EMC Testing for Power Tools

Betele Power Tools Engineering Team explains why adding more magnetic rings is not always the best solution for EMC testing failures in cordless power tools. The article covers the root causes of EMC problems in rotary hammers and demolition hammers—including high-frequency switching, DC-DC converters, and motor noise—and provides a practical troubleshooting framework based on three key elements: noise source, coupling path, and sensitive circuit. It emphasizes that PCB layout, grounding design, and BMS protection are more effective than simply adding ferrite components. Published August 18, 2026 as part of Betele Technical Insights.
