EMC测试

大家好！
我刚参加工作，从事安规方面的，有问题想请教一下大家：一般家电产品（如搅拌机）的EMC测试项目中，什么比较难通过呢？

It mostly depends on your hardware design, from my side , I think the EMI should be focused on...

传导有可能会有问题，搅拌机从EMC角度来看还是比较容易的

1.传导电压测试:主要取决于电机本身的好坏,以及接地
2.谐波电流:如有多档位控制,并且采用抽头调速,此项可能会有难度

I think you may likely have the problem in the line conduct emission of EN55014-1. This is a common problem for most of motor driven household product.

If your product has electronic circuit inside, you have better take care of the surge and ESD test of EN55014-2.

If your product gets the speed control feature, the EN61000-3-2 should pay attention.

功率骚扰不过的几率还是很高的。。
