At full-load torque, the motor speed is 580 rpm. A FWM converter drives the motor. Calculate the duty ratio that limits the dynamic braking current to twice the rated value.
A 60 Hz, 480 V, three-phase, Y-connected induction machine has the following
parameters:
Assume it is a 12 pole machine. The assumption is made because, at full load, the
slip is close to zero and P = 12 satisfies this condition.
