Electrical Machines by S. K. Bhattacharya is a comprehensive book that provides a thorough knowledge of electrical machines to students and engineers alike. It is one of the best books on electrical machines available in the market.
The book starts with an introduction to electrical machines, their classification, and basic principles. It then explains the construction, working, and characteristics of different types of DC machines, such as generators, motors, and starters. It also discusses the methods of testing, speed control, and efficiency improvement of DC machines.
The next part of the book deals with transformers, which are essential devices for power transmission and distribution. It covers the topics of transformer construction, operation, equivalent circuit, phasor diagram, losses, efficiency, regulation, testing, and parallel operation. It also introduces the concepts of auto-transformers, three-phase transformers, and special transformers.
The third part of the book focuses on synchronous machines, which are used for power generation and power factor correction. It covers the topics of synchronous generator construction, operation, emf equation, phasor diagram, armature reaction, voltage regulation, parallel operation, and load sharing. It also covers the topics of synchronous motor construction, operation, starting methods, torque equation, power angle curve, hunting and damping, and applications.
The last part of the book covers induction machines, which are widely used for industrial applications. It covers the topics of induction motor construction, operation, equivalent circuit, torque-slip characteristic, losses and efficiency, starting methods, speed control methods, braking methods, and testing. It also covers the topics of induction generator construction, operation, and applications.
The book also contains a chapter on special machines, such as stepper motors, brushless DC motors, switched reluctance motors, permanent magnet synchronous motors, and linear induction motors. It explains the construction, operation, and applications of these machines, as well as their advantages and disadvantages over conventional machines.
The book concludes with a chapter on electrical machine design, which covers the basic principles and methods of designing different types of electrical machines. It also discusses the factors affecting the design, such as materials, cooling, insulation, losses, efficiency, and cost. It provides some examples of design calculations for various machines.
