freely.
Now THAT'S the results I'm proud of:
0.9 amps on the start
0.28-0.3 amps working on idle

Wow! Cut the amperage in half at least! That is impressive.
Did you use the Micromark magnets or were they from somewhere else?
