摘要
分析了次谐波引起的定子的磁振动,用有限元法计算了定予铁芯的固有频率,并讨论了边界条件对自振特性的影响。
In this paper, the magnetic vibration of stator caused by subharmonics is analyzed, natural freguency of stator core is calculated by finite elemental method. And the effect of boundary condition on the behaviour of free vibration of stator is discussed.
