🔧 What Type of Shielding Protects Encoders from EMI? Electromagnetic interference (EMI) is a common challenge for Sin/Cos encoders in high-power IPM motors, especially in EVs. Protecting these encoders with proper shielding ensures accurate feedback and reliable motor performance. 🚨 Essential Shielding Techniques: Shielded Cables: Encoders with braided or foil-shielded cables block EMI from nearby high-power components. Metallic Enclosures: Housings made of conductive materials, such as aluminum, create a Faraday cage effect to shield encoders from external interference. Ferrite Beads: Installing ferrite cores on cables suppresses high-frequency noise, protecting signal integrity. Grounding Practices: Effective grounding dissipates electromagnetic energy and prevents signal contamination. PCB Layout Optimization: Proper spacing and routing in encoder electronics minimize internal interference. 🌟 Why It Matters: Without adequate shielding, EMI can distort encoder signals, leading to inaccurate position feedback, inefficient motor control, and potential system failure. Shielding ensures consistent performance in high-power environments. 💡 Pro Tip: Combine multiple shielding methods for robust EMI protection, especially in noisy environments like EV powertrains. Regularly inspect cables and grounding connections to maintain effectiveness. 🌐 Learn More: Dive deeper into shielding techniques and best practices for protecting encoders in our latest guide: https://lnkd.in/gysW99vG 💬 What’s your preferred method for shielding encoders from EMI?

Looks like an innocent mistake, but this can cause a great deal of EMI troubles. To put it simply, think about your chassis as acting like a Faraday cage for your product. This should allow you to contain high levels of emissions from your product and provide a high level of protection from external emissions into your product. The problem happens when we use pigtail connections. First of all, we break this Faraday cage, so now the emissions can escape, and external emissions can access our device. The second important part is that we are basically setting free common mode currents, which are much more effective in radiating emissions compared to differential mode currents. This means that even a tiny amount of common mode current is going to create the same level of radiation as a larger differential mode current. So when we use shielded cables, we have to remember that this will only be effective if we make a 360-degree low impedance connection between the shield of the cable and the chassis of the product. In this way, the shield of the cable will act simply as an extension of the Faraday cage. I hope this helps, Dario fresuelectronics.com P.S.

For the special needs of the mid-to-high-end technology industry for PCBs, we have been using high-TG boards from brands such as KB, SY S1000-2, ITEQ 160 180, Panasonic, Ventec, etc. to ensure the quality and performance of the products. The TG values of boards are divided into three types: namely ordinary Tg130, medium Tg150, high Tg170 and tg180. And the advantages of high TG boards are stable and obvious: 1. Higher applicable frequency band: excellent performance in the field of 5G communication and high-speed data transmission, and can play a more stable and reliable performance. 2. Better manufacturing adaptability: in terms of manufacturing, stacking, multi-layer board design, stacking graphic design, etc., it has better processing process maintainability, reliability and compatibility with other materials. 3. More in line with environmental protection standards: Not only have high performance, but also meet the requirements of environmental protection. #pcbfactory #pcb #pcba #manufacturer #automation #mutilayerpcb #production #CircuitBoardProduction #technologyinnovation #manufacturingtechnology #engineeringinsights #electronicdevices #industryupdates #pcbfabrication

Designing an effective input filter for a switching power supply is critical for ensuring noise reduction, meeting EMC standards, and ensuring the system operates efficiently. By carefully selecting components, optimizing the layout, and verifying performance through testing and simulation, you can achieve a well-performing filter that minimizes EMI and provides a clean input to the power supply. 1. Common Design Challenges : 1. Trade-Off Between Size and Performance : Larger inductors and capacitors may provide better filtering but increase size and cost. 2. Component Selection : Low ESR capacitors and high-current inductors are required for optimal performance, but finding the right balance between cost and performance is a challenge. 3. Thermal Management : Ensure that the filter components are adequately rated for temperature and power dissipation. #Filterdesign #Filter #LCL #EMC #CM #DM #LLC #PowerElectronics #HardwareDesign #ComponentSelections #ESR
