A low speed alternating current motor having motor shaft speeds of about (300) is provided, and such motor has application in numerous industries and devices, such as, for example, in top drive drilling systems. Because of the low shaft speed, mechanical speed reduction equipment may not be necessary. In addition, the motor shaft may be hollow to facilitate the flow of fluid, such as, for example, drilling mud.
Moteur à courant alternatif à rotation lente dont l~arbre possède une vitesse de rotation d~environ 300 tours/min. Ce moteur trouve une application dans de nombreuses industries et dispositifs, notamment dans des systèmes de forage à transmission supérieure. Il ne nécessite pas de mécanismes réducteurs de vitesse du fait de la faible vitesse de rotation de son arbre. L~arbre du moteur peut également être creux pour faciliter l~écoulement d~un fluide, notamment de boues de forage.
