Book excerpt: Excerpt from Moteurs a Collecteur a Courants AlternatifsEn 1890 et 1891, Gorges (Siemens et Halske) experimentait de son cote un moteur a collecteur tri-phase que represente la figure 1 et qui fonctionnait aussi bien comme moteur serie et comme moteur shunt. Sur ce moteur, on constata que, pour une position appropriee des balais, le facteur de puissance peut avoir pour valeur l'unite (compensation du decalage) et que, par un deplacement des balais vers l'avant ou vers l'arriere, on peut faire varier la vitesse dans de larges limites sans dissiper d'energie dans des resistances. Le fonctionnement du collecteur comme transformateur de frequence etait ainsi nettement mis en evidence.Les succes eclatants du moteur asynchrone polyphase, apparaissant en 1890 sous sa forme la plus simple avec l'induit en court-circuit, detournerent pendant un moment l'attention portee sur le moteur a collecteur: le collecteur et ses etincelles etaient consideres comme l'inconvenient inevitable des machines a courant continu, mais on desirait s'en debarrasser toutes les fois que cela etait possible. Cependant Ganz et C, Helios, Schneider et Cie Wagner et Cie, en Amerique, construisaient de petits moteurs d'ascenseurs monophases a collecteur de 1/8 a 20 chevaux; il en etait de meme de la Societe autrichienne Union qui exploitait une invention de Deri. La formation d'etincelles au collecteur creait de tres serieuses difficultes pour des moteurs plus puissants. Les moteurs mentionnes ci-dessus etaient etablis de facon a demarrer comme moteurs serie ou moteurs a repulsion et a fonctionner ensuite comme moteurs d'induction, le collecteur etant mis hors circuit. Il y a lieu de mentionner aussi le nom d'Atkinson en Angleterre: cet inventeur prit, en 1895 et 1898, toute une serie de brevets de moteurs a collecteur, et dans une conference faite aux Ingenieurs Civils en 1898, il a expose un certain nombre de vues tout a fait modernes.L'emploi de plus en plus repandu des moteurs asynchrones fit connaitre leurs defauts et le revers de la medaille.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Les Moteurs Électriques à Courant Continu Dans l'étude du fonctionnement des électromoteurs, pour les différentes conditions auxquelles ils sont soumis, j'ai essayé de montrer comment les choses se passent, plutôt que de tirer le résultat d'équations d'ailleurs faciles à établir. J 'ai voulu ainsi apprendre au lecteur à raison ner les cas qui peuvent se présenter et à. Ne pas accepter sans contrôle des résultats qui ne s'appliquent parfois qu'en apparence au cas spécial en cause. Le but que j'ai poursuivi expliquera et fera sans doute pardonner les répétitions qu'on trouvera dans cette partie de l'ouvrage.
