Flux-Based Deadbeat Control of Induction-Motor Torque

NASA Tech Briefs, April 2003 cones at the time of initial contact. For this purpose, the mating surfaces of the drive cones are coated with dry lubricant films. In addition, the ball-bearing assembly contains a reservoir designed to dispense lubricant to support an elastohydrodynamic film for the specified lifetime of the system. This work was done by Edward P. Kingsbury, Robert Price, Erik Gelotte, and Herbert B. Singer of The Bearing Consultants, LLP for Glenn Research Center.
