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

This is a great place to get familiar with motors and more

Artur

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.

Well, I discovered interesting moment with Feigao motor. During re-soldering motor connectors, I noticed that solder doesn’t stick nicely to all conductors; further investigation showed that wire wasn’t properly striped from insulation to start from. So I rechecked the rest, and found out same thing with the rest. Maybe my motor was special but it was recent purchase, 7XL to be specific.
Loose phase wire cannot be good for motor or controller, not mentioning total phase current capacity and resistance (inductance interesting to check).

Artur

I thought the nemesis is the same ?

I was always told that to. But the magnet looks different. It seems to be better constructed cause feigao will leave play in theres and nemisis doesn't. Not on the three I have bought.

Batfish.........You hit the nail on the Head for me :L:

Well what a thread I've kept up so far........popcorn's just a distant memory now:)

for me, the wealth of knowledge on this forum continues to amaze.

thanks

I wonder if the wanderer has a segmented magnet. looks wise it resembles the nemisis

This is a segmented rotor of a Kontronik FUN480-42 motor.

A clearer one.

The internal parts of the can.

Last one.

Cool. What are the dimensions of the rotor?

I have not measured it, yet. Probably 25+mm. The can is 49mm long and 29mm wide.
