Awesome! How has it been holding up so far? Any comparisons against the real Neu's?

Nice to see that the rotor is balanced, and appears to have some sort of wrap on the magnets. The internal wiring is difficult to see, but does kinda look machine wound... Hope I am wrong.

Runs great, a little hot- but thats probably because its geared up.

Perfectly no problems so far

Is there any real way to tell the difference?

Thanx for sharing. Is the rotor spinning freely on the Castle Neu when you spin it with your fingers? Beeing able to disassemble the motor with screws is a big plus. The protection ring in front of the windings is a good idea for those of us trying to use screws with too much length.

And for those of you who want to compare the Castle motor with a Neu 1515 and Neu 1512 here are some pics while i dissassembled them.

The Neu rotor uses carbon rovings and the front of the motor is part of the can.




The backplate is only glued but the actual Neus do use screws too. Bigger Bearings on the Neu 1515.




No protection ring in front of the windings.

The motor is very hard to turn over by hand. i have checked everything and there is no binding on the rotor. just strong magnets.

i beleieve the bearings are something like 5x13 or 5x14, look like they should be wheel bearings

Both endbells are removable, and yes the little plastic ring is a lifesaver


I have the 1515 1y. great motor, beats the crap out of my 8xl...(to be expected) but wow soo much power. after 40 minutes of running geared for about 50mph the motor was at 152, but only because i had it geared up (freind lost my 13t pinion)

Thing is a torque monster..

I wonder what Patrick will say now after he said the rotor wouldn't be wrapped in Kevlar? Maybe he saw the pictures of my 6 pole with the shattered magnets and a little light clicked on and he said it's needed now. I hope to see other Kv options soon.

As traxxas promotes the Castle ESC/motor for up to 6s with a 2200kv motor which will rev this baby up to 50000rpm i guess somekind of wrapping is mandatory ;-)

Looks like I'll be canceling my medusa order for my E-Revo. I was getting tired of waiting for the caslte motor, but now it's release isn't far away.

I'll still be getting a medusa for my rusty though.


Ben, whats the lenght/diameter of the motor in mm?


I will spank a nitro any day...guaranteed. :)

That's what I and a few others told Patrick. He did say it wasn't needed, but I like the fact that he decided to do it.

They actually say 6s on the 1512 1Y 2650kv! or 58830 RPM - I got as far as 5s (50k rpm) and temps were ok....

This was how it went Lutach,

When we started doing destructive testing, we found that the rotors that were wrapped handled higher temperature than those that were unwrapped -- even though there was no difference at low temp. Turns out that the glue is stronger than the magnet material at lower temps, but at higher temps the glue gets a little soft, and the wrap helps keep the magnets in place.

Also, we found that a wrapped rotor usually didn't destroy the stator when it failed (the wrap helped cushion the blow to the stator) where the unwrapped rotor usually did destroy the stator (and pieces of magnet got EVERYWHERE in the stator.)

Oh, and BTW,

This is a hand wound stator. This type of stator design isn't practical to machine wind.

It's a good thing to have anything with more then 2 pole wrapped with some kind of reinforcing material. When will you have other Kv motors available? Is the shaft on your motors epoxied to the rotor assembly? I have suggested to a few other motor manufacturers that before the magnets are place, they should use set screws to hole that assembly to the shaft to avoid any type of problems where the shaft comes loose. Many of my Aveox had this happen and one was just recent.

Regards,

Luciano.

Nice pictire and info, the CC motor is a real looker and built well it seems. Now I dunno what motor to buy - that one, or a 70 or 80 mm Medusa. Curse you all....
