FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, in particular to linear valve electric motors, namely, a method for ensuring the translational movement of the movable part of the electric motor, namely the rotor in the form of a slider. The stator bore, located in the magnetic field of permanent slider magnets with a constant radial magnetic resistance, is formed with a constant magnetic resistance closed through the slider elements along the spiral of the toothed screw. Thus, the concentration of the magnetic field of the stator on the toothed screw and the movement of the vector of the magnetic field of the stator in the non-magnetic gap between the stator and the slider along the trajectory set by the specified toothed screw are ensured. By means of which the vector of the magnetic field of the stator within each turn of the toothed screw interacts with the vector of the magnetic field of the slider. A force vector F with a driving axial component Fx is formed. The rotational-translational motion of the magnetic field of the stator is transformed into the translational motion of the slider.
EFFECT: increasing the specific power of the electric motor, reducing the pitch of the pole division, increasing the positioning accuracy of the moving part of the electric motor.
