| 摘 要： | 设计出一套换向器跳动测试仪,用于测量直流电机换向器超速前后片间跳动和圆周跳动。根据电涡流传感器的测量原理,电涡流传感器将传感器探头与换向器片间的距离转换成电压值,再经过dsPIC30F6014数字信号控制器进行采集、处理、计算,并与上位机交换数据。给出了以dsPIC30F6014和电涡流传感器为核心的系统硬件设计和软件控制流程,并对实验结果进行了分析。该仪表既可以单独使用,也可以于上位机联合,实现测量系统的多功能化。

| Abstract: | Designed a commutator jumpiness measuring instrument,which was used to measure jumpiness between slices and circumferential jumpiness of commutator in DC machine.According to the theory of current eddy sensor,the current eddy change the distance between detector and commutator to voltage,then the dsPIC30F6014 sample,calculate the signals,and send it to computer.It presented the design for hardware and control flow in software with the center of dsPIC30F6014 and current eddy sensor,and analyzed the results.The instrument could be used alone,or associated with computer to achieve the functionality. |
