摘要
介绍一种基于89C51单片机的步进马达寿命测试仪的设计。它采用8254可编程定时器/计数器来实现1Hz～2kHz步进式脉冲输出,并使用A3967SLB二相步进电机驱动器驱动。具有低成本、高分辨率、反应速度快、性能稳定和硬件结构简单等优点。
This paper describes a kind of Steeping Motor Life Tester using 89C51 microcomputer.8254 Programmable timer/ counter is used to output steeping pulse range from one to two thousand Hz,and A3967SLB,a two phase steeping motor drive chip is used as a driver.The tester has so many advantages such as low cost,high resolution,quick response,steady quality,simple hardware composition and so on.
