Linear electromagnetic drive of impact machines with retaining striker

The problems of creation and improvement of linear electromagnetic machines of impact action used in mining and construction, geological exploration, immersion of anchors, piles and other special impulse technologies are considered. The expediency of using the operating mode in the work cycle ensuring the initial supply of magnetic energy at the stage of starting the striking mass of the striker is shown. It is proved that the use of this mode makes it possible to increase the impact energy and the efficiency of an impact electromagnetic machine.
