The full load torque of an induction motor does NOT depend on

Concept:

The torque equation of the three-phase induction motor is given as

\(T =\frac{3\times E_{2}\times I_{2}\times Cos\phi}{\omega } \)

\(T = \frac{3}{{2\pi {N_s}}}\frac{{sE_2^2}}{{R_2^2 + {{(s{X_2})}^2}}}\)

Rotor current \({I_2} = \frac{{s{E_2}}}{{{Z_2}}}\)

Ns = speed of the motor

s = slip of the motor

R2 = rotor resistance

X2 = rotor reactance

E2 = rotor-induced emf

\(Cos\phi = Power factor\)

Hence it's independent of the type of machine.
