Abstract

The authors deal with measurement of iron losses under a rotating magnetic field for electrical steel alloys used in the building of rotating electrical machines. The authors note the main characteristics needed by such devices. They then describe the realisation and the use of a machine built in the laboratory. Test results obtained for two kinds of magnetic sheet show the conjunct influences of the classical electromagnetic parameters (fundamental frequency, average flux density) and the machine design parameters closely linked to the sheet anisotropy (wavelength, radial width of the yoke). Finally, the consequences for machine design are highlighted
