Abstract
Magnetic energy loss in electrical steel sheets account for approximately 10% of all electrical power generated, despite continuous improvements to their magnetic properties. Therefore, understanding these losses is imperative for optimizing the design of energy conversion systems. This study proposes the development of a new design of magnetic field sensor based on a shear surface acoustic waveguide on Quartz ST-cut, functionalized with a multilayer TbCo2/FeCo magnetic thin film presenting uniaxial anisotropy induced during deposition. This design enables both in-situ and ex-situ measurement of magnetic losses on the surface of ferromagnetic steel sheets. The overarching objective is to monitor magnetic behavior in electrical machines, aligning with the demands of Industry 4.0 and predictive maintenance strategies.
