7-30.The no-load and blocked-rotor tests conducted on a 110-V, single-phase induction motor yield these data: No-load test: Input voltage = 110 V Input current = 3.7 A Input power =

50 W Blocked-rotor test: Input voltage = 50 V Input current = 5.6 A Taking the stator resistance to be 2.0 Q. friction and windage loss to be 7 W, and assuming X11=X'12, determine the parameters of the double-revolving-field equivalent circuit.
