摘要
本文介绍了电机的测速及显示原理。主要论述了一种不同于常用测速及显示技术的方法,它采用全数字电子计数测频法测速、使用4位7段数码管显示转速,具有编程实现容易、单片实现测速和显示等特点。
The paper introduces the theories of measuring and displaying motor speed. It mainly expounds on a particular method different from that of common speed measurement and display. It adopts a calibrating frequency method by full digital electric counting for speed measurement, and uses four digits through seven segments LED components to show speed. Furthermore, this method possesses some unique characteristics such as easy programming, high integration implementing speed measurement and display on a single chip, and so on.
