Preface

In recent years Electrical Machnes: Principles, Designs & Applications are being used extensively in Electrical Engineering, Microprocessor, Electrical Drives and Power Electronics research and many other things. This rapid progress in Electrical & Electronics Engineering has created an increasing demand for trained Electrical Engineering personnel.

This book is intended for the undergraduate and postgraduate students specializing in Electronics Engineering. It will also serve as reference material for engineers employed in industry. The fundamental concepts and principles behind electronics engineering are explained in a simple, easy- to- understand manner. Each chapter contains a large number of solved example or problem which will help the students in problem solving and designing of Electronics system. This text book is organized into thirteen chapters.

Chapter-1: Three Phase Circuits

Chapter 2: DC Motor and Generator

Chapter-3: Stepper Motor, Induction Motor and AC Series Motor

Chapter-4: Transformer

Chapter- 5: Switchgear, Protection & Earthing System

Chapter- 6: Electricity Usage Monitors, Power Factor Correction and Basics of Battery & Its applications

I do hope that the text book in the present form will meet the requirement of the students doing graduation in Electronics & Communication Engineering, Computer Science Engineering, Information Technology, Electronics & Instrumentation Engineering and Electrical & Electronics Engineering. I will appreciate any suggestions from students and faculty members alike so that we can strive to make the text book more useful in the edition to come.
