Problem 1: A 208-V four-pole 60-Hz Y-connected wound-rotor induction motor is rated at 30 hp. Its equivalent circuit components are Xm = 10 12 = Pcore = 400 W SCL R1 = 0.1.12 R2 = 0.072 X, = 0.21 Ω x2 = 0.2112 Prot,loss = 500 W For a slip of 0.05, find (a) The line current I, (b) The stator copper losses Pscu (c) The air-gap power PAG (d) The power converted from electrical to mechanical form Pcom (e) The induced torque Tind The load torque Tload (g) The overall machine efficiency (h) The motor speed in revolutions per minute and radians per second Notes: 1. Use the IEEE-recommended equivalent circuit to solve Problem 1. 2- All indicated parameters are already refereed to the stator side.
