And I will encourage you to do that.
I learn new things every time I read somebody’s post, doesn’t matter how good or bad it is, right or wrong for that matter.

Thanks, Artur. I'll surely do my best.

Artur,

I know my thing about an airgap, i just told you that i understood DIFFERENT from another post of yours in this thread.

To tell you the truth, i've got the feeling that you are not completely aware what your talking about. In another post, you recommended a user to get 2 18.61's to one set of 12 cells. (good when you want to kill your cells for sure!)

Appearantly you did hear something;

Wrong for motor type we discuss. Both magnetic fields are synchronized.

ANY magnet and has got this character. otherwise you would have 0 lost. It is about the difference in speed of the electric magnetical field AND the slower moving magnet! who are you to argue about this?

About your last quote;
I was talking about audio transformers to explain something to you

And here it gets interesting to me;

Quote:

Every motor comes with inductive/capacitive/resistive ratings for phases. And based on them you can define what frequency response you get and what switching frequence to use and how efficiency will lay across
RPM range.

Show me the formula please!

Just dont start a fight here, or else somthing really bad is gonna happen!

I have nothing to say here...

Maybe that will help with L/C/R... (from google)

How do you unsubscribe to a thread?;)

i think you can disable it when the email comes up saying that someone has replied to the thread you have subscribed to(there is a link close to the bottom of the email that unsubscribes you)i think

That is why I'll never ever debate in futile topics like this in the future. EVER.

Upon further review I noticed something today. http://www.rc-monster.com/forum/show...5&pagenumber=2
2nd post is a pic of a nemisis rotor. Is it segmented.

Yes, it is. Just like the Kontroniks.

More like easy to reuse the same magnets...

But after long discussion I decided to finish building electric dyno and put some real numbers.

Artur

and you are able to do partitial load efficiency on a proper way too?

that is what this is all about afterall..

Arthur, i agree with you on the 'cost down' reason for segmenting the feigao magnets.

the XL is 45 mm (3 magnets) the L is 30 mm (2 magnets)

Tank you Leroy. Do you know the diameter of this Novak rotor??

Those "blocks" of the Feigao are not really fine segments, IMHO.

That is not a feigao.The feigao is not like that. it is one smooth flat armature. That is a nemisis. I took a measure ment of my screw holder. I mean the hv armature. :D it is about 14 mm x 45 mm. it is like a 380 size.
