摘要
介绍了由符合嵌入式微机标准PC/104的主机板及电流传感器等组成的鼠笼电机断条在线检测仪系统的结构和原理,给出了的部分框图,提出了利用A/D卡来采集鼠笼电机运行特性参数,并对其进行快速傅立叶分析,从结果中判断电机有无断条的方法,这给企业用户了解电机的状态带来了方便。
An auto-detection instrument of broken-bars working online for squirrel-cage induction motors is put forward, which is based on PC/104 microcomputer. The structure and theory of the system are given. It uses the analog-digital chip to get the data of squirrel-cage motors. Thence the instrument will analyze the data with Fourier transformation to judge whether the motor has any broken-bars.
