The paper is aimed at the analysis of the influence of the third spatial harmonic of the MMF on the stator currents and the torque of a five-phase synchronous machine with surface-mounted permanent magnets. The analysis is carried out on the basis of the method of space vectors and symmetricalcomponents of instantaneous values of currents and voltages. The mathematical description of the machine is derived and the results of simulations are presented. they show how the third spatial harmonic of the MMF produced by the permanent magnets give rise to the third spatial harmonic of the current layer and magnetic flux in the yoke. The third spatial harmonic of the current layer results in distortion of currents and torque.
