Perspectives of preliminary magnetic energy accumulation in a linear electromagnetic drive inductances system have been considered. This magnetic energy accumulation mode provides the increase of final speed, striker impact energy and electric drive efficiency. The electromagnetic drive circuit variant where magnetic energy is accumulated when the striker is restrained at initial acceleration interval has been analyzed. The basic demands for the magnetic energy accumulation mode have been formulated. The effective methods of magnetic energy accumulation have been developed. The methods allow to increase twice and more the impact energy and efficiency of impulse electromagnetic drives.
