转速在直流电机运行中起到重要的作用,如何更好地测量出电机的转速,做好对电机的调速工作具有重要的意义和作用,电机在运行的过程中具有很好的性能,当前的电机调速性能比较严格,而且使用了直流调速系统。本文详细分析了电动机的转速系统,电动机的硬件系统主要是:控制驱动,测试以及硬件电路;软件设计采用C语言编程。该系统使用脉冲的方式有利于电动机的启动,而且可以调节脉冲宽度,通过光电开关可以更好的测量电动机的转速,在液晶显示屏上可以对电机的转速进行显示,最终实现对电动机转速进行控制的目的,可以对出现的问题进行分析。
The speed plays an important role in the operation of the DC motor. How to measure the speed of the motor better and has a great significance and effect on the speed regulation of the motor, the motor has good performance in the running process, The motor speed performance more stringent, and the use of a DC speed control system. This paper analyzes in detail the motor speed system, the motor hardware system is mainly: control drive, test and hardware circuits; software design using C language programming. The system uses the pulse mode is conducive to the motor start, but also to adjust the pulse width, the photoelectric switch can better measure the motor speed, the liquid crystal display can display the motor speed, the final realization of the motor speed control The purpose of the problem can be analyzed.
