Abstract

The unbalanced magnetic pull is analytically modelled, referring to cylindrical rotor a.c. machines. Even if under some simplifying hypotheses (no homopolar flux, sinusoidal space distribution of the current density, no saturation, no parallel paths), various compact and significant expressions of field and force are obtained, for any number of pole pairs. Some FEM simulations and comparison with test data confirm the soundness of the proposed approach.
