Electrical Machines & their Applications, Volume 1

Electrical systems transfer electricity which is mostly produced and consumed by rotating electrical machines. Further, the use of electric and hybrid electric drivelines in both passenger and heavy vehicles is now commonplace and with a continuously growing market share.

Electrical machines and electric drives are therefore a vital part of the future electrical ecosystem in the global quest towards solutions to environmental challenges. In the electrical machine and drive research group, we are analysing and developing novel concepts and technologies aimed at enabling energy savings and cost reductions in the field of electric machinery and electric drives including their control. We are collaborating with a wide range of industrial and academic actors and are always interested in establishing new, collaborative research initiatives.

The activities encompass design and analysis of novel electric machinery and electric drives for traction applications as well as corresponding auxiliaries.

In recent years, focus has been put on modular converter and machine concepts in order to realize compact integrated electric drives. Further, design of electric machinery taking production aspects into account and the interaction between battery systems and power electronic loads are presently being investigated.

Within the field of electric drives used in industrial applications, activities within the group include development of new control algorithms for control of electric drives, design and analysis of high-speed electric machinery used in industrial hand tools and the analysis of collaborative networks of electric machinery used in larger industrial plants.

Definition: The rate at which the work is being done in an electrical circuit is called an electric power. In other words, the electric power is defined as the rate of the transferred of energy. The electric power is produced by the generator and can also be supplied by the electrical batteries. It gives a low entropy form of energy which is carried over long distance and also it is converted into various other forms of energy like motion, heat energy, etc.

Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit.

Такая архитектура стала популярной в те времена, когда церкви одновременно служили и крепостями, защищавшими от вторжения мавров, поскольку одну дверь легче забаррикадировать. Теперь у нее была другая функция: любой турист, входящий в собор, должен купить билет. Дверь высотой в шесть метров закрылась с гулким стуком, и Беккер оказался заперт в Божьем доме. Он закрыл глаза и постарался сползти на скамье как можно ниже: он единственный в церкви был не в черном. Откуда-то донеслись звуки песнопения. В задней части церкви между скамьями продвигался человек, стараясь держаться в тени. Ему удалось проскользнуть внутрь в последнюю секунду перед тем, как дверь закрылась.

Electrical Machines and Drives

Там, где только что было его плечо, оказалась черная пустота. Она шагнула вперед, но и там была та же пустота. Сигналы продолжались.

Час сорок пять ночи. Он в недоумении посмотрел на двухцветного. - Ты сказал - в два ночи. Панк кивнул и расхохотался. - Похоже, ты облажался, приятель.

Стратмор вздохнул. - Оставь эти штучки детям, Грег. Отпусти. - Чтобы вы меня убили.

 Потому что Стратмор обошел систему Сквозь строй? - Фонтейн опустил глаза на компьютерную распечатку. - Да, - сказала.  - Кроме того, ТРАНСТЕКСТ уже больше двадцати часов не может справиться с каким-то файлом.

 Хочешь со мной переспать? - Теперь на Беккера смотрела юная девица, похожая на персонаж фильма ужасов Рассвет мертвецов. Темнота коридора перетекла в просторное цементное помещение, пропитанное запахом пота и алкоголя, и Беккеру открылась абсолютно сюрреалистическая картина: в глубокой пещере двигались, слившись в сплошную массу, сотни человеческих тел. Они наклонялись и распрямлялись, прижав руки к бокам, а их головы при этом раскачивались, как безжизненные шары, едва прикрепленные к негнущимся спинам.

Наверняка сегодня к ним поступил только один канадец со сломанным запястьем и сотрясением мозга, и его карточку нетрудно будет найти. Беккер понимал, что в больнице не захотят назвать имя и адрес больного незнакомому человеку, но он хорошо подготовился к разговору. В трубке раздались длинные гудки.

Беккер отшвырнул пистолет и без сил опустился на ступеньку. Впервые за целую вечность он почувствовал, что глаза его застилают слезы, и зажмурился, прогоняя влажную пелену. Он знал, что для эмоций еще будет время, а теперь пора отправляться домой.
