Abstract

Un moteur basse vitesse à courant alternatif dont larbre moteur tourne à une vitesse denviron 300 tr/min est présenté et un tel moteur est utile dans diverses industries et différents dispositifs, comme des systèmes de forage à transmission supérieure. En raison de la basse vitesse de larbre, léquipement de réduction de vitesse mécanique peut être facultatif. De plus, larbre moteur peut être creux pour faciliter lécoulement de fluide, comme de la boue de forage.
