An analytical model is presented for defining the forces applied by every radial and axial bearing of the actuator, which allows identifying cross-couplings and deviations from the ideal forces, an essential step for their minimisation. A validation campaign is performed to guarantee and assess the accuracy of such a model employing a magnetic bearing demonstrator that features a dual hetero/hompolar machine design.text::conference output::conference proceedings::conference paper
