电机驱动图像工程设备的电磁兼容性分析与设计

Electromagnetic Compatibility Analysis and Design in Motor-driven Image Acquisition System

介绍了一种由电机传动的图像设备的系统结构之后,文章首先对该系统电磁环境要素:干扰源、干扰耦合途径和敏感设备进行了详尽分析。然后针对该设备具体电磁环境特点,依据分析和计算结果,通过屏蔽、接地、隔离、滤波等干扰抑制技术进行了符合规范的电磁兼容性设计,最终使设备符合电磁兼容性规范的要求。

After a brief introduction to the system configuration of a motor-driven image acquisition system the paper gives a comprehensive analysis on the three key electromagnetic environmental elements of the equipment the source of the interference coupling path and the sensitive equipments. Then according to the definite electromagnetic traits and the consequence of analysis and computing we worked out an eligible design to restrain the EMI by means of steps like screen earthing isolation and filtering. Finally the equipment meets the requirements of EMC standards.
