HI
I have a 2200kv brushless motor and use it with 3s lipo. When I increase the input voltage, motor speed (rpm) will increase too. But how about the torque will it increase or decrease at higher voltage? how? why?

The torque will increase if your batteries can supply the current.

Why:

Torque is current dependent. Current is voltage divided by resistance. If the you keep the same resistance and you increase the voltage, the current will go up and therefor the torque will go up.

Thanks for your bare explanation
