If you want to move beyond induction motors and understand the motors that power the 21st century (EVs, robots, medical devices), keep this book on your desk.
Mastering the “Specials”: Why K. Venkataratnam’s Book is a Must-Have for Electrical Engineers Special Electrical Machines By K Venkataratnam
The book aligns very well with the syllabi of major technical universities (JNTU, VTU, Anna University, etc.) and competitive exams like GATE. It strikes the right balance: rigorous enough for postgraduates, but accessible enough for final-year undergraduates. If you want to move beyond induction motors
For students and practicing engineers in India and beyond, one name stands out when learning this subject: . His book, simply titled Special Electrical Machines , has become the gold standard for understanding these complex, non-conventional machines. It strikes the right balance: rigorous enough for
A special machine is useless without its drive. Unlike older texts that treat the machine and its power electronics separately, Venkataratnam integrates the discussion. He explains how the electronic switches (transistors, thyristors) fire to create the rotating magnetic field. You learn not just why a BLDC motor turns, but how the Hall sensors and inverter coordinate to make it happen.
