ELECTRIC LINEAR ALTERNATING MOTION MOTOR Russian patent published in 2007 - IPC H02K33/12 

FIELD: electric machine engineering, in particular, electric linear alternating motion motors.

SUBSTANCE: in accordance to the invention, device contains ferromagnetic tubular rotor, made in form of thin-walled pipe of magneto-soft ferromagnetic. Inside the rotor in the center guiding axis is placed, made of non-magnetic material and consisting of three sections, middle section having larger diameter compared to edge sections. On the middle section of guiding axis supporting bushing, made of nonmagnetic material, is externally and coaxially mounted in slide assembly, to which bushing aforementioned ferromagnetic tubular rotor is rigidly fastened. On edge sections of guiding axis, frames are mounted, made of pressed extruded magneto-dielectric, with conductors placed inside, forming excitation coils of direct and reverse motion. One of aforementioned frames is made with internal thread. On one of the edge sections of guiding axis, coaxially in sliding assembly, a bushing with thread, prevented from axial movements, is mounted, upon which aforementioned frame is placed in threaded connection, prevented from rotating relatively to electric motor axis.

EFFECT: expanded functional capabilities, increased reliability.
