In this thesis, the concept of mass imbalance in rotors is first fully defined. Then, the reasons for the occurrence of mass imbalance in rotor motors operating under different working conditions are examined, followed by an exploration of the consequences arising from it. Subsequently, the types of mass imbalance (static, coupled, and dynamic) are thoroughly explained.
Once the mass imbalance is completely described, the next step is to have the necessary knowledge and skills to address this issue. For this reason, various methods for achieving mass balance in rotors are outlined so that the best decision can be made to resolve this problem under different conditions.
When examining the methods for balancing mass, it is important to be able to apply them. Therefore, several cases of motors that have experienced mass imbalance are investigated, starting with how to diagnose the presence of mass imbalance, followed by how to analyze this imbalance and perform the related calculations. Finally, a simulation and design are conducted in a Simulink environment that demonstrates the mass imbalance in the rotor. Subsequently, this mass imbalance is eliminated through design, resulting in vibration levels being reduced to zero.
