A multicolor edition of Vol.II of A Textbook of Electrical Technology to keep pace with the ever-increasing scope of essential and morden technical information, the syllabi are frequently revised.This often result into compressing established facts to accommodate recent information in the syllabi.Fields of power-electronics and industrial power-conditioners have grown considerably resulting into changed priority of topics related to electrical machines.Switched reluctance-motors tend to threaten the most popular squirrel-cage induction motors due to their increased ruggedness, better performance including controllability and equal ease with which they suit rotary as well as linear-motion-applications.If a star-delta starter is used, what is the starting torque and starting current ? Neglect magnetising ... The short-circuit current of the motor at normal voltage is 5 times the full-load current and the full-load slip is 4 per cent. [(a) 0.33 (b) 0.25] ( A.C.anbsp;...
