Tekno Neu 2200kv vs Castle Neu 2200kv

[Ryu James]

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.
