Lehner 2280, Fried.. How good is Lehner's Warranty.?

[Peter Zicha]

this topic was brought up on rumrunners forum , these guys have both but apparently the only difference between the two is the rear endbell

The rotor of both motors is identical, from my understanding. The stator is different , only because the wires are sticking out. The high-amp doesnt have the wye/delta changing option either:

this reduces the internal resistance, since there are less solder contacts.

Having red a comparision (in german) between a Neu 1515 (340/360gr) and a lehner 1950 (355gr) stating there is no big difference in Power output (only different efficiency points) i think it's fair to compare a Lehner 2280 and a Neu 1527 looking at their wheight.

Wheightwise a Neu 1527 is more comparable with a lehner 2250. A Lehner 2280 wheighs 200-250gr more then a Neu 1527. It is also longer and has a bigger diameter. I think this allone should be sufficient to tell which motor can handle more power since both do claim efficiencies around 90% and both do only cook with water (or should i say copper ...).

BTW windings of the Neu motors do come from Mexico.

There is a good write up (in german though) on Neu Motors (with pictures and diagrams) with a comparision of a Neu 1515 and a Lehner 1950 on this site. By using babelfish you could translate this website.

Very interesting write up....thanks for posting it

Sorry for your LMT loss and hopefully U will get it back in no time.
I do like them both Neu and LMT but I will agree that in terms of balancing Lehners are on the shy side, while none of them will match quality of pletts, just from observation and testing.

Interesting fellows on the boats forum, maybe I should mod couple ESC's for them :)
But, so far nothing then end-bell from this link.

Extra charge for proper, cheaper, simpler end-bell doesn't sounds like German.
What I've read some time ago (and cannot find it anymore, even on the LMT-site they now referring to end-bell difference only!?) that wire gauge was different as well...

Griffin....mod them as in how.............................................

I agree with you said about the pletts , there quality is second to none , I have 3 brushless pletts and three brushed all ( 355's )

With water cooling on-demand you can draw ridiculous amount of Amps with smart layout. All the same more Amps, better cooling.

-I do love brushed 355-series, two of them were placed in my neighbors barbi-jeep you can imagine what a joy it was in conjunction with optima battery :)

Something like this , I have a lathe and a CNC mill , I mod all my own and also swap the battery cables out to 8awg

Being a plett fan you should enjoy this 355/50/06 and mini berkley jet drive

Sweet!!!

there's is such a big size difference from the neu 1527 and the 2280 hi-amp... that's why it is hard to believe that the power outputs are similar... but I hope that the neu 1527 are just as powerful... I guess we'll see when I get it... and if I ever get the 2280 back by 2010... haaahhaah

Lehner charges more for the rotors of the hi amp motors...
those heatsinks are awesome, I saw them a while back when the OEMRC escs came out...

I really don't think the 1527 can compare to the 2280-5 Hi-Amp... just being able to pull close to 400Amps is crazy... probably will never pull that..

Soon as I get my motors, I'll do a comparison... same batteries, same esc, same vehicle... :)

Are you serious that the Neus come from Mexico?.. it worries me... but the efficiencies are great according to everyone else...

I think the Neu is as powerful mainly because it's a 4 pole motor. It will naturally make more torque and electric motors also makes power from torque. Have you ever wondered why some people love the outrunners ?

Its like:
2Pole inrunner - Good petrol engine :D
4Pole+ inrunner - supercharged petrol engine :P
Outrunner- Diesel engine ;)

Based on the write up i posted, Neus are assembled in San Diego (Neutronics) but the windings are handwound in Mexico.

AWESOME!!.. I really can't wait untill they come in....

I just wonder why the heck it's taking so long to get the neumotors in... I know the lehner, I had to wait for almost 3 months...
