Dynamic Modeling of the Stator Core of the Electrical Machine Using Anisotropic Characteristics

이방성을 고려한 회전기기 고정자 코어의 동적 모델링

The state core of a motor/generator was modeled using dynamic model updating technique based on the modal testing work. In order to take into account the orthotropic effect of laminated structure the axial, radial and circumferential properties of the solid element were separately varied to match the primary modes of the stator core which were extracted from the modal testing. Comparison of the results after model tuning showed fairly good coincidence with measured data.
