Precision Control in Laser Cutting of Motor Cores: Achieving 0.01mm Tolerance

Laser cutting technology revolutionizes motor core manufacturing with ±0.01mm precision, replacing the traditional stamping process to achieve mold-free, efficient and low-cost pilot production. The core breakthroughs include: dual-drive gantry system to ensure static accuracy, fiber laser to stabilize the spot and reduce burrs, intelligent pulse process to control thermal damage and achieve high roundness of the microvia, magnetic polishing and visual inspection technology to control the stacking error. The technology has been applied to new energy automobile flat wire motors (slot precision ±0.015mm), medical micro motors (0.05mm line width) and other fields, improving energy efficiency by 2% and reducing R&D costs by 80%. In the future, it will be developed in the direction of AI parameter optimization, picosecond cold processing and cutting inspection integration.

Motor Core Design: The Superiority of Silicon Steel And Selection Secrets (+2025 Guide)

This comprehensive guide examines silicon steel's pivotal role in motor core design, particularly for electric vehicles (EVs), driven by its optimal balance of electromagnetic performance and cost efficiency. Silicon steel (0.5%-6.5% Si) reduces iron losses to <4.5W/kg and achieves 1.7-2.0T magnetic flux density, enabling >95% motor efficiency. Key classifications include cold-rolled non-oriented silicon steel (CRNGO) for isotropic performance in high-speed EV motors (15,000-20,000rpm) and grain-oriented silicon steel (CRGO) for transformers. Thinner laminations (0.15-0.27mm) cut eddy current losses by 45% versus traditional 0.35mm sheets but require precision laser cutting (heat-affected zone <0.1mm), increasing production costs by 15%.
