torque sleeve??

[OM514]

hey guyz, i saw the thread about the torque sleeve, but i still don't really know what it is and what it does. I am currently running a Titan 12T motor in my XL5 bandit, and out of the box it has never wheelied, nor have the wheels ever come off the ground. I'm upgrading it with the Velineon power system in a few months, but for now if I put a torque sleeve on my Titan 12T will it wheelie, or will the wheels come off the ground? also, how much they usually cost?? has anyone done this with they 12T??

[tire-abuser16]

you can get them off any cheap 550 motor or off towerhobbies.com

the titan already has a torque sleeve on it.

[aussiek2000]

drop some teeth on your pinion if you want wheelies

[twonole]

Ur asking to do wheelies with a stock bandit? Is that even possible from how low it sits? Well if ur going to try put a 25 or 26 tooth with a pretty tight slipper good lock.

[tire-abuser16]

noooooooooo thats a good way to fry the motor... put a 16 tooth on it

[Matt24138]

the 12t titan has a tourque sleeve on it i believe. i can get my stock rustler to wheelie every once in awhile dont know what the difference would be

[twonole]

noooooooooo thats a good way to fry the motor... put a 16 tooth on it

Noo because of how small the bandits wheels are it would be in the range of the mid 20's.

[slowenuff]

Everyone answer his question cause I also want a definitive answer on what a torque sleeve does.

[OM514]

i'll try a smaller pinion. by the way, i'm not running on stock gearing. my gearing used to be 26/76, but now its 23/86

that is still over geared..

[lilrichie1306]

nah bro for a bandit if u research it runs like a 28 tooth pinion out of the box [or a 25, i cant remember] compared to the rustys 23...... all due to the smaller tires. But a torque sleeve is simply a metal band that fits right around the outside of your motor can. It traps in magnetic flux [in a concentrated space] and in which produces more torque. I have not seen any top end loss with it........... i hope that this is sorta good of an explination.....

EDIT: Oh and also, the Titan 12T comes stock with a torque sleeve, but to really see wheelies you might have to gear it down to like a 18 tooth pinion for a rusty and maybe a 22 or somethin for a bandit :O idk tho dont quote me :P and also make sure that u have good traction, that is KEY more than anything else, i cant wheely too good with the stock tires on pavement, but i flip inside my house i wheely so big!! so that is the key in terms of wheelies!

lil richie are u signed onto rcu right now?? check my electric buggy thread there

In a nutshell:

A torque sleeve enhances the magnetic field of the motor. They are often used on motors with thin-walled cans. Anyway, the stronger magnetic field results in an increase in torque and a decrease in rpm.

[rusty nail]

Oh, I didn't know it would decreas RPM's at the expense of better torque. How much does it decrease the RPM's?

[slowenuff]

Thank you razer for being the only voice of reason. Now what would be the effect on a brushless motor.

[marktheshark]

So, is this torque sleeve just a very thin flexible magnet that gets wrapped around the can?

I'm not sure. A BL motor is made differently than a brushed motor. The magnets are part of the rotor instead of lining the inside of the can.

No, it's just a thin ferrous metal sleeve.

I'm not sure. A BL motor is made differently than a brushed motor. The magnets are part of the rotor instead of lining the inside of the can.

I'm guessing that despite the magnet being farther from the can in a brushless motor (IE- in the middle instead of on the can's walls), the torque sleeve should still help the motor create more torque.

The windings on the inside of the brushless motor are simply electro-magnets when they're energized, and produce a magnetic field. I think it'll have an effect; the question is: "How much of an improvement in torque can we expect?".

I kinda want to try this, but that means I'd have to look in my messy room, order one from tower, or pillage a power tool that is still useful. None of the three are going to happen...

[slowenuff]

Ferrous hmm I like that word.

I doubt there would be much change in a brushless. A brushless is basically a very small three phase industrial motor. The windings around the can are energizied in a "one after the other" order, this produces the rotating magnetic force to move the motor shaft(more commonly called the rotor). the faster this energizing of of the windings occurs the faster the rotor spins. Thus doing anything to change this magnetic field is going to upset the dynamics of the design.

[tire-abuser16]

Miggles, i feel your pain, i have only worked on rc since school let out take a look




a rustler, a brushless conversion 1/8 scale, and 44 cells..

[highster]

a brushless conversion 1/8 scale, and 44 cells..

Wow your gonna need a HUGE motor to carry 44 cells around.

[tire-abuser16]

Wow your gonna need a HUGE motor to carry 44 cells around.

noooooooooooooooo, im only gonna run 14!! lol
i have 44 cells total...
i have a nemisis blue 9xl


sorry for the off topic

I see your point, although increasing the magnetic field shouldn't hurt things; it should just lower RPM I would think (Novak's rotor upgrade increases magnetic strength, and hasn't messed up their motors with the original design- of course, that's a rotor, not a coil being energized many many many times a second). I wonder if it'd affect a wye wound motor more than a delta wound motor though, since the wye wounds have two thirds of the coils energized at any time compared to a delta wound only have one third of its coils energized.

tire- I'm going away to college this Thursday, so the Rustler is all packed away. The only RC that isn't packed away is my brushless+lipo Micro-T. I'll still get an RC fix while I'm away..... Now I gotta go pack all my clothes away....ack! It'd be quite pointless for me to order something when I'm not going to be here to receive it...lol!

I agree the way to get more out of a brushless, is to get more magnetic strength into the rotor. It would appear that Novak and others have found this to be true also.

I'm awaiting the 14mm sintered rotor from Novak (if they ever do it). The "normal" sintered rotor is 12.1 or so millimeters. The new tuning rotor is 13mm. A "regular" bonded rotor is 14mm (so that's about the max diameter that'll fit in the can safely)... I want torque!
