The presented paper deals with the effect of rotor geometry on the magnetic field distribution in the air gap. The magnetic field is analysed by means of the finite element method. Thid method represents, however, quite a laborious and time-consuming process. Therefore, a simpler semianalytical method for evaluation of the magnetic field distribution in the air gap and following determination of parameters for a numerical model of the machine based on lumped parameters has been proposed. This model enables considering the effect of a series of higher harmonics of the air-gap permeance on electromagnetic quantities of the machine.
