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)
