Red and Black Brushed Motors


#1

Just found these on banggood. They look really awesome. My eyes couldn’t believe themselves at first. http://www.banggood.com/4X-Racerstar-8520-8_5x20mm-53500RPM-Coreless-Motor-for-Eachine-QX80-QX90-QX95-DIY-FPV-Quadcopter-p-1114280.html?rmmds=searchQO270038868312016028

@Benedikt also has Chaoli working on producing some of these motor color schemes to differentiate the various motors. Will be cool to accessorize the builds with a little color added to the motors :wink:

I’m looking forward to a bit of MMW bling.


#4

They look awesome but 53500rpm doesn’t sound like a lot. I’m not sure but I think it’s about 15.000kV? Does anoyone know the exact formula to calculate those?


#5

Yeah, color coding is great!
I will do this a little more systematic than BG :wink:
Only the fastest will get dark housings.

kV = rpm/V


#6

If they follow the brushless route we might get candy colors!i did see them earlier andgotexcited but no yellow!
:blush:


#7

Yellow would be cool !!


#8

Just saw these in the store:

Love the writing on the motors too

Xbox (and anyone else) The Chaoli spin @ 39,000rpm So whether or not the 55,000 is a lot, it is a 40% jump from the Chaoli.

Colours are good; i had two different speed 6mm motor sets separated but I bumped them and the magnets sucked them all together, now I don’t know which is which! (Is there any way to tell medium from fast in 6mm? Maybe by weight?)


#11

Might have different electrical resistance between the two motor wires. Will definitely have different power draw when loaded at full speed.

It’s multimeter time I think.


#12

Look at the bottoms. chances are they are from different manufactures and have some sort of writing on them - I was able to tell the difference among the Spintechs, Chaoli, and the Nano Stock just from the color of the bottom and the writing.
Good luck
