DEVELOPMENT AND APPLICATION OF A VERTICAL HIGH SPEED MOTOR-COMPRESSOR SIMULATOR FOR ROTOR DROP ONTO AUXILIARY BEARINGS

摘要

During the conceptual development of a subsea motor-compressor prototype running on active magnetic bearings, the emergency landing on the catcher bearings was identified as a potential technology gap. This is because the rotor in object is vertical and supercritical. A subscale simulator was then developed with the twofold aim to collect useful experimental data for data matching with a numerical simulation (also developed for this special application) and to perform endurance testing of the catcher bearings to understand their mechanical limits.
