Overview
ABSTRACT
In practice, electric machines must embody a number of features: low mechanical inertia, rapid acceleration for a short start-up time, an immediately available large torque on the shaft, long thermal time constant and high reliability. The optimal solutions corresponding to these constraints most often lead to contradictory technological designs for very diverse applications in industry, climatic engineering etc.

INTRODUCTION
This dossier is devoted to the practical realization of permanent magnet electric actuators with commutators (mechanical or electronic) as they are currently marketed. It has been produced in part thanks to documents kindly supplied to us by various European manufacturers.
A brief overview of the wide variety of applications for this type of actuator is given at the end.
We won't go into how they work or how they are managed, as these are described in detail in the
