Cutting and Stacking Effects on Fatigue performance of Electrical Steels (CUTSUR-FES)
Purpose and goal
The project aims to understand how cutting and stacking of electrical steel sheets affect fatigue and magnetic performance. We compare mechanical and laser-based cutting, develop repeatable fatigue testing for single sheets and stacks, and link edge quality and microstructure to durability and functional performance to support more efficient, reliable, and scalable motor production.
Expected effects and result
We expect validated fatigue-test methods for stacks, comparative data for cutting techniques, and magnetic measurements before and after cycling loading. We also map links between microstructure, cutting methods, fatigue life, and magnetic degradation. Expected effects are improved motor durability, reduced material use, better design decisions, and guidance for industrial adoption of optimized cutting processes.
Planned approach and implementation
The project characterizes baseline material to define reference properties, evaluates cutting methods, and develops repeatable fatigue-testing methods in single sheet and stacks. Selected cutting routes are tested mechanically and magnetically before/after fatigue to track performance changes. We compare cut-then-stack vs stack-then-cut, study microstructure and failures, and screen promising routes under thermal cycling to assess industrial feasibility.
