I don't know if we've run the numbers on these yet, but I'm guessing they are ~400-450 watts continuous, and ~800-900 watts surge. Looking at the specs on a Neu 1509, it is rated at 500 continuous and 1000 surge. So I doubt a shorter and smaller diameter motor can handle more power. Pat may have some data to back this up, as I am just assuming based on the 1509 specs.

Just claim 110% efficiency and 1000w looks pretty reasonable to me.

When can we buy these?I have a Slash that would love one of these.

Plenty o power! Thanks for the info. The 750 I got was just a max surge for the run. Close to enough to a 1509 With better wires and a castle price! I would say that in order to reach 110% efficiency they would need some flames on the can though....

When you guys say "~400-450 watts continuous", what does that mean?

a) You can run them with enough load so that they are putting out 400-450 watts for "X" minutes [fill in "X"]

b) You can run them with enough load so that they are putting out 400-450 watts until you dump the typical 5000-6000 mAHr 2S LiPo battery that fits in a 1/10th scale RC car at which point the motor is almost toasted

c) If you had a 6 ounce miniature nuclear reactor that fit in an RC car and put out 8.4V at 65 amps and would run 2 years between refueling, you could run it at the max load of the reactor (figuring 85% efficiency on the motor), stopping only to lubricate the bearings if/when needed, until the reactor needed refueling 2 years from the date you started the test (anyone remember the IB Infineon PDF sheet (joke) from a few years ago?)

d) [you fill in this alternative]

I'm just trying to get a feel for how long "continuous" is supposed to mean and under what conditions of temperature and cooling/heat sinking.

Also, how long can it run at the "surge" rating?

Well since I am not a sponsored driver , when can we buy them and how much $ unless I can get sponsored LOL.

[slash_48]

On the nue web site the 1509 is rated at 750 watts continues and the 1506 is rated at 500 continues both surge double that. Are these motors based of the nue 1400 series?

My opinion is that we can't speak of continuous or surge watts for driving application... The setup you are driving requires a certain amount of power, and this amount fluctuates a lot.
For example if you put a 1509 in a 8 scale buggy it will consumme (approximately) the same watts than a 1520 in the same vehicle (geared for the same speed).
The watts given by NEU specs are IMO for air or boat application, where the current are pretty continuous and constantly heavy...
All this to say that, only the temperature of your motor (and not a number of watts written on the motor) defines its limits, if your motor get too hot and risk heat damage, that's mean you are pushing it to hard... Same thing for the ESC ^^

While slotless motors rev faster, have less inductance (so respond faster) 4 pole motors have much more torque -- and with some of the software changes we've made to run the big 4 pole motors well (like the 1515) the differences between the motor designs have become smaller.

Note that I was talking about "light" 1/10th scale vehicles in that post -- but the trend recently have been to heavier, more robust 1/10th scale cars.

Also -- please note that we haven't discontinued the CM36 motors -- they will still be available. So, what we recommend is that for lightweight 1/10th scale vehicles where maximum acceleration is the most important aspect, the CM36 slotless motors are still best. For heavier cars, the 1406 four pole motors will be superior.

Thanks!

My motivation is efficiency, i know with some new products, they are making them more durable with thicker or denser materials. But i'm after efficiency, I love my stadium trucks, light, agile and very quick. Any motor will make them fast, even Novak, But i want cooler running and longer runtimes. If the 1406/4600 can pull a Slash 4x4 without problems, the 1410/3800 can pull my T4 all day without any trouble. With the 1406/4600 being as strong as it is, I believe the 1415/2400 might be a good 1/8 buggy/ 1/10 truggy motor on 3s. lipo


Hey Patrick, Will there be some smaller motors for the mini classes?

I understand that. I know from testing that I average 14 amps during a race running my Neu 1512 on 4S in my 1/8th scale buggy, for an average power consumption of 210 watts (far less than even the continuous rating of the Neu, let alone the peak). That's why the motor never gets over 130F.

I'm trying to find out what Castle means by a 400 watt rating. It is obviously not as simple as an average watts over 10 or 20 minutes, or that would say I could use a 1406 to power my 1/8th scale buggy which only uses 210 watts. I think we are all pretty sure that is not a reasonable scenario.

[slash_48]

I was just pointing out that the nue 1509 is rated at 750 watts not 500 like the 1506 is. I think it is great to see castle building better motors for the 1/10 scale cars. Have not been happy with any of the 2 pole 1/10 scale motors thats why I run the medusa 3650 in all my 1/10 scale cars.

The answer is b, but with less motor heat... At the end of a 5000mah run, the motor should be at about 80C. Well within reasonable heat limits. Usually with a good setup, you should be able to run about 10000mah without putting the motor in any jeopardy...

Castle sent me a 1406-7700Kv to test Monday and decided to house it in my TF Funny Car. Was going to and test it this weekend, but work and rain kept me from following through. So the next chance I get will be at the Lonestar Nationals at Autorama 2010 in Houston. Will report to Patrick right after.



The best ET so far on this Funny Car has been 1.46 with 2-pole motors and I expect to see a lot of improvements there with the 1406-7700.

In case you're wondering, those are 8mm bullets on the ESC So far, they've helped me get a 1.320 pass in my TF Dragster.

:O

what batteries are you using to power that beast!!
