Imroving power density and torque density of synchronous machines

Yacine AMARA,

University of le Havre, France


This contribution discusses the degrees of freedom that could be advantageously exploited in the conception of synchronous machines in order to improve their power density and/or torque density. The aim is to inventory degrees of freedom identified in scientific and technical literatures. Identifying these additional degrees of freedom will help positively respond to highly constrained design problems, which are appearing due to the higher usage of electrical energy in many industrial and consumer products. The goal is also to stimulate new ideas in the design of synchronous machines.


Yacine Amara (S’00–M’03–SM’18) was born in Algiers, Algeria, in 1975. He received the Ingénieur d’Etat degree from the Ecole Nationale Polytechnique, Algiers, in 1997 and the Ph.D. degree in electri-cal and electronic engineering from the University of Paris South XI, Paris, France, in 2001. From 1998 to 2001, he worked toward the Ph.D. degree with the Laboratoire d’Electricité Signaux et Robot-ique (LESiR), Ecole Normale Supérieure de Cachan, Cachan, France. From 2003 to 2004, he was a Research Associate with the Department of Electronic and Electrical Engineering, University of Sheffield, Sheffield, U.K. From 2004 to 2007, he was a Lecturer with the Department of Electrical Engineering, Technical University of Belfort-Montbéliard, Belfort, France. Since 2008, he has been with the Groupe de Recherche en Electrotechnique et Automatique du Havre (GREAH), University of Le Havre, Le Havre, France, where is currently a Full Professor. His research interests include the design, modeling, and control of rotating and linear permanent-magnet machines for automotive and renewable energies applications.
