Overview
ABSTRACT
The considerable advances achieved in the field of electrotechnical materials such as permanent magnets and in that of power electronics have led to significant improvements and the development of new technologies for rotating electrical machines. These advances have notably allowed for the development of high-torque drives by means of permanent magnet machines. these technologies have found a privileged application field in naval electric propulsion and on-board actuators.

INTRODUCTION
Major advances in electrotechnical materials such as permanent magnets, and in power electronics, have led to significant improvements and the emergence of new technologies for rotating electrical machines. In particular, these advances have made it possible to produce compact, high-torque drives using permanent magnet machines. These technologies are particularly well-suited to naval electric propulsion and on-board actuators, for which the constraints of volume, availability and acoustic discretion are particularly demanding. Numerous developments aimed at using this type of machine in wind energy are currently underway.
