A three-phase, 480-V, 60-Hz, 6-pole, Y-connected induction motor has its speed controlled by slip power. The circuit parameters are given: Rs=0.06 ohms, Rr=0.05 ohms, Xs=0.2 ohms, Xr=0.3 ohms and Xm=6 ohms. The turn ratio of the rotor to stator winding is n=0.8. The desired speed is 750 rpm. If the rectified current Id = 42.07A and the added resistance is R=9.63 ohms, then the duty cycle would become equal to: = Veuillez choisir une réponse : a. None of these O b. k=0.52 O c. k=0.36 O d. k=0.67
