has any one tried the spin brush motor mod? - Page 4

Me you and Xmod supra are all testing, I will be starting in about two hours on the motor.

my gear should be here today, not sure if I will have time before the weekend to put all the motors together, but I really hope that the 12 tooth pinion will work cause it would give it a lot more topend. appearently from what I have been reading not sure if it is true or not, but the spin brush motor is a mabuchi even thought the only one that has the name on it is the cyber sonic one. I have a brooken one that I took a part, how are the turns counted? do it just count how many times it is wrapped around on the inside? do a count all three post or just one of them.

T.M.C. Motor is what is stamped on the plastic end of the Stage 2 motors from RS.

okay kool I'm going to start on the airbrushing and possibly the new motor work later on. I gotta goto work at 4 est time but I'll be here taking pics and stuff.

cant work on it till i get done work @10pm lol

Well ive been playing with it for a while, heres a progress report:

Decided to use the internals from the crest motor and the can from the xmods motor to minimize soldering. It also comes with the benifit that i can tell my radioshack buddy that its the stock motor, i dont know why yours is so slow.

So i open the crest motor by lifting the two metal taps that hold the plastic end cap on the motor. The gear slides off the shaft fairly easy, i was suprised. Pull the internal crest assembly out, set it aside.

Now i grab the xmods motor, and try to pull the gear off....no go....ok so i grab the torch (hahah FIRE!!) and heat the gear up, in the process not only did i not get th gear off, i think i flubbed it up lmao.

So now tomorrowi am going to go get the stage two motor from my buddy (11 tooth) and pull the gear off with the pinion puller my dad apparently has burried in the basment, didnt know he had one.

So, thats progress so far, probably will have a running XMOD spinbrush setup tomorrow but it IS thanksgiving so i may not get to it, but i think i will.

My paint was a failure. motor work tomorrow

As I pointed out in the motor windings thread, I don't think these spin brush motors get their power from the armatures. It's the magnets. They are thicker than any other motor magnets I have at the moment. Tight magnet to armature clearance = more torque.

sokalxballa · #54 11-27-2003, 11:51 AM

So basically you're saying if it were possible to change the cans it would change the torque, correct? Hmmm, wonder if for better or worse??

xmodsupra · #55 11-27-2003, 02:07 PM

So what your saying is that if i move the brush motor into the xmod can i wont be a big power difference because its the magnets in the brush's motor can that make it so powerful? Well ill take a break for the day then and wait for you to reply again, please if im steering myself wrong im open to suggestions.

My supra is so ugly now

So I'ma probably get right into the motor swap. I got IC3's today

. IF any can paint a supra I'll mail mine to them with some $$$. It's a glossy black now with red parts on it and the botom is faded into a speckeled red it looks like a project car. I can't wait till I can buy another one. That ones gonna just stay red but the lights will be tight on it. Xmodsupra... wish me luck I'm bout to start soldering

xmodsupra · #57 11-27-2003, 02:47 PM

I can pain it, but it could take as long as a week with my wacky work schedule and all. I'll get back to u when mine is done.

My dad said im better off to use the spinbrush motor AS IS and move all the parts to it instead of reusing the xmod can, so that the new direction. Well g'luck with the soldering, its time to drink and nail me a turkey.

neurokinetik · #58 11-27-2003, 02:50 PM

Well, I need to test this in a car, but I just swapped the magnets into a stage 1 motor, and can report that it gives the same instant response as the spin brush motor does. Rotating the motor shaft by hand, you can feel the magnets grabbing alot more than a stock stage 1. It did, however, lose some top end. I did the swap on the motor with the 10 tooth gear on it. I also was successful in swapping magnets without removing the armature from the motor can, which is huge, because the leading cause of death among all the motors I have been disassembing is the brass spacer at the front of the armature getting out of position from pulling pinions. I will do some testing on this setup later on, and then probably swap the magnets into the stage 2 can. Or else I'll go buy another spin brush so I can get an extra set of these magnets.

My stage one motor was destoryed upon trying to pull pinion. they really do not like to come off. The can was completely smashed and the axle bent. But I got it off. I used the back off my stage one motor on the SB motor to cut back on soddering. it fit nicely. then I decided to test it befor I put the last few screws in.

. It's mad acceleration and torque. IT's like a stage 7 drift motor. It was worth it. I need to test it out more tho. Watch out for my next update,

I ran just about every running surface possible. The only downside to this motor is the top end so far. The top end is not that bad but I was hitting around the same or better with the stage one. I think with topend gearing this motor should out perform a RS motor. I was able to spin the tires on every surface. {asphalt, vynil, carpet, wood and concrete. with grippy tires and against walls. It does lose any traction however on take off. The motor seems to be under some stress but isn't hot. I'm consider doing a fifth or six cell since I have an N cell holder and a duall triple A holder. I'm just waiting to do more tests. This motor has so much torque that the brakes work 10 times better so good that you can double tap the oppsite direction and spin the tires. It doesn't get stuck in the carpet as much in fact it hasn't yet. I think with ethier a cell addtion or gearing this motor it definetly an upgrade to the RS motors. Any Questions???
