A GSTP funded activity utilised the benefits of additive manufacturing with laser powder bed fusion technologies to improve the material properties of soft magnetic material.
A rotor for a magnetic bearing was designed, acting as a demonstrator, and manufactured from a nickel iron alloy. The demonstrator was successfully verified through testing and inspection, raising the technology readiness level to 4. The rotor reached a part density of over 99.5 % and a tensile strength above 365 MPa, with improvements in the magnetic properties of the nickel iron alloy, including high permeability and low coercivity. Furthermore, the manufacturing of a light weight, lattice-like structure permits the creation of more complex design elements, with an increased design freedom, which improves the overall efficiency of satellite actuators.
