View Full Version : Has anyone tried an outrunner in a car?
It seems that airplanes have mostly moved over to out runner motos. I was wondering if anyone had ever fitted one to a car before and if they did how it went.
i tried a cyclon 5000 motor by electronicmodel, in a xray and 7.2v 3600 battery.
i was very impressed with acceleration, spinning wheels even at high speed. so what i can say is a motor with very high torque, more usefull in a 4wd buggy i think.
a problem could be the hi revs of the outern rotor, it can be scratched easily.
this is my limited experience. (and excuseme for my english!)
now i have a mamba max 5700 and it seems to me that it has more rpms and a little less torque

Pardon me.
What is an "outrunner" ?

Here's the link to cyclon car motors http://www.cyclonbrushless.com/cyclon-intro.html.

I ran a big Himax outrunner on 6S in my Ofna buggy, it was a monster. Tons of torque, like drive shaft snapping torque. It was mad. Not a very high kv motor, but the torque, and throttle control was much better than the inrunner i had been using.

Ok so it is a Brushless motor.
Why is it called an 'OutRunner' ?

The standard motors we use are called "inrunners." They have the magnet inside of the wires. An outrunner is the opposite, with a magnet rotating around the wires.

So an Mamba max motor is an inrunner?? :huh:
Does anyone have a diagram, or drawing??? just so I can understand better :confused:

So, does the can spin? How is that attached to a car? Or is there some sort of middle layer between the wires and can which spins somehow?

Check out the link buggy man posted to get an idea of what they look like. It's basically a can within a can sorta (that's the easiest way for me to explain it) with the windings on the inside of the magnet can piece thing, which then probably is attached to the motor shaft somehow, and there's the outermost can, which allows the "inner can" to spin. It's a lame explanation, but that's the best I can do... :teacher: :p

And by the way
But sometime's you get what you need :wave:

That explains things WAY better than how I did.

Thank you very much
Now I understand :D

How did the cyclone compare for size and weight with the mamba motor? From what I have been told outrunner can be much more efficient. Do you think a 2000kv outrunner would match a 3000kv inrunner if you geared it up?
I'm kinda thinking out loud here :)

I was kind of thinking the samething.

Now that I think about it (out loud...as everyone else is...:D), one of them cyclon motors would be sweet in my T3... Nice light motor, probably PLENTY of torque...decent Kvs. Hmmmmmmmmmmmmm. :driving:

Normally a 10 pole LRK (wich is the short for outrunners in europe) is able to pull out roughly 5 times the torque than a 2 pole inrunner design.
so a 14 pole motor will even pull out 7 times the power.
take in mind when using it (or trying to find a good winding) that the rpm has to be 1/5 or 1/7 or the normally used inrunner.
I used them in my Emaxx (full first tranny could be left then) and as a motor in my 8th buggy prototypes too, the full center driveline was left then, the motor has had enough power to connect it directly to the F/R gear box.
These Motors have to be protected by a small housing from the elements, that is mostly the worst part.
The accleration won´t be that fast and agressive than with a good suited 2 pole inrunner, but the cogging simply isn´t there !!
The LRK´s also require a setup with more than 25 Degrees timing, not all esc´s offer these functions !!
As you might roughly see it is a very special way to power cars with LRK Motors, there are some special solutions needed, especially in bigger cars like 1:6 ones (the LRK´s are a WAY good for these bigger scales ;-) )
