Hello

The formula to use is $M=Kt*I$, whete Kt is Motor torque constant and I=current

The question is as follows Calculate the torque when Current is 5A

Rated torque of the motor is 9,5Nm and rated current 7.9A

To get the motor constant for torque do i simply simply divide the rated torque by rated current and then multiply that by the 5A?
