Abstract: Modern synchronous electric drives require magnetic anisotropy in their rotor, manufactured from non-oriented electrical steel. Conventionally, flux barriers are placed on electrical steel sheets by removing the material, creating small recesses. While the approach is magnetically effective, the rotor is mechanically weakened. Embossed flux barriers offer an approach to stiffen the rotor mechanically, increasing efficiency. The required micro-embossing was successfully produced on an industry-grade press for the first time. Magnetic characterisation of the samples using neutron grating interferometry and a single sheet tester shows that the novel technology is transferrable from the laboratory frame to large-scale industrial manufacturing processes.
