Analyzing Tangential Force of Electromagnetic Loading on High Speed Motorized Spindle

  • 摘要: 非接触电磁加载实现了高速电主轴的动态加载。在动态加载过程中,由于实心加载盘的高速旋转,其内部产生的涡流以及集肤效应会对电磁铁产生的磁场造成影响,而且随着转速的提高,影响更加明显,会导致径向力逐渐减小,并且产生切向力。本文旨在研究电主轴在动态加载时切向力在不同条件下的变化关系,主要利用解析法与有限元法分析计算加载过程中的切向力,其计算结果较吻合。通过分析不同条件下的动态加载过程,发现切向力的变化具有一定规律,切向力会随着转速、电流以及气隙的变化而产生增加或减小的趋势,最终得出了切向力的加载特性规律。
