SIMOTICS electric motors for industry

Electric Motors and Drives is intended for non-specialist users of electric motors and drives, filling the gap between theory-based academic textbooks and the more prosaic 'handbooks', which provide useful detail but little opportunity for the development of real insight and understanding. The book explores all of the widely-used modern types of motor and drive, including conventional and brushless D. Austin Hughes' approach, using a minimum of maths, has established Electric Motors and Drives as a leading guide for engineers, and the key to a complex subject for a wider readership, including technicians, managers and students. Professional: Electrical and mechanical engineers and technicians requiring a working knowledge of motors and drives but not a mathematical or academic level of knowledge. Austin Hughes was a long-time member of the innovative motors and drives research team at the University of Leeds, UK, and has established a reputation for an informal style that opens up complex subjects to a wide readership, including students and managers as well as technicians and engineers. I unhesitatingly recommend it to any busy engineer who needs to make informed judgments about selecting the right drive system.

Characterization of electric motor drives for traction applications Abstract: The ideal characteristics of an electric motor drive for traction application in an electric and hybrid electric vehicle are high torque at low speed region for fast acceleration, hill climbing and obstacle negotiation, and low torque at high speed for normal driving. To minimize the power rating of the motor drive, therefore, the energy storage power rating, at the given vehicle performance, the electric motor drive is required to have a long constant power range to meet the torque and speed demand. In this paper, the effect of the motor characteristics on the vehicle performance is analyzed, and the characteristics of three major electric motors-induction motor, permanent magnet brushless DC motor and switched reluctance motor are investigated.

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. Austin Hughes was a long-time member of the innovative motors and drives research team at the University of Leeds, UK, and has established a reputation for an informal style that opens up complex subjects to a wide readership, including students and managers as well as technicians and engineers.

There has been significant innovation in this area since the fourth edition, particularly in the automotive, aircraft and industrial sectors, with novel motor topologies emerging, including hybrid designs that combine permanent magnet and reluctance effects.

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. Electric motors can be powered by direct current DC sources, such as from batteries, or rectifiers , or by alternating current AC sources, such as a power grid, inverters or electrical generators.

This fourth edition is again intended primarily for nonspecialist users or students of electric motors and drives. From the outset the aim has been to bridge 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 full of detailed information but provide little opportunity for the development of any real insight. We intend to continue what has been a successful formula by providing the reader with an understanding of how each motor and drive system works, in the belief that it is only by knowing what should happen and why that informed judgements and sound comparisons can be made. It identified several new topics needed to bring the work up to date, but these areas were not ones that the original author AH was equipped to address, having long since retired.

 У меня затекли плечи. Мидж не поддалась. - Прими аспирин. - Не помассируешь мне спину? - Он надулся. Мидж покачала головой. - В Космополитене пишут, что две трети просьб потереть спинку кончаются сексом. Бринкерхофф возмутился.

ГЛАВА 32 Дэвид Беккер остановился в коридоре у номера 301. Он знал, что где-то за этой витиеватой резной дверью находится кольцо. Вопрос национальной безопасности. За дверью послышалось движение, раздались голоса. Он постучал. Послышался голос с сильным немецким акцентом: - Ja. Беккер молчал.

Ее основная работа в последние три года заключалась в тонкой настройке самого секретного компьютера в мире: большая часть программ, обеспечивавших феноменальное быстродействие ТРАНСТЕКСТА, была ее творением. Шифр в миллион бит едва ли можно было назвать реалистичным сценарием. - Ладно, - процедил Стратмор.  - Итак, даже в самых экстремальных условиях самый длинный шифр продержался в ТРАНСТЕКСТЕ около трех часов. - Да.

Беккер держался своей легенды: - Я из севильской полиции. Росио угрожающе приблизилась. - Я знаю всех полицейских в этом городе. Они мои лучшие клиенты. Беккер чувствовал, как ее глаза буквально впиваются в. Он решил сменить тактику: - Я из специальной группы, занимающейся туристами. Отдайте кольцо, или мне придется отвести вас в участок и… - И что? - спросила она, подняв брови в притворном ужасе.

Подобно киноперсонажу, в честь которого он и получил свое прозвище, его тело представляло собой шар, лишенный всякой растительности. В качестве штатного ангела-хранителя компьютерных систем АН Б Джабба ходил по отделам, делал замечания, что-то налаживал и тем самым постоянно подтверждал свое кредо, гласившее, что профилактика-лучшее лекарство. Ни один из поднадзорных ему компьютеров АНБ не заразился вирусом, и он был намерен не допустить этого и впредь. Рабочим местом Джаббы была платформа, с которой открывался вид на подземную сверхсекретную базу данных АНБ. Именно здесь вирус мог бы причинить наибольший ущерб, и именно здесь Джабба проводил большую часть времени. Однако в данный момент у него был перерыв и он поглощал пирог с сыром и перцем в круглосуточной столовой АНБ.

Часовой пожал плечами. - С вами хочет поговорить начальник шифровалки. Она сейчас будет. - Она? - Беккер рассмеялся. Он не заметил в АНБ ни одного существа женского пола.

Такси приближалось, и свет его фар бросал на дорогу таинственные тени. Раздался еще один выстрел. Пуля попала в корпус мотоцикла и рикошетом отлетела в сторону. Беккер изо всех сил старался удержаться на шоссе, не дать веспе съехать на обочину. Я должен добраться до ангара.

    We cover the complete range of industrial motors — synchronous as well as asynchronous: from standard electric motors through servomotors for motion control applications up to high voltage and DC motors.
