电磁驱动磁悬浮进给机构研究

Study on the Magnetic Suspension Feeder Using Electromagnetism Driving

设计了一种新型电磁驱动磁悬浮进给机构,将电磁铁与导磁体静平衡位置交错,使其不仅产生悬浮力,而且还可利用此交错位置产生的复原力为驱动力,简化了结构设计与控制环节。分析了磁悬浮吸力及驱动力,在保证驱动力为最大的前提下,确定出电磁铁初始位置,并通过优化计算,给出了只与工作台质量有关而与其几何尺寸无关的电磁铁结构参数。

A new magnetic suspension feeder driven by electromagnetism is built. Staggering electromagnets and magnetizers at the balanceable position, the feeder generates not only a suspending power but also a recovering power, which can drive the magnetic table to move, thus the design and control of the feeder are simplified. The suspending power and the driving power are analyzed. To ensure the maximum driving power, the electromagnets of the original position and its structural parameters are calculated by optimization calculation, and the parameters are only concerned to the quality of the table but not to the geometrical dimensions.
