Understanding EMI Filter Role in the Robotics and Automation Industry
How Does EMI Filters help in the Robotics and Automation Industry?

EMI/EMC filters act as a crucial barrier, preventing unwanted electrical noise from disrupting the seamless function of both robots and sensitive electronic equipment.
EMI noise can occur as conductive and radiative noise. Radiated EMI noise typically isn’t much of a problem in BLDCs for robotics. The conductive EMI can flow through the common DC current path or through parasitic elements or ground planes.
Conductive EMI has two types: common mode(CM) and different mode (DM). CM noise flows in the same direction through circuit elements and returns through the ground plane. DM noise flows in one direction through one element and will return by other elements in the circuit.
Generally speaking, EMI/EMC filters act as a crucial barrier, preventing unwanted electrical noise from disrupting the seamless function of both robots and other sensitive automation equipment. As technology continues to advance, the synergy between EMI filters and robotics becomes increasingly important in maintaining productivity of critical systems.
For this reason, DOREXS has been committed to EMI filters for nearly 10 years to provide EMI Consulting to help customers solve their EMI Issues. In order to meet the needs of the market development, to develop marketing programs, to provide customers with reliable, inexpensive products and quality services.
DOREXS EMI Solutions can help you to mitigate the risk of EMI
In order to reduce manufacturing costs, manufacturers should consider EMI shielding issues at the earliest stage of product design. The best solution to this problem is to use an EMI power line filter and install a power line or EMI filter at the power entry point of the device. An EMI Filter can not only with conducted emissions, but also in meeting immunity and fast transients requirements along with radiated emissions too.
How to Select an appropriate EMI Filter?
The design parameters of EMI Filter include:
Meanwhile in order to get the most efficiency, reliability, and proper operation from the EMI Filter. To design a good filter, the pass band must be defined just as the potential interference frequencies. As any filter schematic only an approximation of the filter circuit especially at higher frequencies, in real life the filter components exhibit tolerance, and saturation.
