Rotating machines: principles and construction

In parallel with this diversification in terms of applications, the field of technical solutions exploitable in electromechanical energy conversion has been significantly enriched. Progress in the field of power electronics has clearly been a determining factor in the development of electromechanical structures that are increasingly flexible and efficient in meeting target specifications (speed variation, energy reversibility management, etc.). While these advances initially concerned conventional, magnetic-effect structures, the development of new materials with enhanced performance and functionality (composite magnetic materials, superconductors, "electroactive" materials such as piezoelectric ceramics and magnetostrictive alloys, etc.) has led to a significant broadening of the very principles on which energy conversion can take place.

In view of its widespread predominance, the family of rotating machines based on magnetic field interaction is the subject of a specific study: on the basis of an original analytical approach, the elementary principles classically used are studied and characterized. In view of the technical aspects underlying the design of the structures considered, some data and trends relating to the main families of materials used are then proposed, before finally addressing the methodological aspects linked to the optimal dimensioning of a structure satisfying a given set of specifications and criteria.

The article "Rotating electrical machines. Electromechanical energy conversion" is the subject of two booklets:

D 3410 Rotating machines: electromechanical energy conversion

D 3411 Rotating machines: principles and construction

The subjects are not independent of each other.

Readers will need to refer to the other booklet often enough.
