Three Phase Induction Motors: Condition for Maximum Starting Torque

 

CONDITION FOR MAXIMUM STARTING TORQUE

 

Starting torque is maximum when rotor resistance equals rotor reactance.


The condition for maximum torque may be obtained by differentiating the above expression with respect to R2 and then putting it equal to zero.


∴ K2 [R22 + X22 − 2R22] = 0

X22 ‒ R22 =0

X22 = R22

X2 = R2             ………….(5.12)
