Linear Synchronous Motors by Jacek F. Gieras,Zbigniew J. Piech,Bronislaw Tomczuk Pdf

Contrary to some opinions, electric motors are decidedly not part of an old-fashioned area of research. They are, in fact, the most popular machines of everyday life, and the number of types increase almost every year. Advances in materials engineering, power electronics, and control strategies along with energy and reliability demands continue to stimulate the development of exciting new technologies and applications. Ranking high among the most exciting of these technologies are linear synchronous motors (LSMs). Linear Synchronous Motors: Transportation and Automation Systems provides a comprehensive treatment of all types of brushless LSMs-their construction, electromagnetic effects, control, and applications. It explains the physics of hard magnetic materials, discusses permanent magnet and superconducting excitation systems, and addresses applications in factory automation and high-speed transportation systems. LSMs have better performance and higher power density than their induction counterparts, and they can operate with a larger mechanical clearance between their stationary and moving parts. Paying equal attention to the design and the applications of LSMs, Linear Synchronous Motors offers a unique opportunity to master the inner workings of LSMs, discover new research results, and keep abreast of their emerging applications. Electromechanical designers, electrical and mechanical engineers, as well as linear motor enthusiasts will welcome this broad and authoritative work to their reference collections.

Advanced Direct Thrust Force Control of Linear Permanent Magnet Synchronous Motor by Muhammad Ali Masood Cheema,John Edward Fletcher Pdf

This book explores the direct thrust force control (DTFC) of tubular surface-mount linear permanent magnet synchronous motors (linear PMSMs). It presents a detailed account and analysis of several advanced nonlinear control schemes, based on the direct thrust control principle, to achieve a reduction in steady-state ripple in thrust force with faster transient response, and describes their experimental validation. It also provides rigorous details of the dynamic modelling of linear PMSMs from a control system perspective, and demonstrates the superior control performance of the proposed techniques compared to the current state-of-the-art techniques. Lastly, the book proposes and validates a stator flux observer for sensorless speed estimation comprising a linear state observer and an improved sliding mode component.

Control of Non-conventional Synchronous Motors by Jean-Paul Louis Pdf

Classical synchronous motors are the most effective device to drive industrial production systems and robots with precision and rapidity. However, numerous applications require efficient controls in non-conventional situations. Firstly, this is the case with synchronous motors supplied by thyristor line-commutated inverters, or with synchronous motors with faults on one or several phases. Secondly, many drive systems use non-conventional motors such as polyphase (more than three phases) synchronous motors, synchronous motors with double excitation, permanent magnet linear synchronous motors, synchronous and switched reluctance motors, stepping motors and piezoelectric motors. This book presents efficient controls to improve the use of these non-conventional motors. Contents 1. Self-controlled Synchronous Motor: Principles of Function and Simplified Control Model, Francis Labrique and François Baudart. 2. Self-controlled Synchronous Motor: Dynamic Model Including the Behavior of Damper Windings and Commutation Overlap, Ernest Matagne. 3. Synchronous Machines in Degraded Mode, Damien Flieller, Ngac Ky Nguyen, Hervé Schwab and Guy Sturtzer. 4. Control of the Double-star Synchronous Machine Supplied by PWM Inverters, Mohamed Fouad Benkhoris. 5. Vectorial Modeling and Control of Multiphase Machines with Non-salient Poles Supplied by an Inverter, Xavier Kestelyn and Éric Semail. 6. Hybrid Excitation Synchronous Machines, Nicolas Patin and Lionel Vido. 7. Advanced Control of the Linear Synchronous Motor, Ghislain Remy and Pierre-Jean Barre. 8. Variable Reluctance Machines: Modeling and Control, Mickael Hilairet, Thierry Lubin and Abdelmounaïm Tounzi. 9. Control of the Stepping Motor, Bruno Robert and Moez Feki . 10. Control of Piezoelectric Actuators, Frédéric Giraud and Betty Lemaire-Semail.

Permanent-Magnet DC Linear Motors by Amitava Basak Pdf

No standard work of reference, dealing with dc linear motor in all its aspects has ever been published. However, a considerable amount of literature in the form of published papers dealing with this subject, and also an amount of hitherto unpublished work, particularly of an industrial or applied nature, has been accumulated during the last 25 years. An attempt has been made to collate all this information and present it in a comprehensive and orderly manner in this unique volume. This book has been designed to be useful to two main categories of readers, namely, electrical and mechanical engineers in the user industries, and post-graduates and students embracing mechanical and electrical engineers.

Control of Permanent Magnet Synchronous Motors by Sadegh Vaez-Zadeh Pdf

Permanent magnet synchronous (PMS) motors stand at the forefront of electric motor development due to their energy saving capabilities and performance potential. The motors have been developed in response to mounting environmental crises and growing electricity prices, and they have enabled the emergence of motor drive applications like those found in electric and hybrid vehicles, fly by wire, and drones. Control of Permanent Magnet Synchronous Motors is a timely advancement along that path as the first comprehensive, self-contained, and thoroughly up-to-date book devoted solely to the control of PMS motors. It offers a deep and extended analysis, design, implementation, and performance evaluation of major motor control methods, including Vector, Direct Torque, Predictive, Deadbeat, and Combined Control, in a systematic and coherent manner. All major Sensorless Control and Parameter Estimation methods are also studied. The book places great emphasis on energy saving control schemes.
