  • 2. Udgave
  • Vital Source searchable e-book (Fixed pages)
  • Udgiver: Cengage Learning (Januar 2018)
  • ISBN: 9781337678353
Master the basic topics and fundamental concepts underlying electric machines, power electronics, and electric drives with FUNDAMENTALS OF ELECTRIC DRIVES, 2nd Edition. While other books on electric drives concentrate on converters and waveform analysis and ignore mechanical load dynamics or emphasize motor characteristics with little analysis of converters and controllers, this unique approach provides a complete overview of the subject at a level that’s ideal for full comprehension. You follow the analysis and design of a complete electric drive system with coverage of mechanical loads, motors, converters, sensing, and controllers. The author clearly presents drive applications to electric traction, robotics, and wind energy using real examples from industry throughout. With its practical content, this book even serves as a useful reference for professional electric drive engineers.

Trykt eller digital bog?

Ud over trykte bøger tilbyder vi tre forskellige typer af digitale bøger:

 

Vital Source Bookshelf: En velfungerende ebogsplatform, hvor bogen downloades til din computer og/eller mobile enhed.

 

Du skal bruge den gratis Bookshelf software til at læse læse bøgerne - der er indbygget gode værktøjer til f.eks. søgning, overstregning, notetagning mv. I langt de fleste tilfælde vil du samtidig have en sideløbende 1825 dages online adgang. Læs mere om Vital Source bøger

 

Levering: I forbindelse med købet opretter du et login. Når du har installeret Bookshelf softwaren, logger du blot ind og din bog downloades automatisk.

 

 

Adobe ebog: Dette er Adobe DRM ebøger som downloades til din lokale computer eller mobil enhed.

 

For at læse bøgerne kræves særlig software, som understøtter denne type. Softwaren er gratis, men du bør sikre at du har rettigheder til installere software på den maskine du påtænker at anvende den på. Læs mere om Adobe DRM bøger

 

Levering: Et download link sendes pr email umiddelbart efter købet.

 


Ibog: Dette er en online bog som kan læses på udgiverens website. 

Der kræves ikke særlig software, bogen læses i en almindelig browser.

 

Levering: Vores medarbejder sender dig en adgangsnøgle pr email.

 

Vi gør opmærksom på at der ikke er retur/fortrydelsesret på digitale varer.
