A 3-phase induction motor is rated at 75 kW, 460 V, 60 Hz, 8-pole and has a full-load speed of 1800 rpm. The stator resistance per phase is 0.1 ohm and the stator reactance per phase is 0.4 ohm. Neglecting the rotor resistance and considering the magnetizing reactance as infinite,

calculate:

a) The stator current per phase at full load b) The power factor at full load c) The slip at full load d) The rotor current per phase at full load e) The maximum torque of the motor

Show all steps of your calculation and assumptions made.
