Three unipolar flux waves are responsible for pulsating vibration in 2-pole, single-phase induction motors. The article deals with the experimental investigation of these waves. It is stated that the amplitude of the induction waves increases with the static rotor eccentricity and decreases when the speed is reduced i. e. when the load is increased. The unipolar flux waves at both ends of the rotor are different from each other and this suggests that there are mechanical and magnetic dissymmetries along the axial length of the machine.
