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 Prise...
