Electric Drive - Design Methodology

Informationen zum Autor Marcel Jufer is Emeritus Professor at the Swiss Federal Institute of Technology, Lausanne, Switzerland. Klappentext Electric Drives: Design Methodology An electric drive that is designed or adapted to a specific application must take into account all the elements of the chain of constituent elements in its use and deployment. In addition to the motor, the transmission, power electronics, control, sensors, and electrical protection systems must be taken into account. The motor and the transmission can be optimized and designed to obtain the best energy efficiency assessment, in particular for dynamic nodes. An inventory and a characterization of these various components is proposed as part of this book's examination and explanation of the different technology elements, as well as a dynamic model of the system, with the whole system constituting a methodology for integrated electric drive design. Zusammenfassung An electric drive that is designed or adapted to a specificapplication must take into account all the elements of the chain ofconstituent elements in its use and deployment. In addition to themotor, the transmission, power electronics, control, sensors, andelectrical protection systems must be taken into account. Inhaltsverzeichnis Chapter 1.
