摘要
介绍一种电磁铁驱动的微进给机构及其控制电路设计。电磁铁本身具有输出力大、结构简单、成本低等特点。本文通过力的差动控制、施加预偏置电流、电流负反馈功率放大和比例—微分模拟校正，使其线性度好、响应灵敏。所构成的微进给机构可用作非圆曲面高速车削加工中的刀具进给装置。
This paper presents a microstroke mechanism driven by electromagnets and its control circuit design.Electromagnet has some nice features of itself, such as large force,simple structure,and low cost,etc. Through differential control of the output force,pre exciting current,power amplification with negative current feedback,and PD (proportional differential) anolog compensation,this mechanism driver by electromagnets has fine linearity and high reponsibility. So it is suitable for tool positioning in high speed non circular machine.
