Gupta focuses heavily on performance characteristics such as: Efficiency and Losses:
A comprehensive study of electrical machines requires a bridge between abstract electromagnetic theory and the gritty reality of physical hardware. J.B. Gupta’s Theory and Performance of Electrical Machines ---- Theory And Performance Of Electrical Machines By J.b.
J.B. emphasizes the (oscillations in rotor angle due to sudden load changes) and the use of damper windings to suppress it. ---- Theory And Performance Of Electrical Machines By J.b.
