Investigation of Rotor Dynamic and High-Speed Bearing Technology for a 3KW Turbo-Alternator.

摘要

The report presents the initial results of an analytical and test rig investigation to identify any limitations or problems relative to high-speed bearings and rotor dynamics for future,very small (3KW) turboalternators. The results reported cover the following three tasks:An analytical effort to select a representative 3KW turboalternator configuration in terms of the major aerodynamic and electrical rotating components;An analytical effort to determine shaft-assembly/bearing-system arrangements applicable to the 3KW turboalternator configuration; A detailed design and initial test of a full scale test rig representative of the optimum shaft-assembly/bearing-system arrangement for the 3KW turboalternator.
