Electrical machines can be broadly classified into two categories: rotating machines and static machines. Rotating machines, such as motors and generators, convert electrical energy into mechanical energy or vice versa through electromagnetic interactions. Static machines, such as transformers and inductors, transfer energy between two or more circuits through electromagnetic induction.
The author explains the different types of DC machines, such as DC motors, DC generators, and DC converters. He also discusses the various methods of speed control, such as armature voltage control, field current control, and power electronic control. vk mehta electrical machines
Each chapter follows a repetitive, learner-friendly pattern: theory, derivations, solved examples, and a rich set of practice problems. Electrical machines can be broadly classified into two
V.K. Mehta’s Principles of Electrical Machines is not a revolutionary text, nor does it claim to be. Its greatness lies in its utility as a teaching and learning instrument. By prioritizing clarity, step-by-step reasoning, and extensive practice material, it demystifies a traditionally difficult subject. For any student seeking to build a reliable foundation in electrical machines—whether for passing semester exams, clearing competitive tests, or understanding real-world motors and generators—this book remains an exceptionally useful companion. As long as electrical engineering curricula include basic machines, Mehta’s text will continue to be a trusted first port of call. The author explains the different types of DC
