Electrical Machines By Jb Gupta -

The textbook is structured logically, moving from foundational electromagnetic principles to complex machine operations. The core subjects include:

6. Three-Phase Induction Motors: Construction (squirrel cage, slip ring), rotating magnetic field, slip, torque-slip characteristics, equivalent circuit, power stages, starting methods (star-delta, auto-transformer, rotor resistance), speed control, cogging, crawling. 7. Single-Phase Induction Motors: Double-revolving field theory, starting methods (split-phase, capacitor-start, shaded-pole), equivalent circuit. electrical machines by jb gupta
