: Double revolving field theory and types like split-phase, capacitor-start, and shaded-pole motors.
In many remote areas or during online semesters (post-COVID), physical bookstores were closed. The PDF was the only way to continue learning.
In the hierarchy of electrical engineering literature, few names command as much familiarity among students and professionals in the Indian subcontinent as J.B. Gupta. His texts are often considered the bridging blueprints between abstract electromagnetic physics and practical industrial application. While volume one typically handles Direct Current (DC) machinery and transformers, Electrical Machines-II
Principle of operation, starting methods, and phasor diagrams. Single Phase Induction Motors:
Gupta provides a rigorous mathematical and graphical proof showing that when three-phase currents, displaced in time by 120 raised to the composed with power , are fed into a three-phase winding displaced in space by 120 raised to the composed with power
Electrical Machines 2 by J.B. Gupta is a popular textbook for several reasons:
