More 540C-7XL inside pics

I think the hackers use segmented magnets.

I just found this pic on the net of a C50 which was opened..

lol, the link takes you to a little logo...

I don't know what you are seeing, but i tried it from another IP address and was able to see the picture..

does that rotor fit in a feigao/wanderer motor?

[zeropointbug]

what the bleep, why is it so greasy and fried looking.

...I have a cousin in Holland named Niels.... it that you?! lol

[coolhandcountry]

I always wonder why the cools are not straight in the middle where the rotor runs.

[zeropointbug]

BTW, it looks like the 3-phase wires coming out are actually all the wires from the motor just bundled up and then strung out and soldered together...

Can anyone confirm this?

[smhertzog]

Having a can that is a finned heat sink is a very nice option it seams like it would transfer heat much more efficiently than an add on heat sink. Even with artic silver a bolt or clip on heat sink wouldn't transfer the heat as well. It would be interesting to see a comparison of the two to see how much of a difference it is.:032:

Yes Zero, it are all the wires from the coils.


The reason it looks so bad, is because these come from a fried C50

[zeropointbug]

Serum, ah, icic

smhertzog, yes, an integrated heatsink in the motor can would transfer heat much better, it's quite thin, there is probably 4 times more surface area than a smooth can version; PLUS the heatsink IS the can, so its the entire circumference of the can. Im sure it will run up to 20 degrees F cooler than a bare can.

One thing i don't like about the 540C-xxx motors is the mounting screw holes which are two beside each other on each side of the shaft, whereas the smooth can motors have 1 hole every 90 degrees from the next. This doesn't leave to much for mounting options... or maybe i could just make a mount for it and than make the mount adjustable instead? (for changing pinions)

there is a slight design flaw in feigoas integrated heatsink design that limits it usefulness somewhat.
On the 380c motors there are fins but nowhere for the air to escape or flow thus it would create an air pocket in-between these fins.
The bottom line is they tried to emulate the c40 and kontronik twist motors using and extruded section with fins for the casing but in the end this means the arrangement of the fins is inferior to that of the c40 and twist motors

[zeropointbug]

Yah, the 380 size motors the fins are circumventing around the can, the 540C cans the fins are length-wise so if it up in the path of air flow, it will be kept quite a bit cooler that the smooth can versions.

[zeropointbug]

I think? Is that true for the 380 motors?
