Abstract: A generator for generating seismic pulses comprises an armature and a sta coaxially arranged relative one another. The magnet cores of both the stator and the armature have on their active surfaces alternately disposed annular projections and annular slots. The winding sections are laid into and flush with said slots. The windings of the armature and of the stator are arranged to face one another. The generator is provided with means for fixing it in a vertical and a horizontal planes. In case the armature is made two times shorter than the stator the sections of the winding of said armature are arranged in groups. The number of the sections in each group of the stator equals the number of the sections of the armature. Such arrangement of the component parts enables the armature to reciprocate and to thereby provide formation of lateral seismic waves.
