Question

A 3-phase squirrel cage induction motor, with an applied voltage of 40%,gives a blocked.rotor current of 250% and internal starting torque of 30% of their corresponding
rated values. If an auto transformer limits the starting line current to 150% of the motor full
load current, compute the percen tage starting torque.​

Answer 1

Explanation:

Don't know the answer

but thanks for the points

Answer 2

Answer:

Explanation:

applied voltage=0.4v1

isc=2.5ifl

torque proportional to voltage^2
