Design of Rotating Electrical Machines, 2ed

Details

This book is an in-depth essential reference of rotating electrical machine design theory and application.  In the first part of the book the general theory governing the design of an electrical machine is presented; addressing the necessary fundamentals of electromagnetic theory; exploring possible winding arrangements and resistances; describing the behaviour of the magnetic circuit and flux leakage.  After this introduction of principles the main body of the book focuses on the design of a rotating electrical machine.
