A device for driving in building elements includes an inductor system with active layer arranged as a set of coils with magnetic conductor, those are installed in the body and connected to the alternating current power supply source, movable element, it includes magnetic-soft poles mounted on the rod, between those permanent magnets are placed, the long and radial axes of the coils and the poles coincide, elastic elements between the inductor system and the movable element, head installed between the body and the drawn-in element. Between the coils and the power supply source in series with the coils an energy control block is installed, this has two half-period rectifiers that are opposite connected, each of those is equipped with a device for control of current amplitude, at that the maximum of half-wave of current coincides with direction of motion of the movable element with maximum energy. |
