Design and analyse of a circuit which turns a DC motor at a speed which is proportional to how much a temperature is away from a set temperature, and turns: Clockwise when temperature is greater than (say) 25 degrees C. Anticlockwise when the temperature is less than (say) 20 degrees C. Such a circuit might be used to regulate the temperature of a room by turning a ceiling fan to move warm air in/out of that room (using the roof...

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...
