Yeah, that's pretty much what we came up with -- but we don't sell much at all direct. Less than 10%.

They won't affect reliability -- it would be very hard to improve the reliability by much.

The new rotors improve cogging torque and efficiency a little.

Ok, thx for the input, and for that :

This means that Castle will sell some 1524-1527/1Y or some 1518-1520/1.5Y motors ? That would be "cool" :lol:

Maybe!

Can you give me a good application??

Thanx!

Yes I can try.

1515/1.5Y 1500kv : more inductance so more controllability than the higher Kv 1515/1Y (perfect for 1:8 racing buggies 5-6S).
1518/1.5Y 1200Kv: same for 1:8 racing truggies
1520/1.5Y ~1050Kv : same for 1:8 racing truggies
1524/1.5Y or 1Y : 6x6x6 Monster Trucks or heavy crawler :lol:

1717/1.5Y ~1050Kv : XXXXL Monster trucks on 6S ?

^On that note;-

If you could manage an 1800kv and 1600kv motor in a 1515 can, then there would be ALOT of guys who would snap them up for their traxxas MTs; the 1518s were a hugely popular upgrade to the regular 1515 1Y motor in the brushless emaxx and erevo. The trouble with the erevo however is that the 1518 motor is just a bit too long to fit, so guys have to trim the rear shock tower for clearance; 1800kv in a 1515 can would be brilliant, assuming you could get the same kind of efficiency as the 1518 motor.

I think thats the only niggle with the NeuCastle motors at present- if you want a lower kv rating you have to go to a longer motor- having different kv ratings in the same can size would be a real hit, Im certain of it. Heck, you might even persuade traxxas and hpi to get onboard and offer different versions of the motor with their BL trucks, take advantage of the guys who are sold on the lower kv & higher voltage way of thinking :yes:

I also do not understand why no 1515/1.5Y from Castle.
This would be the perfect motor for MT's and Truggy's.
I always thought it would come out soon due to under the Neu chart (on Castle's site) it is recommended for a Truggy.
I'd say this would be a real good seller for those of us who don't want the 1550kv 1.5D from Tekin but want a Y wind in that kv to be able to advance timing.
And neil already said the rest I would say, especially towards bashers who can't fit the 1518 in their applications.
Yea, basically I would love seeing more 1.5Y winds from Castle but especially the 1515/1.5Y

Personally I would like to see a 6000+kv 20 series motor, so I can use 1s lipo in my fine design baja 5b conversion... We all know that LV (low voltage) is the way to go for heavier vehicles, and the 1/0 gague wires just look so cool. A special 1 cell version of the XL esc would be cool to, nix the heatsinks for weight savings too, every ounce counts!!!

Also like to see the 17 and 20 series motors with 1/8 shafts, so my current selection of 64p aluminum racing pinions will fit.

All kidding aside I would like to see a longer version of the 17 series motor, like a 1724, with around 1200kv. Would be great with the XL esc on 8s in the various stretched chassis 1/8 scale stuff, and would be an alternative to the big 20 series motors in a lightened or dedicated E chasssis 1/5 scales. And a lower kv version too, for use with 12s when the HV XL comes out, say 780kv. Figuring 35k rpm with nominal lipo voltages here.

1515-1.5Y = 1466kV
1515-2.5D = 1522kV
1415-1.5Y = 1600kV
1415-2.5D = 1660kV
1512-1.5Y = 1800kV

We do sell the 1512-1.5Y today -- it's the 1512-1800Kv motor. (a 1512-1.5Y)

Thanx!

I got a 2833 sitting on my desk right now. It's an eight pole, 200kV, 12kW monster. About 20K RPM on 100V.

Got an application??? :lol:

12kw, so 16hp. Hmm, if you could whip up a 2spd planetary gearbix for it I think we may have a good powerplant for an electric scooter. Or a ride on lawnmower. The scooter would be cool, limit it to around 40-45mph and get about 30-40 mile range.

Or a 1/2 scale rc car.

Hmm. I'm thinking it's time for another visit to your office. But if that motor mysteriously comes up missing, it'll just be a coincidence. :whistle:

PS: You should also have a suitable ESC (and maybe that gearbox linc was talking about) sitting on your desk at the same time. :smile:

1515-1.5Y = 1466kV... perfect truggy motor on 6s! Please make it!

While I'm at it why not a:
1512/2Y 5-6s (Buggy)
1515/2Y 7-8s (Truggy and MT's)
I'm sure a lot of folks would love to run HV/low kv setups and now with the XL ESC there should be motors for it in Y winds (without needing a Baja).
I already posted the need for a 1515/1.5Y too for a truggy on 5-6s.
And to be honest I think it would help sell more of the Mamba XL if we have motors that we can use it in. Like our Truggies and MT's.

Pdelcast, will there also be new rotors for the 1515 motor?
reason i ask is becouse one of mye old 2200kv motor prob need new bearings in near future(better sooner than later i guess) so just wonder if i should wait so i also can get the new redesignd rotor

thanks


(sorry for my grammar\spelling)
