| 摘 要： | 采用一种先进的前处理技术，实现了在整域中利用二维有限元法计算不饱和情况下由于水轮发电机转子偏心造成的作用于转子上的不平衡磁拉力（即单边磁拉力），使不同偏心下计算出的磁拉力具有可比性．给出了单边磁拉力随偏心的不同而发生变化的规律，讨论了同一偏心下，激磁发生变化后单边磁拉力的变化情况．

| Abstract: | The unbalanced magnetic pull (UMP) caused by rotor eccentricity in hydrogenerator underunsaturated condition is studied by using an advanced pre-processing technique and 2D-FEM in thewhole calculating region. The relationship between the UMP and the exciting current under a rotor eccentricity is discussed, and the relationship between the UMP and the eccentricity is given. |
