engineering recuitment GATE EE 2023-24 Test Series Electrical Machines Three Phase Induction Motor Induction Motor Torque Speed Characteristics
A 3000 V, 24 pole, 50 Hz, 3-phase, star connected induction motor has a slip ring rotor of resistance 0.016 Ω and stand still reactance 0.265 Ω per phase.
Full load torque is obtained at a speed of 247 rev per minute. Neglect rotor impedance.
Estimate the ratio of maximum to full load torque.Enter numerical value using the virtual keypad. Round off where necessary.
