Magneto-elastic element forming method, involves metallizing ring made from magnetoelastic material on section of substrate, and performing plastic deformation of substrate, to provide desired load anisotropy to magnetoelastic material

摘要

The method involves metallizing a magneto-elastic nickel ring (14) made from a magnetoelastic material on a section of a substrate. Plastic deformation of the substrate is performed to provide a desired load anisotropy to the material. An axial load is applied on the substrate. The load applies a compressive force on the substrate. The material defines a section made from nickel. The substrate defines a crenated diameter within which the material is metallized. The anisotropy has loads that are oriented in a circumferential direction in the material, to produce a magnetic light axle (28). An independent claim is also included for a torque sensor arrangement comprising a substrate.
