A two pole induction motor is to be used to drive a very heavy mixer in the cement industry. Three phase rated voltage and frequency in Pakistan is known to be 440 V and 50 Hz respectively. This 100.56 hp machine is essentially a three-phase machine with Y configuration. You have to analyze the behavior of the machine for which one has to know the parameters of the equivalent circuit, they are mentioned below: XM = 7.2 ohms Pmisc = 250 W PF&W = 0.5 KW X1 = 0.17 ohms X2 = 0.17 ohms R2 = 0.056 ohms Pcore = 11 kW R1 = 0.075 ohms %3D If the slip of motor is 4 %, by analyzing the equivalent circuit, determine the following values. a) Stator copper losses b) Air gap power c) Amount of power converted from electrical to mechanical
