Compliant stator
View Patent ↗A compliant stator motor is disclosed. In one implementation, the motor ( 200 ) includes a rotor ( 210 ), a stator ( 220 ) having main and auxiliary windings, an outer motor case ( 230 ), and a group of isolators ( 240 ) positioned between the stator ( 220 ) and outer motor case ( 230 ) to enhance forces applied to the foundation ( 260 ) due to excitation of the auxiliary windings. In another implementation, the motor ( 300 ) includes a rotor ( 310 ), a stator ( 320 ) including main and auxiliary windings, linear bearings ( 320 ) configured to constrain a motion of the stator ( 320 ) to an axial direction, and isolators ( 330 ) connected to the stator ( 320 ) and configured to enhance axial forces applied to the foundation due to excitation of the auxiliary windings.
