FIELD: electric motors. SUBSTANCE: device has known electromagnetic members of electric motor which is supplied by either direct or alternating current and may be controlled in frequency of its rotation. In addition device has long shaft which provides reciprocal kinematic pair for housing of electric motor by means of longitudinal slots or recesses along length of shaft which runs through respective holes in faces of electric motor housing. Said holes follow shape and sizes of cross section of shaft. In addition shaft has threaded screw along its operating length. Said screw is connected to respective inner threaded joint which is located in coaxial with respect to shaft of rotor sleeve. Said sleeve is rigidly connected to members of rotor and is supported by ring (preferably cone) bearings which are located in face walls of housing of linear electric motor. EFFECT: increased force of pushing rod, possibility to keep shaft and pushing rod under load in arbitrary intermediate position without additional power. 1 dwg |
