  • 步进电机驱动器是一种将电脉冲转化为角位移的执行机构。当步进驱动器接收到一个脉冲信号,它就驱动步进电机按设定的方向转动一个固定的角度(称为“步距角”),它的旋转是以固定的角度一步一步运行的。可以通过控制脉冲个数来控制角位移量,从而达到准确定位的目的;同时可以通过控制脉冲频率来控制电机转动的速度和加速度,从而达到调速和定位的目的。广泛应用于雕刻机、水晶研磨机、中型数控机床、脑电绣花机、包装机械、喷泉、点胶机、切料送料系统等分辨率较高的大、中型数控设备上。
    步进电机的相数是指电机内部的线圈组数,常用的有二相、三相、四相、五相步进电机。 电机相数不同,其步距角也不同,一般二相电机的步距角为1.8度、三相为1.2度、五相的为0.72度。在没有细分驱动器时,用户主要靠选择不同相数的步 进电机来满足步距角的要求。如果使用细分驱动器,则相数将变得没有意义,用户只需在驱动器上改变细分数,就可以改变步距角。
    驱动器细分后将对电机的运行性能产生质的飞跃,但是这一切都是由驱动器本身产生的,和电机及控制系统无关。在使用时,用户唯一需要注意的一点是步进电机步距角的改变,这一点将对控制系统所发的步进信号的频率有影响,因为细分后步进电机的步距角将变小,要求步进信号的频率要相应提高。以1.8度步进电机为例:驱动器在半步状态时步距角为0.9度,而在十细分时步距角为0.18度,这样在要求电机转速相同的情况下,控制系统所发的步进信号的频率在十细分时为半步运行时的5倍。
    一般步进电机的精度为步进角的3~5%。步进电机单步的偏差并不会影响到下一步的精度,因此步进电机精度不累积。
