| 摘 要： | 大型直流电机在冶金企业中使用及为普遍。换向器的偏摆和凸片是造成该类电机运转中换向器表面产生电火的重花要原因之一。而目前有些厂使用的靠表法得不到准确的偏摆、凸片数据。 为此,本文提出了包括非接触电涡流传感器和TP—801微处理机在内的检测系统。该系统动态响应好、测量准确,并能满意地处理和记录测试数据。 检测系统由模拟检测和数据处理两部分组成。 本文介绍了该系统以及硬件和软件的原理,并对A/D转换速度加以简要讨论。

| Abstract: | Giant D. C. motor and generator are widely used in steel plants, but circular runout of their commutator often causes harmful electric spark. In order to solve this problem the amount of circular runout should be precisely detected and measured. However, it is dfficult to attain by conventional measuring method.In this paper, a new measuring system with a non-contacted edd-cur-rent transducer and a TP801 microprocessor is presented. It has good dynamic response and preciseness, data can be measured, processed and recorded simultaneously.The measuring system consists of two parts: analogue measuring and data processing. The function of the measuring system as well as the principle of software and hardware are discribed. The A/D coverting speed is also discussed. |
