a) Draw the power flow diagram for a 3-phase induction motor. Be sure to show all the loss mechanisms and powers at conversion points. b) Some imported equipment requires a supply of 1000 kW of 60 Hz power. Our local power supply is 50 Hz. The easiest way of generating 60 Hz power is to use a motor-generator set consisting of a synchronous motor directly driving a synchronous generator. How many poles should each of the 2 machines have in order to convert 50 Hz power to 60 Hz power? c) A 50 kW, 500 V, 50 Hz, 2-pole induction motor has a slip of 10% when operating at full-load. i) Find the shaft speed of the motor at full load. ii) What is the rotor frequency at full load? iii) Determine the load at full torque.
