Available in PDF, EPUB and Kindle. Book excerpt: AC Synchronous Motors range in size from sub-fractional horsepower to over 10,000 horsepower. Smaller synchronous motors can be found in household devices such as clocks, timers, fans and cassette players, and as stepper motors in computer disk drives and printers. Larger synchronous motors are used in process industries and drive equipment such as compressors. Large synchronous motors most commonly employ a three-phase system. The smaller AC Synchronous Motors commonly use a single-phase system. Synchronous motor is consists of two parts those are stator and rotor. Stator is stationary part that produces rotating magnetic field and then, the rotor locks into step with rotating magnetic field. This paper focuses on uses the permanent magnet on rotor shaft to produce magnetic field instead of uses slip rings and carbon brush to supply external dc source to the shaft. Permanent magnet synchronous motor is also called brushless because the excitation flux is produced by permanent magnet. Application of neodymium-iron-boron (Nd2Fe14B) and samarium cobalt (Sm1Co5 and Sm2Co17) rare earth magnets results in high torque and power density, efficiency, and controllability, reliability, and ruggedness. The synchronous motor has the same physical stator as induction motor. Then the output of two type of motor can be analyse and compared the result. The output that should be considered is frequency, rpm, torque, hp, losses, and efficiency. From this project we can use the spec of induction motor to guide in design basic principal of synchronous motor with the same spec. Through of this some of development should be done to improve the efficiency and reliability of the motor.

Download or read book Permanent Magnet Motor Technology written by Jacek F. Gieras and published by CRC Press. This book was released on 2009-08-25 with total page 591 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of permanent magnet (PM) motor technology and its impact on electromechanical drives has grown exponentially since the publication of the bestselling second edition. The PM brushless motor market has grown considerably faster than the overall motion control market. This rapid growth makes it essential for electrical and electromechanical engineers and students to stay up-to-date on developments in modern electrical motors and drives, including their control, simulation, and CAD. Reflecting innovations in the development of PM motors for electromechanical drives, Permanent Magnet Motor Technology: Design and Applications, Third Edition demonstrates the construction of PM motor drives and supplies ready-to-implement solutions to common roadblocks along the way. This edition supplies fundamental equations and calculations for determining and evaluating system performance, efficiency, reliability, and cost. It explores modern computer-aided design of PM motors, including the finite element approach, and explains how to select PM motors to meet the specific requirements of electrical drives. The numerous examples, models, and diagrams provided in each chapter facilitate a lucid understanding of motor operations and characteristics. This 3rd edition of a bestselling reference has been thoroughly revised to include: Chapters on high speed motors and micromotors Advances in permanent magnet motor technology Additional numerical examples and illustrations An increased effort to bridge the gap between theory and industrial applications Modified research results The growing global trend toward energy conservation makes it quite possible that the era of the PM brushless motor drive is just around the corner. This reference book will give engineers, researchers, and graduate-level students the comprehensive understanding required to develop the breakthroughs that will push this exciting technology to the forefront.

Download or read book Electric Motors and Drives written by Austin Hughes and published by Elsevier. This book was released on 2013-10-22 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written for non-specialist users of electric motors and drives, this book explains how electric drives work and compares the performance of the main systems, with many examples of applications. The author's approach - using a minimum of mathematics - has made this book equally popular as an outline for professionals and an introductory student text. * First edition (1990) has sold over 6000 copies. Drives and Controls on the first edition: 'This book is very readable, up-to-date and should be extremely useful to both users and o.e.m. designers. I unhesitatingly recommend it to any busy engineer who needs to make informed judgements about selecting the right drive system.' New features of the second edition: * New section on the cycloconverter drive. * More on switched relectance motor drives. * More on vector-controlled induction motor drives. * More on power switching devices. * New 'question and answer' sections on common problems and misconceptions. * Updating throughout. Electric Motors and Drives is for non-specialist users of electric motors and drives. It fills the gap between specialist textbooks (which are pitched at a level which is too academic for the average user) and the more prosaic 'handbooks' which are filled with useful detail but provide little opportunity for the development of any real insight or understanding. The book explores most of the widely-used modern types of motor and drive, including conventional and brushless d.c., induction motors (mains and inverter-fed), stepping motors, synchronous motors (mains and converter-fed) and reluctance motors.

Download or read book Induction Motors written by Raúl Gregor and published by BoD – Books on Demand. This book was released on 2015-11-18 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: AC motors play a major role in modern industrial applications. Squirrel-cage induction motors (SCIMs) are probably the most frequently used when compared to other AC motors because of their low cost, ruggedness, and low maintenance. The material presented in this book is organized into four sections, covering the applications and structural properties of induction motors (IMs), fault detection and diagnostics, control strategies, and the more recently developed topology based on the multiphase (more than three phases) induction motors. This material should be of specific interest to engineers and researchers who are engaged in the modeling, design, and implementation of control algorithms applied to induction motors and, more generally, to readers broadly interested in nonlinear control, health condition monitoring, and fault diagnosis.
