20090230804 | ROTOR ASSEMBLY FOR ELECTROMECHANICAL MACHINE - A rotor assembly for an electromechanical machine includes a rotor core, an outer sleeve and an inner sleeve. The rotor core includes an outer diameter, and the outer sleeve is positioned about the outer diameter. The inner sleeve is positioned between the rotor core and the outer sleeve. One of the outer sleeve and the inner sleeve dampens electromagnetic flux generated by the rotor assembly. | 09-17-2009 |
20130181568 | BRUSHLESS STARTER GENERATOR - A brushless starter generator includes a wound field generator having a rotor that includes a damper winding, wherein the damper winding includes a plurality of poles. Also included is at least one pole face disposed within each of the plurality of poles, wherein the at least one pole face comprises a slot opening. Further included is at least one damper bar relatively entirely filling the slot opening. | 07-18-2013 |
20140028141 | ROTOR AND GENERATOR FOR REDUCING HARMONICS - A rotor for a generator comprises a stack of laminate plates and conductive end caps on either side thereof. The laminate plates and the end caps have holes near a periphery thereof, and conductive rods are positioned in the holes, and secured to the end caps. The stack, the end caps and the rods are then skewed by a desired angle with respect to a centerline of the rotor. The resulting rotor core may then be mounted to a rotor shaft, and wound, with the windings also being skewed due to skewing of the core. The end caps and rods form a damper cage that aids in reducing harmonics. | 01-30-2014 |
20140103774 | WOUND-FIELD SYNCHRONOUS MACHINE INCLUDING ROTOR DAMPER-SLEEVE - A wound-field synchronous machine includes a stator and a rotor. Around the rotor is a rotor sleeve including a damper bar assembly forming an amortisseur circuit. | 04-17-2014 |
