The paper presents the algorithm of conversion of the finite element computations using the 2D model of permanent magnet machine into the set of its main exploitation parameters. The novelty of proposed method is founded on representation of the air-gap field at any load conditions by means of linear combination of few basis functions. These functions are extracted from magnetostatic solutions of FE model at chosen loads. The effect in third dimension of the slot skew is incorporated through low-pass filtering in spectral domain.
