Tekno Neu 2200kv vs Castle Neu 2200kv
 

has anyone out there compared the Tekno Neu to the Castle Neu. i am interested to know if they are comparable. I mean, technically they should be identical in terms of performance but that Castle is pretty badass. and i dont have a Tekno 2200kv to compare it to. can anyone provide some answers on this?

the castle one runs hotter than the tekno neu about 10* the real neu runs cooler than the tekno neu about 10*. power is almost identical

Can you actually provide some data to back up that claim?

skellyo,
what are your thoughts on the Castle vs the TEkno? have you tried them both?

i have all Teknos in my truggies but the Castle is pretty damn impressive. if you turn the shaft with your fingers the Castle is much harder to turn. i am not sure why this is but it makes me wonder if it produces more torque or maybe the Tekno is just smoother?

the real neus will run cooler because of an open endbell, the tekno's are real neus with a closed endbell, and the castle neu is lesser quality only because of automated assembly. My assumption is that any difference is negligible, but until we see a data log comparing the three nobody can definitively say.

I have yet to run my Castle Neu motor that I have sitting here. I also have a regular Neu 1515/1Y in both finned and smooth cans as well. Both the Castle Neu and my other Neus all have about the same cogging torque. I have not had a Tekno Neu, so I really can't comment on it.

Given the great reviews of the Castle Neu, it would be hard to spend the money on a Tekno Neu over the cheaper Castle Neu these days.

That's a legitimate reason for running cooler. However, that goes out the window as soon as you cover the holes like most all of us do.

good point! that's why we need scientific data with all variables removed. I'd go medusa!

I wouldn't say the castle motor is of lesser quality because of automated assembly. Patrick has stated several times that the motors are hand wound. Other machining operations are likely automated, but I am sure the same is true for the real neus and technos. The only difference is where they are made (china vs US).

kinda my point:lol:

Physically the bearings are different:
Castle:5x16x5mm
Tekno:5x13x4mm

Wow, I didn't realize the Castle Neu had such big balls! :mdr:

^LOL @ big balls^

Heck, the castle motor may last longer, with those "balls" LOL.

how can the tekno have a 4mm bearing and a 5mm shaft? gotta be a typo....

if I went neu i'd go castle, but as stated above i'd go medusa

That 4mm is the thickness of the bearing. The 5 x 13 are the I.D. and O.D. of the bearing.

thank you! I wondered how that worked. don't the new neu's also have that larger bearing?

I think so, but I'm not 100% sure.

I have not yet got either a teko or castle neu based, but i have a 1515/2.5D w/ the plastic cover (older neu, no screws on the end) the front end is not covered but with the E-maxx motorplate, I have a hard time getting any heat out of mine. Most times its barely above ambient, this is with 5s/ 51/20 mod-1/ Emaxx tranny w/ a gorilla half tranny conversion and 1/8 buggy diffs in a gorilla revo

Analysis paralysis!
 

the Castle Neus are hand assembled in China whereas the Tekno Neus are hand assembled in the states. Both are great motors. here are the motors i have owned and my experience.

1512 1.5D/F Neu
1515 1.5D/F Tekno Neu
1515 1.5D/Q Tekno Neu (Q means sqaure canned)
1515 1y Castle Neu (just got today)

In my experience the Tekno Neus have been better than my regular Neu. Just seemed more smooth, faster, etc.
So here is what led to my questions;

I like a really fast setup so i run my 1515 1.5D's on 5s. My temps stay below 150 and it has seemed like a all around great setup. Then my friend comes over with his new Castle Neu and it is just as fast as mine. I was surprised! I thought with 2200kv it would be slower. So then i wonder, is the Castle Neu a better motor or is 2200kv just more than enough power to get the speeds i like and the 2700kv isnt adding much? So i start thinking if i can get the same speeds and power with the 2200kv and have lower temps then why not. So i am thinking that the speeds have nothing to do with the Castle motor as much as the fact that 2200kv is plenty for what i want.

So now i am in the process of listing my 3 Neus on ebay to downgrade to the 2200kv motor. i would just keep the Castle Neu but i really like the square canned Teknos more than anything. that said, i like how castle has made their motor leads longer so there is no need for extra connectors/resistance and you can just plug straight to the ESC.

My wish for the perfect motor is a square canned Tekno Neu with motor leads like the Castle both in length and how they are completely sealed off. The tekno design is an improvement over regular Neus but castle made it better still. the tekno design can still let dust in. like they say, "if you can build a better mouse trap, people will buy." its kind of a trade off for me. either i sacrifice the square can that i want or i sacrifice the motor leads that i like. why cant i just build my own damn motor????!!:lol:

Is that post title a shot at me?:lol:

i was referring to myself actually...but if the shoe fits....:whistle:

maybe when it comes out you'd like the Flux Tork....I think it has what you want. It looks like it mounts like a square can motor, its a 2200kv, its made by castle so i'm sure the inner parts are the same, and it probably has clean wires coming out the back.

at first i thought you were f'ing with me...like my tastes were so complex i might as well build a flux capacitor...until i googled it. so its basically a MMM combo re-labeled for HPI it looks like. the motor isnt quite a square can but who knows, the real things are always different than the prototypes. maybe hpi/castle will make a sqaure can just to have one more thing to try to beat out their competition with.

here is what the site said about the motor case.. "The Tork 2200 is mounted to the 3mm 7075 aluminum motor plate with two 8mm billet machined aluminum clamps so it won't move or shift under the immense amount of torque of the brushless motor."

so the two parts that resemble Tekno's square can are actually clamps. kinda like these i found earlier for smooth canned Neus. simple yet efficient.

btw Hoov, whats with the "bottom line"? is that a Nazi camp or an old man's wet dream? lol

so get this....the reason i wanted to go down to the 2200kv is recently at the track after 20 minutes of racing my motor temps are like 155* to 160* which is higher than i like to be. i couldnt figure it out. all summer my temps were like 130 or less. so this is when i took notice of the 2200kv motor thinking it would bring my motor temps down. but then i read something in another forum that answered my question for me. that a center diff motor mount will result in motor temps about 10* hotter than a Tekno chassis motor mount. the reason being is the alum motor plates and alum chassis all help to dissipate heat away from the motor. this was tested by someone. makes sense.

in the summer i was running the TEkno chassis mount. now i have a RCM conversion and not only do i have the RCM center diff mount but i had to make a carbon extension piece so that i could fit mech brakes. so the carbon piece covers one whole end of the motor can. so all of this is resulting in hotter temps. so i think it is finally time. i have a Tekno chassis for the RC8. the first real-world, hard-anodized RC8 Tekno conversion for the public.:na: so its time to make the switch. what can i say? i am just a Tekno guy. I must say, i really like the shape of the RCM chassis and how the components are laid out but overall i have had to do so many mods to try to make this thing work like i want it to. nothing wrong with the kit, just my preferences. tekno's kits are already built to my tastes so no mods required. :party:

anyway, i am still tempted to get a couple of Tekno 1515 1y/Q's but i am gonna wait a bit. maybe Tekno will counter the new line from Castle with a square canned-long wire-sealed endbell-motor that some of us anal-retentive bastards would love to see.

When the RCM site got an update a few days ago, the line that seperates the signature had disappeared....so ppl started drawing in their own...I wanted something different, so I found a pic i liked and used it as my "line"...

...but now that you mention it...it does kinda look like something out of schindler's list :neutral:

That's the reason why I used the stock Emaxx motor mount instead of the gorillamaxx single mount on my gmaxx. The extra surface provides a good surface for heat to dissipate.

I didn't know they made them sqaure. Thats pretty cool so you really dont need the motor mount. Looks like you can still mount it up to one though if you wanted.

the square canned motors are the absolute best and my favorite and i have tried them all. stock Neu, Castle neu, round Tekno neu and square Tekno neu. half of them are on ebay right now in fact. but i love the square one. mounts right up to the chassis if you wanted but its best to mount them on the motor plates for setting gear mesh. but no mount is needed. also, you can strap a fan right on with no extras or mods. so this setup is super light and very efficient. and they look cool too. the reason i am selling my other Neus is so i can buy all square ones.

This is a neat discussion and I think it all comes down to what the end user is willing to trade in return for desired performance.

I have a Neu 1515 2.5d, a Tekno Neu 1515 2d, and a Medussa 36-60-1600.

They all seem very stout on 6s and will only run hot if I decide to use gearing that's way too high. I'm sure we all know that the Neu's 15xx series are a bit larger (more torque as well) than the Medussa 36-60-xx series motors. This extra "umph" gives more range for gearing selection before the motor runs too hot.

I use the 1515 2.5d in my heaviest car (Muggy), 15152d in my converted Revo, and the 36-60-1600 in my Hyper 8. After fooling around with MMM esc and radio throttle curve settings to my liking, takeoff's are brisk without being too violent on drivetrain parts. Even when bashing in wide open spaces, I've found that gearing them too high only results in speeds that are near un-controllable and a motor that heats up quickly.

So.. I although I haven't tried a Castle Motor yet, from what I'm reading it sounds like it falls along the lines of the motors I have now. In a proper set-up, I think all would do just fine and run cool.

Since I don't have any heat issues with 6s 5000mah packs, I don't have to mount my Tekno Neu to the chassis and risk pinion/spurr misalignment due to chassis flex. I use Mike's mounts instead and call it a day.

Higher voltage, lower kv-rated motors will draw less current for the same power output.
If I were to custom order a set-up, I'd go with something along the lines of 10s or even 12s with a 1000kv motor. Yes, the batteries would cost more but hopefully those expenses will decrease the more battery technology increases. Imagine being able to run a 45-minute main without changing batts and having no heat issues.

Well, I don't have a Tekno Neu, but I just received my Castle Neu and wow I'm impressed! :D Running the same 4s2p A123 packs in my ST-RR with 15/50 gearing, the CC Neu doesn't even get above ambient temp.

In comparison to my 2084kv Feigao 8XL which was getting up to 60 degrees Celcius in about 2 minutes at this setup.

I expected the CC Neu to be better, but this was really unexpected :D

the 2200kv is a 90% efficient motor. that means energy produces power, not heat. they are great motors. other, less efficient, motors waste more energy on heat that never turns into power. Neus are just the best that money can buy it seems.

Tekno Neu is great for Tekno conv. kits(certainly it should), but not as "universal" as standard sized motors like Medusa or CastleNeu.

The regular Tekno Neus are the same size as a standard finned Neu. The Q can Neus are the ones that are better off in a Tekno kit. I've seen people use the Q can motors in an E-Revo before and it fit, but it's harder to make it fit.

SO BOTTOM LINE HERE...is the castle Neu as good as the Neu

i think so. at first the one thing i like better about the castle design is the long motor leads so i dont have to solder extra bullets to reach my esc. but then if found out those motor leads arent actually the copper wind wire. it is just 10awg wire soldered to the motor leads inside the can. so its not much different than a Neu or Tekno neu where you have to solder bullets, other than it saves you a little time. but i have tested the castle motor and seems very good. it stayed extremely cool. never broke like 90*. it seems like they have been selling like crazy. i would bet that 80% of current Neu motor purchases for conversions are going to the Castle motors. they are cheaper for the essentially the same thing.

there is one thing i noticed on my castle though that i didnt think was a good thing; i could move the shaft in and out about 2mm. so it hadnt been properly shimmed and the rotor was able to move back and forth inside the can. i tried this on all my other tekno neus and they did not even move a fraction of a hair. so i dont know how detrimental that could be but i thought that was something that should not be there.

as for the square cans i was able to mount mine to my RCM RC8t conversion with the center diff motor mount no problem but they are more ideally mounted to the tekno style chassis mount.

I have 1 of each of these motors.The Tekno Neu is certainly smoother but the CC Neu is a monster on 4s geared with a 17t pinion in my SC8.Unfortunatly there is alot of snow and ice here so tempng anything is pointless.The CC Neu motor seems alot like the original Neu 1515/1y/f with the tighter magnets.

i just spoke to the guys at Tekno about that exact thing cuz i noticed the Castle motor shaft is really hard to turn with your fingers whereas the TEkno Neu is super easy. the said that there motors are newer versions the neu created because the older versions like Castles create more cogging. whether it creates more torque or not i am not sure but they smoother setup wont cog nearly as much. i imagine the next run of Castles Neu motors will be the smoother one too as it sounds like Neu has made this change on all motors they produce.

i noticed this when i tested my CAstle motor in fact. i couldnt figure out why it was cogging cuz once i had set my esc to medium start power my tekno motor never cogged. it wasnt that bad with the Castle but i couldnt run at low speeds like i could with my tekno.

Yea, I actually thought I'd broken mine because it was so hard to turn by hand. Made setting the mesh kinda interesting too lol.

I haven't noticed any cogging while its running tho.
