I bought some motors and they are Skystar 2207 2550KV, cant find any table for peak current rating, i have a 35A ESC, REV BS-35A BL_heli_S.
These motors are seemingly of good quality with very good winding, titanium hollow shaft, O-ring on shaft..but not sure about the ratings
I am afraid to damage my ESC on these motors and cannot really bench test the max current draw of these, the props i am using are Dalprop Cyclone T5045C Pro..
Is it possible to scale motor output in BF PID tuning setup allowing not to draw on their peak power / max currrent.
Will it help or is there any other way to limit the motors below my ESC’s rating

No way to limit the motor. The motor will pull as much amp as it need.

You can limit the ESC, but Blheli_S do not have this function. And even if have this function, it is not recommended that you limit the ESC.

You can reduce throttle output in BFC. But the question is, how will you limit the throttle if you don't know the max amp draw?

If you are tech sevvy, you can test to see what amp draw the motor is pulling.

But to check the draw i need a bigger esc right?
The seller has give data for 1950KV motor, can we guess peak current from this data for 2550KV?

As long as you don't blast throttle to 100%, you can gradually increase throttle until you hit 35A.

Files you linked are not open.

What if i clip or scale throttle limit in betaflight?

it doesnt prevent befor 100% throttle request by the flightcontroller. if its needed for the movement the flghtcontroller will still command 100% to single motors.


edit: the racerstar esc you are using works great, we used it for parkhouse...
personal i would expect up to 45amps from kv and motorsize only, thats just the peak. i believe the particular esc can handle that peak for a short time, i would trust in this particular esc and use it with your motors without care about any limit or hide full throttle...
lightweight skinny props might be a bit better for the esc, some gemfan 5146,6.
personal opinion about from my experiences with that esc.

Yes, this seems a logical answer, single motor can get 100% depending upon the orientation and set-point..
Hoping for the best will try not be harsh on throttle..
I hope snap flips and rolls wont cause any damage
Do you know the best scale value for current sensor of this ESC, i am at 190..

Links can be accessed now i think

the peak current on the 4s version (2550kv) will be higher, even as 1950kv is very high for 6s.
i just believe it might be up to 45a.

i dont know a matching value about curremt sensor

I would agree, 45-50A on 4S.
