- 4 A 3 Phase 415 V 50 Hz 6 Pole Slip Ring Induction Motor Has The Stator Impedance Of 0 75 J2 1 2 Phase And Rotor Imp 1 (30.03 KiB) Viewed 24 times
(4) A 3-phase 415-V 50-Hz 6-pole slip-ring induction motor has the stator impedance of (0.75+j2.1) 2/phase and rotor impedance at standstill of (0.25+j0.9) 2/phase. The stator is delta-connected and the ratio of the stator to rotor turns per phase is 3:2. While the motor is driving a load such that the slip is 4%, two stator leads are suddenly reversed. Calculate the electromagnetic torque immediately after plugging. (78.3 Nm)
