  • Top drive drilling system and other applications using a low speed direct drive AC motor
    Patent number: 8047306
    Abstract: 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.
    Type: Grant
    Filed: February 25, 2009
    Date of Patent: November 1, 2011
    Assignee: LeTourneau Technologies Drilling Systems, Inc.
    Inventors: Kevin R Williams, Alvie E. Howard, Jr., Daniel F. McNease, Rudy Harris, Richard Bradley
