problem 1:

Illustrate out the criterion for selection of the motor drive.

problem 2:

Illustrate the starting and running characteristics of three (3) phase induction motor.

problem 3:

A d.c. series motor drives the load torque of which diverges as the square of speed. The motor takes a current of 25A when the speed is 500 rpm. Find out the speed and the current when the field winding is shunted by the diverter whose resistance is twice that of field winding. Neglect all losses.

problem 4:

describe about different types of loads. What do you understand by the term load equalization? What is its importance?

problem 5:

Illustrate out different construction and operation of different furnaces employed for induction heating? Discuss their relative merits and demerits.

problem 6:

Find out the amount of energy needed to melt brass at the rate of one tone per hour in the single phase Ajax Wyatt furnace. Specific heat of Brass= 0.094, Latent heat of fusion = 40 kcal/Kg, Initial Temperature = 240C, Melting point of Brass = 9200C. Assume the efficiency to be 65%.
