study of rf direct bandpass sampling structure of software radio amp; amp; its use
射频直接带通采样软件无线电结构分析及其应用
although reducer can avoid step sense and oscillation partly, the strap transmission will influence orientation precision ( it is key norm to the small metallographic sample cutting machine ), so plan to use step motor to drive the screw directly, the step motor at low velocity, which is not drived by the subdividing drive system, will have obvious oscillation and noise that would influence the cutting function, the usage life and sample structure
由于步进电机是通过皮带轮减速来驱动丝杠，进而带动砂轮片前进和后退，虽然减速能部分消除步进感和振动，但皮带传动会影响定位精度，定位精度对精密切割机十分关键的技术指标。采用步进电机直接驱动丝杠，未经细分驱动的步进电机在低速运行时，有明显的步进感、振动和噪声，从而对切割的性能、砂轮片的使用寿命、试样的组织结构产生较大的影响。
