Book excerpt: Induction Machines Handbook: Steady State Modeling and Performance offers a thorough treatment of steady-state induction machines (IM), the most used electric motor (generator) in rather constant or variable speed drives, forever lower energy consumption and higher productivity in basically all industries, from home appliances, through robotics to e-transport and wind energy conversion. Chapter 1 offers a detailed introduction from fundamental principles to topological classifications and most important applications and power ranges from tens of W to tens of MW. Then individual Chapters 2 and 4 deal in detail with specific issues, such as Magnetic, electric, and insulation materials Electric windings and their mmf Magnetization curve and inductance Leakage inductances and resistances Steady-state equivalent circuit and performance Starting and speed control methods Skin and on-load saturation effects Field harmonics, parasitic torques, radial forces, noise Losses Thermal modeling Single-phase induction machine basics Single-phase induction motors: steady-state modeling and performance Fully revised and updated to reflect the last decade’s progress in the field, this third edition adds new sections, such as Multiphase and multilayer tooth-wound coil windings The brushless doubly fed induction machine (BDFIM) Equivalent circuits for BDFIM Control principles for doubly fed IM Magnetic saturation effects on current and torque versus slip curves Rotor leakage reactance saturation Closed-slot IM saturation The origin of electromagnetic vibration by practical experience PM-assisted split-phase cage-rotor IM’s steady state The promise of renewable (hydro and wind) energy via cage-rotor and doubly fed variable speed generators e-transport propulsion and i-home appliances makes this third edition a state-of-the-art tool, conceived with numerous case studies and timely for both academia and industry.

Download or read book Reluctance Electric Machines written by Ion Boldea and published by CRC Press. This book was released on 2018-07-20 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric energy is arguably a key agent for our material prosperity. With the notable exception of photovoltaic generators, electric generators are exclusively used to produce electric energy from mechanical energy. More than 60% of all electric energy is used in electric motors for useful mechanical work in various industries. This book presents the modeling, performance, design, and control of reluctance synchronous and flux-modulation machines developed for higher efficiency and lower cost. It covers one- and three-phase reluctance synchronous motors in line-start applications and various reluctance flux-modulation motors in pulse width modulation converter-fed variable speed drives. FEATURES Presents basic and up-to-date knowledge about the topologies, modeling, performance, design, and control of reluctance synchronous machines. Includes information on recently introduced reluctance flux-modulation electric machines (switched- flux, flux-reversal, Vernier, transverse flux, claw pole, magnetic-geared dual-rotor, brushless doubly fed, etc.). Features numerous examples and case studies throughout. Provides a comprehensive overview of all reluctance electric machines.

Download or read book Basic Electrical and Instrumentation Engineering written by P. Sivaraman and published by John Wiley & Sons. This book was released on 2021-01-13 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical and instrumentation engineering is changing rapidly, and it is important for the veteran engineer in the field not only to have a valuable and reliable reference work which he or she can consult for basic concepts, but also to be up to date on any changes to basic equipment or processes that might have occurred in the field. Covering all of the basic concepts, from three-phase power supply and its various types of connection and conversion, to power equation and discussions of the protection of power system, to transformers, voltage regulation, and many other concepts, this volume is the one-stop, "go to" for all of the engineer's questions on basic electrical and instrumentation engineering. There are chapters covering the construction and working principle of the DC machine, all varieties of motors, fundamental concepts and operating principles of measuring, and instrumentation, both from a "high end" point of view and the point of view of developing countries, emphasizing low-cost methods. A valuable reference for engineers, scientists, chemists, and students, this volume is applicable to many different fields, across many different industries, at all levels. It is a must-have for any library.
