56-102 Monster coming down the pipeline

[ray schrauwen]

Kershaw said he would get one for me in August if I paid up front but, he has made mistakes on orders like these with me before so, I passed on it.

For $169 it might not have been a bad gamble.

So has anyone recieved some of these magical mysterious motors yet

[ray schrauwen]

A buddy of mine got a motor from Kershaw but, not shure what he received? It was some "tester" he got at a lower price. Maybe 910kv, not sure.

Even if he has it doesn't mean he will run it this year.

Are you sure it was the Lehner style or was it the Neu looking can?

One problem with this Sky company is their support is....... I guess I'll leave it at that. :-)

Im really curious abouth that big s.o.b. Strange that they (Sky) put it up on their website ~3-4 months ago and still it's nowhere to be found.

Its normal in the Hobby biz for pictures to come out far before the item.

After taking apart a Lehner motor I got from Chris K. (He broke it and Lehner could not fix) and inspecting, I can see why they charge what they do for those motors and I can see why Chris and others invest in them.

I highly doubt you will ever see a real Lehner copy as I jokingly put it in another thread because it would cost the same as a Lehner.

Absoloutely the most amazing construction for a 2 pole motor. The rotors are Neo donut magnets magnetized with the ring splitinto N & S poles. Really cool and the rotor will never explode like some others. Obviously it did fail but, I'm sure it had very aggressive running on it. More than any Chinese motor can take, so far...

[Steven Vaccaro]

What failed? Lets see some pictures....

[ray schrauwen]

I'll post some tonight hopefully.

It's easier to show and tell than to just tell.

[srislash]

I can't wait to check them pics out.

Kind of curious myself - German engineering always amazes me

[Steven Vaccaro]

And also ask Mike pags about how well they are made and how they stand behind their product.

Pics aren't very good, camera sucks, I suck, lol...

I'll try later too with a better camera from the GF.

What it looks like is that the inner windings got heated up and then the rotor may have rubbed a bit until it would not run right anymore.

I can feel inside the windings, sharp edges and some cooked but, not burned enamel from the field windings.

The rotor seems fine to the naked eye but, only Lehner knows. some of the magnets could have partially turned on the shaft there by messing up the alignment of the poles.

Seems to have a definite north & south.

I will check the rotor weight some time when I find that scale. Very heavy in comparison to a 4 pole motor like Neu, Leo, TP.

Very dense power.

What the pictures can't show at this time is the iron surrounding the field inside the can. Can't tell if the windings are woven through or if it is just an Iron ring to increase field strength.

Bearings, no question are top shelf. I might order some from Lehner and give them a try.

Hell of a paper weight and kind of dangerous taken apart. The rotor is super scary strong.

Now, if Leo or TP could make a 4 or 6 pole rotor with that density... Oh, thats called a Neu motor, lol...

The LMT's do have a ring of magnetic back iron, for the smaller motors they are stamped out of I think 0.3mm dynamo sheets, for the bigger 30's series they were laser cut. But it is only the magnetic back iron, they have an ironless core, its pure copper. The german word is "Luftspulenwicklung" but I couldn't find a suitable translation so far.

BTW: Looks definitely like a 2280. How many turns did it have?

I will be testing these shortly. The motors I have are actually 56x102 and 56x112. The 56x112 is almost the exact same physical size as the castle 2028, but without fins. Upon taking them both apart, it's tough to tell the difference.
