Study on High Frequency Electromagnetic Vibration Suppression of Marine Generator

The research aims to reduce the acceleration of the bottom vibration of marine generators, with a focus on analyzing and studying the high-frequency electromagnetic vibration caused by the interaction between the stator and rotor harmonic magnetic fields. Suppression measures are proposed, and intermediate and principle prototype tests are conducted for verification. The results show that by optimizing the structure of the generator base and using damping components reasonably, high-frequency electromagnetic vibration can be effectively suppressed. The vibration acceleration value of the prototype at the characteristic frequency of the first-order tooth harmonic is 104.5dB, which is more than lOdB lower than that of the conventional structure marine generator.
