The rotor of a 6 pole, 3 phase, 60 Hz induction motor has per phase resistance and reactance of 0.1 Ω and 0.5 Ω respectively. The voltage induced per phase in the rotor at standstill condition is 150 V. When the motor develops maximum torque, the rotor current per phase will be

• A. 150 A
• B. 150 \(\sqrt{2}\) A
• C. 750 A
• D. 750 \(\sqrt{2}\) A
