ELECTRIC MOTOR PROVIDING BEARING-FORCE UNLOADING
WARF: P230289US01

Inventors: Eric Severson, Nathan Petersen


The Invention

UW-Madison researchers have developed a hybrid electric machine bearing system that uses both gas and electromagnetic shaft support. The windings of the electric motor are used to reduce the loading of noncontact bearings through the application of an offsetting radial force. For aerodynamic gas bearings, this force may be converted to a torque force after sustaining levitation speeds have been obtained.
