Patent number: 7250699Abstract: The invention relates to the vibration damper systems (here, method and apparatus) for active removal of beyond-normal internal vibrations from turbine-generator-sets [T-G-Ss]. The invention relies on dynamic forces generated by at least a pair (when symmetrically placed) of “wings” or by at least one “wing” (when centrally placed), or combination of that, and associated hardware mounted on the bearing housing, which operate to offset internally produced vibrations in an active or “real time” fashion. This is in contrast to the typical method of taking the turbine-generator off-line, shutting it down and then eliminating the source of vibration. The invention allows the generator to remain operational during adjustments. Thus, it remains on-line producing electricity and associated revenue. The system may be installed at presently operating T-G-Ss. It also foresees the simple developments to be done in future designed T-G-Ss for use of this method.Type: GrantFiled: September 12, 2005Date of Patent: July 31, 2007Inventor: Vladilen V. Safonov

Patent number: 7250701Abstract: An end surface of a rotor core is offset from an end surface of a stator core by a predetermined amount in an axial direction going away from Hall ICs.
