Mechanical Power and Developed Torque Total power across the air gap is mechanical power plus power lost in the rotor conductors. ECE 441
There is no provision for mechanical power in this equivalent circuit. The total air gap power delivered to the rotor for all three phases is Power expended in the equivalent rotor resistance, Rr/s. ECE 441
The actual rotor resistance is Rr. The actual heat power expended in the real rotor conductors for all three phases is ECE 441
