Design and manufacturing elements for small motors
Petits moteurs électriques

The design of small motors has long drawn on more than a hundred years of accumulated experience in electrical engineering. The classic concepts of DC, synchronous and asynchronous motors have been the subject of a great deal of theoretical, simulation and experimental work. On the other hand, many small, economical motors have often been designed very rustically and empirically. Today's concern to improve the efficiency of small motors, and the need to reduce noise and vibration in many types of equipment, has led manufacturers to implement increasingly powerful design aids incorporating electromagnetic finite element calculation codes [23][24][25] . Finally, expert systems are currently being developed to aid the design of small...
