Tekno RC Neu or Orig Neu

[DRIFT_BUGGY]

Sweet, be sure to post back on how it performs

[George16]

Guys, you can check out on y build here: http://www.rc-monster.com/forum/showthread.php?t=12463

I just updated it with more pictures. As usual, any comments or tips are greatly appreciated.

Hello,

Just to clarify, these are exactly the same inside as all of the newer Neu motors. All of the newer motors have an updated stator/rotor design to reduce cogging. It is not specific to our version, but rather a new thing for all Neu 1515 and some 1512 motors (not sure about the other sizes). Older Neu's will be harder to turn by hand. FYI :)

Thanks for the clarification. I just receive my Neu today . However, on you website, you stated that a selection of winds will be available to suit 3, 4, 5, and 6s 1/8th scale buggy and truggy applications.How would I know which one I got since the motor did not come with anything (spec sheet, instruction etc)? I'll be running mine on 6S.

Straight on the Tekno RC website it posted that the motor is hand made:

* These are genuine hand-built Neu motors, not mass produced

Thanks for the clarification. I read it on this forum in one of the first threads about the new tekno Neu.

With this info than, even though I have an older one, it sound like the newer versions would be better.

That what it sounds like but this phrase got me wondering: a selection of winds will be available to suit 3, 4, 5, and 6s 1/8th scale buggy and truggy applications.

Wye and Delta or number of windings?

Or could be both. So, what if I got a motor for 3S and I'm using 6S?

You'll have a motor turning twice as fast than it is rated for -

I think by 3s, 4s, 5s, etc they mean a motor selection appropriate for running on each of the number of cells.

ie: 2200kv for 4S, 1700 for 5S, etc.

That's exactly right.

[mkrusedc]

So help an electric noob out. Why is the Neu 1515 1y 2200kv best run on 5s?

2200rpm * 4s * 4.2V/cell = 36,960rpm
2200rpm * 5s * 4.2V/cell = 46,200rpm
2200rpm * 6s * 4.2V/cell = 55,440rpm
neu says top limit is 60,000rpm

the closer to that limit, the more wear on the bearings.

[TexasSP]

But you're not going to get 4.2 volts per cell under full load.

[BrianG]

Not only don't lipos stay at 4.2v/cell for very long at all, but any amount of current reduces the kv rating...
