Textbook in PDF format

The contribution of Electrical Machines is enormous in the present technological world. A number of new variants of basic machines have been developed in the past years and new topologies have emerged such as permanent magnet machine, reluctance machine, brushless DC. machines and linear machines. Apart from the design and basic structure of machines, their control algorithm is another aspect where effort is being made worldwide. Nevertheless the basic underlying principle of operation remains more or less same for all types of machines. It is this fundamental concept where emphasis is being put in the present textbook. Spread in 12 chapters the book broadly Review of Basic Circuits / Review of Basic Laws / Magnetic Circuits / Principles of Electromechanical Energy Conversion / Transformers / Direct Current Generators / DC Motors / Induction Machines / Synchronous Generators / Synchronous Motors / Single Phase IM / Appendix Trignometric Relations; Appendix Laplace Transform; Appendix Symbols; Appendix Units / Conversions / References / Index Undergraduate and Postgraduate Students Electrical Engineering
