POWER ELECTROMAGNET OF PULSE NON-EXPLOSIVE SEISMIC SOURCE Russian patent published in 2001 - IPC

FIELD: seismic operations. SUBSTANCE: magnetic circuit of armature is separated by gap from magnetic circuit of inductor which carries three teeth in surface facing gap. Sections of teeth expand from tooth points to roots to provide for rise of induction of magnetic field in working parts of gap above tooth points. Two-section structural circuit of magnetic circuit of electromagnet with double-coil excitation winding is employed to rise power developed by electromagnet. EFFECT: raised seismic efficiency and technical parameters of seismic source. 1 cl, 2 dwg
