步进电动机和步进电动机驱动器构成步进电机驱动系统。步进电动机驱动系统的性能,不但取决于步进电动机自身的性能,也取决于步进电动机驱动器的优劣。对步进电动机驱动器的研究几乎是与步进电动机的研究同步进行的。
相信在日常生活中,大家都有接触过各种驱动器,那么,下面呢专业步进驱动器厂家“斯凯得”小编就来给大家科普下关于步进驱动器的相关知识。
步进电机驱动器有三种基本的步进电机驱动模式:整步、半步、细分、其主要区别在于电机线圈电流的控制密度(即激磁方式),下面专业步进驱动器厂家“斯凯得”小编就这三点详细说一说。
1、 整步驱动
在整步运行中,同一种步进电机即可配整/半步驱动器也可配细分驱动器,但运行效果不同。步进电机驱动器按脉冲/方向指令对两相步进电机的两个线圈循环激磁(即将线圈充电设定电流),这种驱动方式的每个脉冲将使电机移动一个基本步距角,即1.80度(标准两相电机的一圈共有200个步距角)
2、 半步驱动
在单相激磁时,电机转轴至整步位置上,驱动器收到下一脉冲后,如给另一相激磁且保持原来相继处在激磁状态,则电机转轴将移动半个步距角,停在相邻两个整步位置的中间。如此循环地对两相线圈进行单相然后双相激磁步进电机将以每个脉冲0.90度的半步方式转动。青蓝电机供应的所有的整/半步驱动器都可以执行整步和半步驱动,由驱动器拔码开关的拔位进行选择,和整步方式相比,半步方式具有精度高一倍和低速运行时振动较小的优点,所以实际使用整步/半步驱动器时一般选用半步模式。
3、 细分驱动
细分驱动模式具有低速振动极小和定位精度高两大优点。对于有时需要低速运行(即电机转轴有时工作在60rpm以下)或定位精度要求小于0.90度的步进应用中。其基本原理是对电机的两个线圈分别按正弦和余弦形的台阶进行精密电流控制,从而使得一个步距角的距离分成若干个细分步完成。例如十六细分的驱动方式可使每圈200标准步的步进电机达到每圈200*16=3200步的运行精度(即0.1125°)
专业步进驱动器厂家“斯凯得”专业技术人员总结:在整步运行下,每输入一个脉冲,电机轴的角位移是一个步距角,在半步运行状态下,每输入一个脉冲,电机轴的角位移是半个步距角。步进电机最好不使用整步状态,整步状态时振动相对大。
