Castle motors Watts?

[DISAR]

Does anybody know the watts for these Castle motors 1515, 1518, 1520, 1717?

I have the 1515 and it is slightly bigger than the Neu 1515, hence it can handle more watts I believe. But what are the limits for these motors?

[Rumdog]

Not sure, but i have the 1515 and 1518, and they both RIP!! I run the 1518 on 5s2p in a Rico 31 mono with a x548 and It has Tons of power and comes in nice and cool. Gonna swap it out into a DF 33 soon and see what she can do. These are the only specs I know of...http://www.castlecreations.com/products/neu-castle_motors.html

What kind of speeds do you think you are getting with the 1518 on 5s?

[DISAR]

Looking at the dimensions of the 1518 it is almost the same size with Neu 1521. Same watts?

[Rumdog]

getting 58 mph with crappy 20c cells. Have some new 30c on the way, and gonna run a pitchier prop. I'm guessing watts are close to the 1521.

I personaly dont think thats true. Castle is implying on their home page that their Castle-Neu motors are approx. 85% eff. when compared to cheap chi 2 pole motors. And the Castle-Neu motors are made in China, not the USA. They are advertised with sintered rotor magnets. There is nothing in the advertising stating individual continous wattage ratings. Thats why I have my doubts about putting them on parr with Neu's and I bet I am right that they dont exceed Neu ratings even if the can is larger.

That's why I am asking here to see if someone has any experience with these motors comparing to Neu. The difference in price is about 50-70$ but do they have same power?

58 mph is very good! with a cool motor.

[Brushless55]

I know alot of guys love the 1515 motor in their ERevos
but I don't think they have the exact same power as the NEU motors

[Rumdog]

I personally don't see how they'd be different power wise.

[m4a1usr]

I personally don't see how they'd be different power wise.

Differences could be quality of magnets, iron and of course efficiency. All contribute to how much electrical energy is used effectively and not wasted to heat. Its probably not much, but I have not done any emperical testing to know for sure. Might be little, might be none, might be ?

i have a 1717 that i am putting in the df 35 hull...far from completing it though..i will post the results once its done for some more comparison info

[Fluid]

I personally don't see how they'd be different power wise.
Okay, let's see.....
- tightness of winds
- quantity of wire on stator
- quality/gauge of wire on stator
- quality of magnets
- length of magnets on stator
- temperature limit of magnets
- quality of bearings
- air gap between armature and stator
- quality of armature laminations
- thickness of armature laminations
- straightness of armature shaft
- quality of assembly/endplay

It's easy not to see the differences if you don't want to look very hard......

[Rumdog]

Aren't they supposed to be the same motors, but assembled in China? That is what I meant by my comment, Not that I don't understand what makes a motor good or bad. Have YOU seen the differences?

[DISAR]

For sure there will be some manufacturing differences but at the end of the day what matters is performance, speed, temperatures and endurance.

But why Castle don't make public the watts of these motors? Probably some kind of deal between Neu and Castle, who knows.
What I do know is that from my testing a Castle 1515 is better than a Feigao 580. I haven't compared yet with a Neu1515 yet though.

[Brushless55]

IMO, if you want the edge get the NEU motor

[graill]

Personally i would ask the manufacturer/distributor of the motors for all specs. White papers should be available on everything, especially high grade electronics/motors.

If manufacturers/distributor remain silent, draw your own conclusions from that. I know i would. :smile:

[hydromaddicted]

found this

Castle Neu
-Casing closed
-Kevlar wrapped magnets Not carbon inside as the "real" Neu
-Wires comes out on the side, not in the back
-The motor shaft has a flat spot
-5x16x5mm Bearings Japan (Koyo or NMB - CNC grade, 100K RPM rated)
-Laminations M19 non-oriented magnetic steel Japan
-Magnets Same as Neu – China N38UH magnet

One reason, the problem with posting "real" numbers, other companies will lie to say they have a higher number. This way the results speak for themselves.

NEU motors are built better and their performance is better
run cooler, less wasted amps, and more power

[DISAR]

I agree with that and that's what we need to know from personal experience.

[Brushless55]

And I will throw this out there..
If anyone wants to send me a Castle motor and NEU motor of the same size, to do some runs back to back in my MM or big gas KOS I will! :hug1:

[longballlumber]

Has any one actually called Castle to ask?

[sailr]

In my opinion, watts are too subjective to be truly measurable. Most brushless outrunner airplane motors just take the max volts the motor will stand by the max amps it will stand, multiply the two and give you watts. Absolutely meaningless. Watts change with battery, prop, etc. In the airplane world, I measure the thrust which is a much truer indication of how the airplane will fly. Then I use a watt meter to make sure I'm not gonna burn up the motor with that prop. With boats, it's much more difficult. Other than an eagle tree system, you can't really know how many amps it is pulling and the prop is often in and out of the water with serious amp spikes going on. I pay attention to not exceed the max amp and max volt ratings for the motor and then check the temps. Works good for me. Too many people want to run 4S on a motor and esc only rated for 3S and then wonder why stuff burns up! Go figure, eh?

[Rumdog]

All that I know is that mine work excellent, with very little heat.

[sailr]

Yep, and that's all you or anyone should be worried about.

Ryan,
Did you get the pics and tracking number?

I've seen a few threads through the web on just this topic, and the NEU motors are better than the Castle motors..
Castle motors are great, but the better of the two is NEU, they are much more efficient :Peace_Sign:

[Rumdog]

How have people drawn this conclusion? Since my Castle's run very cool, that means they are losing very little power through heat. I'm tempted to get a 1515 neu to compare to my castle/neu.

[ozzie-crawl]

seems to be a lot of "neu,s are better" but haven't seen any evidence to back that up, and if there was i doubt there would be enough in it to see a difference in most setups
:hornets_nest::hide::hide:

[Rumdog]

I agree. I also think that if they weren't up to par that Steve Neu wouldn't be afilliating himself with the motors.

[m4a1usr]

Nothing can be done about motor efficiency. Thats relatively speaking, a fixed number. Now given the fact you are running cool in your setup says your running great in all the important areas. Thats the best anyone can hope for. Even if you were running a cheap chi motor like a Keda/Pulso and it does what you want it to do. Where is the complaint? There is none no matter what you would compare it to.

Since Castle motors is the topic and equivalency is the question its doubtful anyone can offer serious advice unless they have done an even basis comparison. I certainly cannot. The Castle-Neu's have already proven themselves in many applications. And I hope this discussion has some input from a member who indeed has done a side by side comparision. All my comments are based upon opinion and from experience. Nothing more then my 2 cents.

[RIPFENCE]

on the castle sight it says that they are 85% efficient...the neu's have tested at 91% efficiency rating...how much difference might this make? you could argue that the neu may have some better runtimes...i am not sure if you can argue about the heat buildup because the castle has heat sink fins on the case and may just disperse heat better any way...its a tough one..i have a 1717 and a 1521 1y and a 1527 1.5y...i have not done any real testing yet but i am sure i am not going to be disappointed with any of them! it would be nice to know that if you choose to go with a castle that you will get similar performance for less cash

:hornets_nest::hide::hide:

Google it..
the reports are out there..
nothing wrong with Castle, not sure why some go down that road..
NEU are good Castle is not, not one person has said this, but some want to go down that road and I'm not sure why..
Castle motors Rock! :rockon2:
NEUs are just a bit better :Peace_Sign:

That does mean more overall power not just more runtime..
but cost vs performance they could actually come out the same, if that makes sence.. :Peace_Sign:
as for me, I would save the cash and go Castle...

[hydromaddicted]

I asked Neu this? What are the actual differences in the 1515 1y Neu and the 1515 1y Castle/Neu motors?Seems the Castle is slightly larger than the regular Neu is there any difference in output/watts?

I got this reply

The Castle motors were designed for use in trucks and buggies with features to suit those applications. Our motors were designed around flying so they are lighter. We also offer a much wider choice of Kv. The design of critical parts of the Castle motors is covered by a license agreement.

[RIPFENCE]

we need one of the master gurus here to construct a test and shut us all up..maybe mythbusters can do it...i suppose if you are happy with your motor whether it being castle or neu then thats all that matters anyway..i would think you really could not go wrong with castle series if just sport running for fun and not serious racing

[ozzie-crawl]

as they say there designed for different applications, one may work better in a certain area than they other and vice verse.
i have seen both in cars and there both have stupid amounts of power, combined with lipos run times are what we only dreamed of a few years back.

[Himalaya]

roughly:
1515: 1300W
1518: 1550W
1520: 1700W
1717: 1900W

[DISAR]

I don't think so. These values are low. I tested the feigao 580 with the cc1515 and with the cc1515 I got more speed and less heat. The 580 is stated for max. 1800-2000 watts so the 1515 is for max.2500 watts I believe or more

[Himalaya]

Kinda making sense. but please be aware the "real" Neu 1515 is rated 1250W ONLY. the CastleNeu is slightly bigger.

The BLACK Neu does have another power rating: 2500W for 30 seconds BURST. So you are right, many manufacturers out there play this numeric game with INTENDEDLY forget mentioning CONTINUOUS VS BURST ratings.


OTOH, a direct comparasion between Feigao580 and Castle1515 looks in need of more discussion. They have diff size, diff weight, diff # of rotor poles, diff # of stator slots, diff KV value, diff RPM rating, diff temp grade magnets ....... the 4-pole Neu naturally have more torque than the 2-pole Feigao, the steel cored 12 slotted stator does run more efficiently at low RPMs.....

[Andrewg]

Dont worry the Neus are better, much better - because Steve Neu designed them. But check the weight, the idle amps, the actual temps, the records in almost every RC discipline to se the difference.

The Castles have an excellent design and execution but the materials are a different thing and that counts. Like comparing a billet race engine and the cast production version. Both are very good.

[Rumdog]

the neu design is carried over to the castle motors, hence the name. Rc boating is the most strenuous on any rc component, i want a comparison here that shows advantage/disadvantage.

[m4a1usr]

Good to see you over here on OSE Andrew. In case no one recognizes his name Andrew is probably one the "gurus" on Neu motors. As far back as I can remember he has been the voice of knowledge/application of Neu motors in boats. Not to mention his other endevours. :thumbup1:

John

[Brushless55]

Either way, NEU motors rock..

[Andrewg]

John hi, and thanks
