The rotor resistance and reactance of a squirrel-cage induction motor rotor at standstill are 0.14 ohm per phase and 0.8 ohm per phase respectively. Assuming a transformer ratio of unity, from the eight-pole stator having a phase voltage of 254 at 60 Hz to the rotor secondary, calculate the following
A. rotor starting current per phase
B. the value of slip producing maximum torque
