誘導モータの磁場・振動連成解析

抄録

Due to the increasing demand for electric motors in recent years, the vibration analysis of electric motors is becoming more important. However, the spatio-temporal distribution of the electromagnetic excitation force generated inside the motor is complicated. Moreover, it is difficult to describe the elastic mechanical characteristics of the motor made of composite material. Therefore, it is difficult to predict the vibration of the motor with high accuracy. With the purpose of establishing a high-precision vibration analysis technology for induction motors, we established a magnetic field analysis model and a structural analysis model for the coupled analysis of magnetic field and vibration. The frequency response analysis was performed by coupling these models, and its validity is discussed.
