I think he means actually having the fins of the motor machined out into a spiral to form water channels. Then having a cover to mate that and seal it all up with water in/out puts attached to it. That would probably take some $$$ in machining the inside of the outer cover to match up.

What he probably meant was a motor designed like the one in the attached picture.

That is a cooling coil, not a cooling jacket. They work, but not as well as a jacket does.

is that a hacker c50 comp?

Yes.

thats a bad *** motor!

Yes, but 4 and 6 pole motors are taking over and for a good reason.

Are the combos going to come with the black motor like the pic or green like the rest of castles motors. I like the black!

I think the ones made for Traxxas will be black and the Castle ones will be green.

could be, i personally like the black.. green doesnt go well with very much LOL

I´ll really like to see a motor can with heat pipes. Even if they are heavier than a simple heatsink, at least the are pasive devices.

You shouldn't need heatpipes, water cooling, or even fans though. If your motor is running too hot there are issues in your setup. It could be gearing, binding, poor quality motor, etc. but a proper setup will not overheat. Before the unfortunate frying of my Neu, the hottest I could get it was 145F which is fine considering how long I ran it, how hard I ran it, and it was too high of KV for my application.

i got mine to 155 but was geared for 53mph or so.. :intello:

not if you are running high voltage! 2poles can take high voltage better than 4poles. Now 4 poles are better for 6s and under 2poles are going to have higher rpm

rpms causes destruction.. 4 and 6 pole motors make more torque and turn lower rpm. keeping them in below failure point, the added torque allows you to gear to compensate...

He is right multipole motors are better..at high voltage

Traxxas motors are all black, Castle are black and green.

nice! but i already have a 1515 1y so will the ccneu be better or about the same:neutral:

not if your motor is rated for it! the c50 comp is a 80000 rpm motor. and the 9xl can take up to 8s (my future bl plans)

I don't know how you can say this. And I have to disagree with you on this as well.

Usually, pole count is determined by rotor diameter, not by voltage. Voltage doesn't really enter into the equations at all -- you can always change windings to make up for pole count difference (for example, a 2 turn 2 pole is the same torque as a 1 turn 4 pole...)

I also think the 4 pole mentioned by Patrick will still have more torque being it has twice the magnet. Basically a 2 pole would be a 4 cylinder and a 4 pole would be 6 cylinder and 8 pole well would be 8 cylinder. Ever wonder why outrunners have more torque then our popular 4 pole inrunners?

kt and kv are inversely proportional, so when kv decreases kt increases.

We need sensored outrunners! I want CC to make a killer brushless crawler setup with a sensored outrunner and an matching esc with a built in switching bec that can handle 4s lipo. Had to throw that in, since it seems like Patrick is watching...:intello:

CC won't build a sensored ESC or motor though, Patrick has said that a few times. It would make for an awesome crawler, but someone else will have to do it :neutral:

I think Holmes Hobbies is preparing sensored outrunner for sale right now.

yes, his qoute was something to effect of
"we wont build a sensored motor because they are based on an inferior design" IIRC

I spoke with a few companies that might make me some 4 or 6 pole inrunners with sensors. Only time will tell though.

Yes, but a 4 or 6 pole motor will have a higher Kt than a similar 2 pole with the same Kv.

IIRC Patrick then said he was actually building a sensored controller as the market still wanted one... :diablo:

is there anyway to add a sensor kit to a motor??? i know its odd but imagine hollow spacer on the front of a motor, and an optical or some other type of sensor inside.. a sleve or magnetic ring on the motor shaft.. would definately be cool

arnt they black and brushed aluminum(or some kind of metal)

Wasn't this to be part of the MM Pro?

That's what I remember. I think he said he they were going to include a sensor port mainly for rock crawling on any sensored outrunners that might be released, just to help highly loaded startups.

well now i need a new speed control as mine just shot two foot flames out...

Did someone say outrunner? LOL

I for one can testify to the torque of the outrunner. In the experimental direct drive setups that I have built, a 12 pole outrunner with a low (600kv to 1000kv) has enough torque to shatter diffs and even bearings. I'm talking acceleration, not shock from jumping. They can also easily pull gearing that 2 pole motors will smoke over.

When considering torque, think about how many rotational degrees each phase shift is required to turn the armature, often times with close to the same amount of magnetic strength as a 2 pole.

Armature Diameter has a huge impact on torque. It's just a matter of leverage or distance from the magnetic force to the rotational center.

So Can I buy the Black CC NEU? Or is it going to be a combo only with the BL e revo?

I dont like the green motor, the black looks alot better IMO.

I feel you pain, my old Turnigy 50-55B Would eat up diffs for lunch.

I would still like to see an addon, with adapter with a sensor pack. would definately be cool

Anyone?

Do we need a new thread?

no need for a new thread.....look at post # 56

That doesnt help

I want to know how there going to be sold. I want the black motor, not the green one. So is castle making 2 kits by them, or the green castle kit from them, and have traxxas sell the black ones. Or is the motor going to be avalible only by buying the BL e revo?

Or?

I would say that if you want a Black motor, you'll have to wait for people to part them out on eBay and pick one up there. I am betting that you will find BL E-Revos parted out all over eBay once they come out so it'll just be a matter of time before you win a bidding battle for one. Expect to pay a heavy price to get one within the first month or two.
