High-speed in-situ characterisation of Aeroperm Ribbon

Aeroperm feedstock is produced using planar flow casting, then undergoes continuous ultra-rapid annealing to produce its novel electromagnetic properties.

This project aims to enhance production quality by developing a high-speed in-situ characterisation system that enables real-time parameter detection and feedback to the production system, allowing for the correction of defects during production on casting and web handling systems.

Project background

Kite Magnetics’ advanced ultra-efficient soft magnetic material, Aeroperm©, is designed to perform more work and reject up to 97% less heat than the incumbent monopoly material, electric steel, in the stator cores of generators and motors, such as those used in high-speed applications, including electric vehicles. Aeroperm feedstock is produced using planar flow casting and then undergoes continuous ultra-rapid annealing to produce its novel and valuable electromagnetic properties.

This material can significantly improve motor efficiency and reduce the overall weight of the motors and associated systems, leading to enhanced energy efficiency and performance in electric passenger, commercial, and heavy transport vehicles and aerospace applications, to name only a few.

Real-time monitoring of the manufactured magnetic ribbons is essential to detect and correct defects during production, ensuring the high-quality product necessary to achieve these performance benefits.

Project objectives

Develop and deliver a high-speed in-situ monitoring system that characterises the magnetic ribbons’ physical properties during production.

The system will include commercial off-the-shelf sensors and processors to perform the following measurement and monitoring tasks:

• Ribbon width and edge roughness measurement
• Three-point ribbon thickness or surface mapping
• Surface quality assessment, including defect detection (pits, voids, scratches)
• Imagery capture of ribbon surfaces
