7.15. A three-phase, 460 V, 60 Hz, 1760 rpm, wound-rotor induction motor has the following equivalent circuit parameters Ri=0.25 ohm : R'= 0.2 ohm : Xi = 1.2 ohm : X2,= 1.1 ohm : 'Ku = 35 ohm The motor is connected to a 3ph, 460V, 60Hz supply and is star-connected. Use the simplified equivalent circuit. Initially the external rotor resistance is set to zero. (a) Calculate the speed (in rpm) at which...
. A three-phase, 460V, 60Hz, 4 – pole Y – connected induction motor has the following equivalent circuit parameters: Rs = 0.42Ω, Rr ′ = 0.23Ω, Xs = Xr ′ =0.82Ω, and Xm = 22Ω. The no load loss Ploss = 60W, assumed as a constant. The rotor speed is 1750 rpm.Use the approximate equivalent circuit ( i.e. the Xm branch is at the very left of the circuit) determine the followinga. the synchronous speedb. the slip sc. the input...
. A 460-V 460-V, 25-hp, 60-Hz, six-pole, Y-connected induction motor has the following impedanc ohms per phase referred to the stator circuit. Ri= 0.212 R2 = 0.282 X1 = 1.055 12 X2 = 1.055 22 XM = 33.9 W The total rotational losses are 1100 W and are assumed to be constant. The core loss is lumped with the rotational losses. For a rotor slip of 4% at the rated voltage and rated frequency, a) The input power b) Peony...
