ELECTRIC MACHINERY & TRANSFORMERS

The book provides in-depth coverage of the complex theory and practical engineering methods pertaining to rotating machinery. The second edition introduces AC motor efficiency using machine constants as well as using the perunit (p.u.) system for calculation of efficiency and regulation of machines and transformers. Completely in conformity with the IEEE standards, this book is a valuable learning tool and a reliable reference for students as well as practicing engineers. For Sale in Indian subcontinent onlyFeatures Updates coverage of specialized machines to include stepper motors, linear motors, magnetic-levitation devices (MAGLEVS) and high-speed surface transport (HSST) vehicles. Uses figures with text to enhance understanding, places lenghy derivations of equations in an appendix to avoid interruption of the flow of material, ad adds a unique equivalent circuit diagram to develop motor constants from running-light and blocked rotor tests. Follows the format method of mesh analysis for induction of motor horse power and efficiency, using derived motor constants.
