In the paper a non-linear mathematical model for the performance assessment and the design improvement of small single-phase PM synchronous motor is proposed. The calculation of the model parameters is carried out by 2D FEM analyses suitably corrected to take also into account of the 3D effects. The procedure implemented in a numerical code allows to investigate significant design aspects related to a motor configuration adopted for small fan appliances.
