In a 3-phase induction motor, maximum torque is independent of:
AStator supply voltage
BStator leakage reactance
CRotor resistance at standstill
DSynchronous speed
Explanation
The maximum (breakdown) torque of a 3-phase induction motor depends on supply voltage, synchronous speed, and leakage reactances, but is independent of rotor resistance. Changing rotor resistance shifts the slip at which maximum torque occurs without changing its magnitude.
