I used to rewind slot car motors back in the day. We used a heavier gauge of wire and a lot less turns, then epoxied and baked in the oven at a low temp. A note of caution, disassembling the old open frame motors with the magnet on the end, can cause loss of magnetism. However the good news is that they sell rare earth magnets that will take the place of the old one, making the motor better than ever!

Thanks for another helpful video Harrison. I don't have any locos that need to be rewound, but now I know how and can give it a try if need be. You were a little surprised that it worked?!?! 😲 CONFIDENCE, Harrison, CONFIDENCE!!! Let it warm up a bit, and it'll most likely run smoother and faster, after all you did just tear it apart. I bought a set that hadn't run in years. It wasn't running very good when I put it on my layout, but I ran it forward and reverse for a bit, and now it runs perfectly fine even with a consist. It's a Life-Like diesel (Susquehanna Line). The wheels are very dirty, so I can see it running even better once I clean them. How are the wheels on your CP Rail diesel? We know the dirty track is also an issue.

You are ahead of me SMT! I have yet to attempt rewinding an armature. I would agree the main things are: to wind all coils in the same direction around the poles; & wind the same number of turns around each pole. The N scale boxcar that is laying on its side & missing a truck - you replace the missing truck with a K-D coupler & truck assembly for a " conversion car " to couple together a train of cars with both Rapido & K-D couplers!

Only read about it as there was mostly written articles. The slot car folks rewound motors to increase rpm. Don’t remember if it was less or more turns but the results were dragster type cars that were incredibly quick. Thanks for sharing 👍👍👍😎😎😎 Cary

The brushes are always 180° apart, whereas the poles are always an odd number meaning one pole is under a brush at a time, causing the next pole to be magnetically attracted to the brush forcing the armature, (with the poles attached,) to move forward, and this process alternates back and forth causing the motor to spin/ run.

Is a turn one complete wrap around a coil? So would 60 turns be 60 wraps per coil. If so in this case would a 3 pole armature have 180 wraps?
@saxmusicmail4 жыл бұрын
For slot car motors, while we wound with fewer turns (reduces back EMF) and larger gauge wire (more current) to increase RPMs, that is not necessary for model railroad loco motors. The limit of loco power is not motor RPM or torque... the pulling power of a model loco is determined by weight of the loco, and therefore traction. Don't change that. Count the turns as they come off, use the same gauge wire and wind the same number of turns back on. Epoxy keeps the winding on the armature. But also solder to the commutator tabs with silver solder, not 60-40. Silver solder is higher temp. Stay-brite works well for this. Now for the important part... a hot motor is caused by weak magnets. Weak magnets results in having to feed more voltage and current to the motor for the desired output, and this heats it up. After rewinding and assembling the motor, send it off to a slot car shop to have the magnets zapped. I use Proslot. They have very reasonable prices and fast turnaround. I work on a lot of locos, and send in motors (even new ones) 5 to 10 at a time. If a motor has been bouncing around in a drawer for a few years, get the magnets zapped. You don't have to remove the flywheels or worm gears, but do have to remove from any motor mounts.

clockwise or counter clockwise. in you case its looks counter clockwise for direction. HOW DOES THE SIZE OF THE WIRE MAKE A DIFFERENCE? and if you did one at 50 turns and anther at 51 would it make a difference? how accurate does it have to be? do the wires have to be "lapped" around each sequentially or do you just wind them any way around them? difficult to explain the question?
