Abstract: A synchronous machine having a stator and a rotor, of which one, preferably the stator, is provided with a three-phase, symmetrical, Y-connected armature winding intended to have a sinusoidal line voltage or a sine-wave supply current, whereas the other, preferably the rotor, carries a field magnet system. The magnetic flux generated in the air gap between the ferromagnetic cores of the stator and the rotor and linked with the armature winding has a density whose mean value, as determined over the axial extension of the air gap, varies along the air gap in its circumferential extension in accordance with a uniform periodic function whose positive and negative half-periods are mirror images of one another and whose period coincides with the extension of two pole pitches of the field magnet system, and whose shape deviates from a purely sinusoidal shape. Within one-half of one positive half-period of the function f(.alpha., .beta.)=1 for 0.ltoreq..alpha..ltoreq..pi./2 and f(.alpha.,.beta.)=cos(.alpha.-.beta.)-sin.beta./1-sin.beta. for .beta.
