Im soo confused

What does touqe mean?

I thought more torque = more speed

So max speed will be lower turns. but will it have slower acceletation?
Max tourqe will be faster Spinning but will have lower speed?
Is this Correct?

I want to build 3 motors: SUPER Torque, Super Speed, and Balanced...

Ooh, that's a good find. Cheaper than I've been able to get a BB can and Neos separately. I may have to stock up.

Don't bother with the Squat Neos. They are really only good for sticking your screws to when you dissassemble the car. They made no difference in performance for me.

Lastly, the combo that I talked about in the other thread (stage 2 arm reduced to 44 turns, timing advance, BB can with Drac's Neos) works quite well and does most of what you were looking for. Excellent in the midrange, top end is about the same as a good stock stage 2, enough torque that I can use it on a tight course with the blue gear set. Surprisingly, the Neos taking away the ability to coast was not an issue in the AWD car. It just meant I didn't have to brake going into corners, as the car slowed down pretty well on its own.

well... I decided that the 43 turn was fast but not enough torque for my liking. It was great on straight-a-ways but not good for short distances... so I wound a 50 turn with 30gauge and omg... though it doesn't have the top end of the 47 turn or the 43, it has gobs of torque compared to the 43 turn and niiice increase in comparison to the 47 turn Stage 2 armature. Now, this is important to me b/c I'm building a little drift car for cement, so I need lots of torque to break the tires free. Depending on how the new 50 turn works, I may or may not try to make a 53 or 55 turn motor. We'll see!

Try some Neos if you want torque... They make the blue gear set usable.

Or, alternatively, you could try something like this:

The top armature is from a stock Micro RS4 motor. (FK-180 style can) The bottom one is the 130 type that we are used to seeing. Given the same number of turns, guess which one will have more torque?

Anyway, I realize I'm not the first one to try a 180 motor, but I think I will be spending more time on these motors than 130 style, as they definitely have alot more potential. Oh, and I think I set a new record for shortest time between buying a new motor and disassembling it... :lol: I think it was out of the package for about 5 minutes before I was working on getting the endbell off. These are a bit tougher to open than 130's.

Well I wound the 54 motor and during the break in, it was a bit odd... it'd periodically stop, as if there wasn't enough power to get it moving, then when I spun it real quick it ran with tons of torque... then I ran the motor off of the xmod circuitry and after about 5min at full throttle, the underside was real hot... this doesn't happen with either the 47turn or the 50 turn. We'll see though. I'm starting to think that the 47turn and 50 turn setups will be my primaries when I get my Yeah Racing cans.

I just reduced a stage 2 motor to 42 turns, and did the timing advance at the same time. Doing the timing advance at the same time as the wind reduction works nicely as you create slack in the winds when you advance the timing, but when you reduce the turns, you can take that slack back out. I didn't change magnets this time, as I am really looking for top speed on this one, and the spin brush magnets hurt the top end.

Anyway, this one needs to be tested in a car, but it sounds hella fast and smooth. Probably my best effort to date. Even compared to my best stage 2 motor in the latest pack I bought (which, out of the box, ran much faster and smoother than the others) this motor sounds way better. Unlike the 25 turn experiment, it doesn't take all day to reach top speed either.

One other thing, I was looking at the armature from the 180 can, and noticed that the brushes and timing are done much differently than they are in the 130 motor. It needs to be wound differently, and I'm probably going to hold off on doing timing tweaks for a bit until I fully understand the differences.

timing advance?
i know these are a lot of newbie questions but could you explain
?

neurokinetik · #23 12-14-2003, 05:38 PM

There is already a whole separate thread about it. Do a search.

SuPrBuGmAn · #24 01-09-2004, 06:32 PM

How few winds can you get away with without a timing advance and without a mosfet upgrade?

With stock S2 mags and with neo mags, if you guys don't mind.

neurokinetik · #25 01-10-2004, 12:32 PM

42 turns seems to be safe on the stock ESC. It draws about 700mA, with or without Neo magnets.

First time unwinding the motors.

I'm having trouble getting the comms to let go of the wires in the FF180SH and S2 armatures(Spinbrush comms are simply soldered). The S2 and MB(Motionbrush 180) comms seem to have the wire hooked in a bend of copper. However, even with a small jewelers flathead, I'm having trouble getting the comm to let the wire free without breaking it.

Any helpful hints? Am I missing something completely? LOL

Thanks.

I've been just cutting the wire, then soldering it back on to the top of those commutator contacts.

how do you count the turns/winds? i've search but i still cant find anything. im a newbie to winding motors

GaryMan · #29 01-11-2004, 03:18 AM

you count as you wrap, and as far as know stock turn numbers people just count as they unwind

SupraDJ · #30 01-11-2004, 03:42 AM

so everytime you wind back to you starting point. thats one turn/wind?
