MOTOR TURNS

my friend thinks that the more turns a motor has the more torque it has and the less turns it has the more speed it has. i know that lower turn motors are more torque overall but he won't believe me. can someoone help me out here? maybe he will believe a traxxas employe? please help!

Quote from misbehavin' rc"

Turns is the number of times the wire is wrapped around the armature. Lower-turn motors turn higher RPM's, and can give you a higher top speed. However a lower turn motor will also drain your battery pack faster giving you a shorter runtime.


Winds refers to the number of wires that are wrapped around each leg of the armature. A lower wind motor, due to inertia properties, is much easier to start turning. Therefore a low wind motor offers more low end torque. A higher wind motor offers more torque at the upper end of the RPM range. This is due to the fact that the extra winding helps keep the motor spinning once the armature is set in motion."

Hope that clears it up,yes you are right, now you can make fun of your friend because hes wrong.

Actually, he's more right than you are.

A higher-turn motor has more starting torque than a lower turn motor. A lower-turn motor can reach more RPM's. Since Horsepower (or watts, for electric motors) is basically a derivative of torque X RPM's, the one with more RPM's will have more power, because the RPM number is bigger (like pushing a car at 5 and 10 MPH, it takes the same amount of work at both, but you sweat more at 10 MPH). Lower turn motors are geared down to make up for their "lack" of torque.

Gear two motors of wildly different turns but the same wind the same. The lower-turn motor will be faster, but the higher-turn motor will have more torque.

Hm...think he'll believe a (future) Traxxas engineer?

but also the amount of time you have that number of winds on the armeture help too lie a 15 turn double motor will have less torque than a 15 quad or tripple motor.......the point i here you ask well the less time you have groups of 15 turns the less power your motor comsumes but the result is less torque and raw power like if you racing a touring car you want a double or tripple but if you buggy and truck racing you want tripples or quads for the power out of turns off the line and up jumps....hope that makes sense for you and helps!

um...no...

um...yes...

What?

He (pedelover) thinks that lower-turn motors have more torque overall. Electric motors generally have peak torque at startup, and higher-turn motors will in most cases have more starting torque.

my friend thinks that the more turns a motor has the more torque it has and the less turns it has the more speed it has.

And he is more right than you are, pedelover.

I guess I quoted maxxboy, but was in reality aiming that at pedelover.

REVO-lution, I cannot decode what exactly it was you were trying to say, but, as maxxboy quoted, a higher-wind motor will NOT have more torque than a lower-wind motor.

::cough cough:: You work for RCM RC :cough:

Ok, but really, here's what I suggest you guys do. Take a Look at a dyno shootout for motors of different winds, and you'll see that different wind/turn combinations have different advantages.

One Basic Rule of thumb it comes down to, though, is that the faster your motor(s) turn, the faster you'll drain the batts... Always.

One thing I've noticed about RC is that any tuning option under the sun is a trade-off. More speed for less torque, more runtime for less speed, more of both by spending a pile of money, It's always a choice of what you really want.

Allow me to quote the Signature of an obvious genius.. I'm not sure if Truer Words have ever been said..

• Speed Costs Money, How Fast do you Want to go?

When it all comes down to it, you can have a mod motor hot enough to burn a hole through a vault, but if you don't have the driving experience, then you are doomed to be a lap toy until you log enough practice hours.

That's the end of the sermon, folks.

what i was saying was you have the number of winds and then how many time you have groups of them around the armeture e.g
15x3= a 15 turn triple motor which means it has 3 groups of 15 turns on the armeture. what i am saying is the lower the second number (which can be 2,3 or 4) the less power the motor comsumes and it also develops less torque. whereas if it is highier then the motor comsumes more power and develops more torque...that was what i was trying to say before...also note the motor will run at exactly the same speed be it x2 x3 or x4 its just the raw power to get moving that changes....sorry i made it unclear earlier

Very, Very Close, but I don't think that's a cigar quite yet.

Somebody Call Mis', this thread needs some serious help
