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 asMagnetic, electric, and insulation materialsElectric windings and their mmfMagnetization curve and inductanceLeakage inductances and resistancesSteady-state equivalent circuit and performanceStarting and speed control methodsSkin and on-load saturation effectsField harmonics, parasitic torques, radial forces, noiseLossesThermal modelingSingle-phase induction machine basicsSingle-phase induction motors: steady-state modeling and performanceFully revised and updated to reflect the last decade's progress in the field, this third edition adds new sections, such asMultiphase and multilayer tooth-wound coil windingsThe brushless doubly fed induction machine (BDFIM)Equivalent circuits for BDFIMControl principles for doubly fed IMMagnetic saturation effects on current and torque versus slip curvesRotor leakage reactance saturationClosed-slot IM saturationThe origin of electromagnetic vibration by practical experiencePM-assisted split-phase cage-rotor IM's steady stateThe 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.

The numerous numerical design and control examples(with practical specifications) throughout the 23 Chapters of the book allow the reader deep and fast access to a practical but thorough unitary (good for comparisons) methodology in designing and control of LEMs for various applications

The third edition of this bestselling textbook incorporates the latest technologies used to save energy and increase productivity, stability, and reliability. It includes new references to key research and development activities, adds nearly 120 new pages covering recent advances, and features two new chapters on advanced scalar control and multiphase electric machine drives. All solved numerical examples have been retained, and 10 MATLAB®¿Simulink® programs remain online to ensure students gain a practical understanding of the subtleties involved in the operation of modern electric drives.

Based on author Ion Boldea''s 40 years of experience and the latest research, Linear Electric Machines, Drives, and Maglevs Handbook provides a practical and comprehensive resource on the steady improvement in this field. The book presents in-depth reviews of basic concepts and detailed explorations of complex subjects, including classifications and practical topologies, with sample results based on an up-to-date survey of the field. Packed with case studies, this state-of-the-art handbook covers topics such as modeling, steady state, and transients as well as control, design, and testing of linear machines and drives. It includes discussion of types and applications-from small compressors for refrigerators to MAGLEV transportation-of linear electric machines. Additional topics include low and high speed linear induction or synchronous motors, with and without PMs, with progressive or oscillatory linear motion, from topologies through modeling, design, dynamics, and control. With a breadth and depth of coverage not found in currently available references, this book includes formulas and methods that make it an authoritative and comprehensive resource for use in R&D and testing of innovative solutions to new industrial challenges in linear electric motion/energy automatic control.
