Re: VESC as multirotor ESC?

I just tested the VESC6 with a 36N42P motor and a 30 inch propeller. I looks nice, I have tested at 6S (22.2V) and it works very well, This graph is some seconds of hand throttle with a servo tester conected through PPM. 60A.JPG I'm surprised that only at 6S it easily reaches 60 amps limit during ac...

Re: VESC as multirotor ESC?

arvidb,

Thanks, yes, you are right, "VESC Six will remove the 60k ERPM limit and has been tested around 150k ERPM from what i've heard and seen on Benjamin's test videos"

15000/21 = 7140rpm is enought!!!

Motors are 100 or 110kv *52V = never more than 5500rpm

Re: VESC as multirotor ESC?

yes, i have a VESC6, but i have not tested too much.

I have realized the ERPM limit could be a problem

This kind of big multicopters motors have a 36N42P scheme, 42 magnets is 21 pole pairs?
60000erpm /21 = 2850rpm?

Is it correct this calculation?

Re: VESC as multirotor ESC?

But 14S by changing mosfet to IRFS7730-7PPBF???
14S is 58.8V (full charged)

Re: vesc on a multicopter

I am also curious about VESC on multicopters. we are testing FOC ESCs and it seems much better than BLDC ESCs. We are using 30inch propellers and RPM are about 4000rpm never more than 4500rpm, and motors are 24-slot/28-pole (than i remember). I don't know how to calculate ERPM but i am sure it is ok...
