Neu motors came in
 

New motors came in, Wow, I didn't realized that different winds had different wire thickness... I hope these neu's work well.. Reason..

1 They cheaped out and didn't use the bushing for 3 of the motor wires(one motor), only used shrink wrap.

2 Shafts where all different lengths.

3 Three of the motor shafts were cut and rounded very well, one looked like it was cut with a grinder or dremel.


I'm sure it's nothing big, but the consistancy is just not there... Because all of the German made motors, everything was consistant... Maybe I'm wrong?

Looks like they did not work on 2 of the motor shafts. They probably forgot to turn them down to the same length.

Well I wouldn't doubt the consistency on the Lehner... it reads ISO 9001 right on the motor there, which is a quality control/manufacturing standards certification.

Just' giving a bad taste in my mouth when I got my first batch and I noticed small things like that... I've never noticed these things with my lehner motors.. But they could've just forgot... It just sucks thinking of what other bigger mistakes it could lead to... something so small and preventable.. Shoot, If i only bought one, I would have never noticed anything....

Cool it. LOL they are just shafts. The longer the better! I bet girls will choose the motors with the longer shafts. It is their instincts. kidding. Dun kill me for me. :lol:

Oh yeah!!! nothing wrong with the shafts.. and nothing wrong with the motors either.. but when you spend that kind of money, it's about quality/workmanship. Know what I mean, first a shaft, then a bushing, then what next?...

I can assure you, I have own quite a few Neu's and have seen most of Linc's collection of Neu's. They are hand-built quality! Extremely nice and smooth. Never had a problem yet.

However, I haven't had 4 of the same motors in my hands to compare. I wonder if its just a different person building different winds?

Well, I can't comment on the shaft lengths or the lack of bushing on the wires (QC falling looks to me), but the wind thickness makes sense. Motors of a physical length are all gonna be rated for about the same amount of power. So, for X amount of power, higher winds will draw less current and so the winds aren't as thick. Plus, the fewer wind motors most likely use larger coil wire (or multiple to make up a larger one).

Leave it to the experts and you questions will be answered:lol:

Not an expert, but an "armchair professional". :smile:

At least you admit to being lazy...

From my limited (HA) experience with various motors the neu seem to be the best out there. Generally the external looks are a bit questionable (black motor with crappy sticker) and I have noticed the variety of shaft materials that neu seems to use. I have a feeling you have a few different age stators in those motors, that would account for the differences in the shaft length and appearance. I once returned a neu with a fault stator and got a heli model stator back, the shaft must have been 1.5" long... Kinda funny, I just trimmed it down to the correct length and ground a flat spot on it.

I do understand your feeling s though, these motors are not cheap, and if I bought them neu I would be concerned about these same things. I guess function beats form, at least for me.

Yes, they would use a 30+ gauge wire and just wind them in a bundle... obvious reason being you can't wind 12awg or 10awg thick wires around a stator, at least not safely (damaging wire insulation).

This makes me ask the question, the people who have had problems with breaking motor wire leads, what Kv. winds were they? I can see the high Kv. winds having the problems... my 1512/3D has had zero issues with wire breakage and I have moved, readjusted, kinked the leads many times. They look to me like they would be about 12awg wire size equivalent.

Date of manufacture could explain some differences, they make changes from time to time. They never used to put the bushings around the wire at all, just heatshrink.

It's what's inside that counts :tongue: The only German motor I've ever had chunked it's bearings and fell apart (literally) within just a few hours of use. Typically German, great for a little while and then it all goes horribly wrong. Looks like a hiccup on the QC team's part, but it really isn't anything to worry about.

WTF are you doing with $1000+ in motors???
