Electric Machines: Steady State and Performance with MATLAB pdf

Ion Gheorghe Boldia (nacido el 7 de enero de 1945) es profesor emérito de la Universidad Politehnica Timisoara, Rumania. Ion Boldea ha introducido muchas novedades en tecnología de máquinas eléctricas para mejorar la productividad industrial, ahorrar energía y reducir la contaminación del aire. Desarrolló un factor de bondad óptimo para diseñar motores de inducción lineales de alta velocidad para abordar factores como las vibraciones mecánicas y la flexión. Presentó el Magnibus-01, un vehículo de prueba de levitación magnética de 4 toneladas con motores síncronos homopolares lineales para propulsión y levitación magnéticas integradas con guías pasivas. El concepto de flujo activo del Dr. Boldea es una fuerza unificadora para simplificar el control sin sensores de los accionamientos de motores de CA que se ha implementado en muchas aplicaciones industriales. Su trabajo en el control del vector de par se ha convertido en un estándar industrial para accionamientos de motores eléctricos.

Electric Machines: Steady State and Performance with MATLAB pdf por ion boldea

With its comprehensive coverage of the state of the art, this Second Edition introduces basic types of transformers and electric machines. Classifications and characterization―modeling and performance―of power electric transformers (single and multiphase), motors and generators, commercial machines (dc brush, induction dc excited synchronous, PM synchronous, reluctance synchronous) and some new ones (multiphase ac machines, switched reluctance machines) with great potential for industry with rotary or linear motion are all treated in the book. The book covers, in detail, circuit modeling characteristics and performance characteristics under steady state, testing techniques and preliminary electromagnetic-thermic dimensioning with lots of solved numerical examples and special cases to illustrate new electric machines with strong industrialization potential. All formulae used to characterize parameters and performance may be safely used in industry for preliminary designs and have been applied in the book through numerical solved examples of industrial interest. Numerous computer simulation programs in MATLAB® and Simulink® that illustrate performance characteristics present in the chapters are included and many be used as homework to facilitate a deeper understanding of fundamental issues. This book is intended for a first-semester course covering electric transformers, rotary and linear machines, steady-state modeling and performance computation, preliminary dimensioning, and testing standardized and innovative techniques. The textbook may be used by R&D engineers in industry as all machine parameters and characteristics are calculated by ready-to-use industrial design mathematical expressions.
