The torque of a 3-phase induction motor is given by:
\(T={3\over ω_s}{V^2\over ({R_2\over s}^2)+X_2^2}{R_2\over s}\)
where, V = Supply voltage
ωs = Synchronous speed in rad/sec
R2 = Rotor resistance
X2 = Rotor reactance
s = Slip
Among the following options, the starting torque does not depend on Field excitation during startup.
