Neo Magnets

[Draconious]

Any one try my Mini-Z neo magnets in an X-Mod yet? -- curious if it fries, works, works better, works like crap, etc.. (gain will be torque not RPM)will need bigger pinion so far as I know its a hard thing to do in the X mod...

[neurokinetik]

Well, I have a set of them, and tried them with my X Speed motor in the Squat ball-bearing can. I couldn't tell the difference. They work great for keeping all of my screws together though.. :lol:

[neurokinetik]

I didn't read your post properly the first time. Let's try that again...

I tried the Squat Neo Power magnets. Not the ones that you have that replace the magnets in the motor can. (Had I known about those when I placed my order, I would have went with them instead. )

I'm going to attempt to mount the Squat magnets directly in the motor can instead of outside, by sinking them directly into the stock magnets. It's worth a try...

Then I'll probably order a set of your neo magnets.

i created a mini-zracer a-bb monster motor using drac's neo magnets. i sue this motor only in my monster pajero overland as it has enough power to climb just about anything. it is about as fast as a sotck mini-z motor but almost unmanagable power. my pajero will wheelie from a dead stop! well, mostly it will completely flip over!

if your looking for absolute brute force, these powerful magnets will do the job, provided you use an fast armature and a bb can. this combo is not for racing. you will drag, push and generally bowl anyother xmod over though. the amount of power it gives you might not be good for the cheap gearing (from what i've read) though. it can and will strip gearing in overlands and racers.

just to give you an idea of how strong they are

[neurokinetik]

Well, they might be just the ticket with an AWD setup and the highest gearing available. That's the kind of setup I want. I used to use a motor made for a 4wd offroad car in my pan chassis RWD 1/12th scale. It took alot of finesse to come out of the corners straight, but the amazing acceleration made it worth it.

I've got a set on order, we'll see how they work.

so the magnets that aren't mounted inside the can is mounted outside on the can? would the steering magnets from bits work? they're pretty strong. or howabout those magnets in hard drives that move the arm? those are incredibly strong.

[Draconious]

LOL might help if I came back to the thread I started, been busy messing with new PC, converting files etc.....

Any way, the squat magnets are literaly useless... you might notice a .001% difference... as for hardrive magnets, my magnets ARE the type of magnet used in hard drives... although some drives use similar but not the same type... they are stronger cuz they are larger... the more magnet you have the stronger the magnet of course... reason the squats are useless, they are too small, and too far away from the armature, and have to go through a piece of metal (the motor can) to get to the armature by the time all this happens there is virtualy no magnetic field left in the armature...

I only got these magnets to resell for the Mini-Z, cuz of the squat magnets being so weak, useless, and expensive for the cost, I set out to find the same magnets cheaper, and wound up getting entire magnet replacment sizes for the same price, and still cheaper then the squat disks were when they first were released (about $12 for squats back then).

In the Mini-Z X-Speed, my neos will DOUBLE the torque... but the RPM will drop about 25%... if you play with the gears you can either trade the torque for RPM, or just keep the torque.. as is, depends on the use... but if the x-mods gears are weak (i have not even seen an xmod offline yet), then it might be a bad idea.. lol.. unless alloy/nylon/delrin gears come out...

I rate them as being able to hold 1 pound... but this is to a small tiny contact patch to the magnet, if i were to maximize the contact patch to the magnet/item its holding, I could do well over 5-10 pounds.. with ONE magnet in the pair... they are Gauss: 12600~12900 or Tesla: 1.26~1.29 ---- it takes 1000 Gauss to erase a credit card... lol (going by that myth busters episode).

[TypeZer0]

is it hard to swap the magnets inside the motor? do you still sell these magnets? when you said squat magnets, did you mean the steering magnets from the bits?

[Draconious]

The squat mags are simlar to the bit-charge mags... just differeind diameter/thickness...

I realy dont recomend anyone that has not opened a motor can to install the magnets them self... its usualy a pain the first few times... just to open it. let alone keep the motor and capactior wires from breaking, brushes from bending, and bushings from missaligning...

[neurokinetik]

Actually, I've noticed some things while opening and closing motor cans and how they apply to a Neo magnet.

It is better to desolder the capacitors on the terminals than the can. This way the endbell can be removed completely without exposing the magnets to the heat of the soldering iron. It is much easier to work on the motor with the endbell completely removed, and I think with the strength of these magnets, I'm going to want things to be as easy as possible.

It may be a good idea to affix the first magnet to the can with epoxy or some kind of strong glue, that way the potential for it flying across the motor can and impacting the other magnet during installation is lessened.

[arch2b]

actually, the way they are situated, they repell one another so they slide right in and stay put. the most difficult part is getting the retaining pin back in.
i removed the bell cap as this did make things easier and the heat from a soldering iron is not good for the magnets. that's was drac's suggestion.

you MUST becareful with these magents. they will fly across the table or even pull things toward them! if they hit eachother, it will likely break them.

good luck with you neo xmod motor and give us a review of it's performance

[Draconious]

Yep, I have about 8-10 broken pairs now, cuz cuz I keep grabbing a pair and playing with them... eventualy after flipping them pulling them apart a few times waiting for files or in chat rooms etc.. they break , usualy when I show them tos ome one else I wind up breaking them lol... I should problysell all the broken ones for something

If I were to install a pair into an X-Speed I would not need a soldering iron.. to do it . unless I hapen to break a power or capacitor wire...

I usualy remove the end cap, by seperating it from the brush holder... then I bend the capacitors up, bending their wires, doing this too often to a capacitor WILL break it sometimes just once... then I remove the armature, swap the mags bend the brushes back down, make sure the brushes are siitting as good as possible... then I put the plastic end back on...

The trick/problems to X-Speeds is the metal bushigns on the shaft, if they are not inline once the motor is reassembled the armature will drag on them... eating at some of the torque, this is why I prefer bearing cans... but even then you need the bearings inline.. just does not have to be quantum accuracy.

[neurokinetik]

How long should it tak for me to get these? It has been over two weeks since I ordered them.

BTW, I have learned to swap magnets with only the removal of the endbell now. No despoldering, no removal of the armature or pinion. Piece of cake.

[arch2b]

shouldn't take that long......email drac, he's also on aim alot with the same name. i always got stuff from him in a very timely manner

[neurokinetik]

Got my magnets today. I can't believe how strong these things are! Too strong, actually. I tried them in my 25 turn motor, and it won't even start spinning unless I give it a little push. Once spinning, it now only runs the same speed as a stock stage 2.

Time to get back to experimenting. I'll probably throw them into my X Speed next. I'm running out of stage 2s that still have their original armatures intact, and I like to keep one stock, just for reference.
