地机器人的EMC问题点

1.有刷电机电拉弧产生的辐射超标。

●电机驱动产生的辐射超标。

●Flash时钟、摄像头CLOCK辐射超标。

光流传感器

●充电模块辐射超标

●雷达电源滤波


EMC问题分析及整改

●有刷电机电拉弧产生的辐射超标。

图 3

有刷电机的EMI来自哪里呢?

电机在转动换向过程中,碳刷在不断的拉电弧,电弧产生高频噪声,高频噪声通过电机引线及外壳缝隙往外辐射。

传统处理方案:

传统的处理方案有哪些不足?

●不断调整参数,费时费力;

●插件体积大,人工成本高;

●电流越大成本越高;

●整机滤波效果不理想。

我们的解决方案:

我们使用了一款拥有自主产权的滤波器—BDL,效果显著。我们来看看在3系电机上的测试数据对比图:

BDL滤波器应用实物图:

2.电机驱动产生的辐射超标

噪声产生原理:

电机驱动ICDRV8870)通过H-bridge来实现电机驱动,PWM调制信号给到H-bridge来实现转速控制,因此连接电机两引线了丰富的高频噪声,同时因为结构的原因,电机电源线最长可达到两米,给辐射噪声搭载了很好的耦合路径。

图 8

整改方案如下:

图 9

辐射噪声主要分为共模噪声和差模噪声两种形式,其中以共模噪声为主,我们在电机驱动IC DRV8870的输出脚增加共模滤波器滤除共模噪声。

3、Flash时钟、摄像头CLOCK辐射超标

图 11

解决方案——增加展频IC

图 12

效果对比图:

图 13

4、光流传感器的辐射

图 14

光流传感器的小板与主板之间的连线大约有30CM,虽然其传输的速率只有几十KHz,但由于连线长反而更容易导致辐射的问题,根据连线的长短可在主板端搭配串联不同的电阻。


5、充电模块的辐射

图 15

扫地机器人回充时,充电模块会有200MHz左右的共模噪声,可在充电模块的正负两端加共模滤波器,考虑到主板的空间,可加在充电座端。


6、雷达的辐射

图 16

雷达主要的辐射在于供电部分的噪声,雷达头的转动依靠电机来带动,电机的噪声亦会叠加到雷达的供电部分。


不同类型的扫地机器人可能有不同的EMC问题,但大致上都是一样的,如果您有什么疑问或者是新的整改经验,欢迎随时与小编交流哦。
