Torque equation definitionThe torque in the three-phase induction motor is calculated based on rotor current, magnetic flux and power factor.Rotor currentThe rotor current is critical for generating torque and is affected by the induced electromotive force and impedance of the rotor.Starting torqueStarting torque is the torque generated when the induction motor is started. We know that at the beginning of the rotor speed, N is zero.Therefore, just by placing the value of s=1 in the torque equati
