FIELD: linear electric drives.
SUBSTANCE: invention relates to linear electric drives. The linear electric drive contains a housing, in the body of which a toroidal channel filled with liquid is made, a screw-nut transmission, in which a nut fixed from rotation, connected to a hollow sliding rod, mates with a lead screw fixed in the center of an axial turbine with straight blades installed in a toroidal channel. The toroidal channel has branches equipped with check valves, in which axial pumps with check valves are installed, connected to electric motors located in the housing. In front of the turbine, in the direction of fluid movement, there is a guide vane with straight rotary blades installed with the ability to change the angle of rotation relative to the vector of the working fluid flow velocity.
EFFECT: nvention increases the speed of the linear electric drive and increases its reliability.
