LINEAR INDUCTION MOTOR Russian patent published in 2017 - IPC H02K41/25 

FIELD: electricity.

SUBSTANCE: linear induction motor (LIM) contains an inductor (1), consisting of a core (2) and three-phase winding (3), and a secondary element(4), containing a core (5) with the grooves, containing the central straight sections and adjacent to them from both sides at equal angles two lateral sections. The electrically conductive rods repeat the shape of the grooves and are closed from the both sides by electrically conductive elements (6). The electrically conductive rods, lying in the side parts of the grooves, consist of two parts, connected to each other by the reed relay closing contacts, the windings terminals (7) and (8) of which are connected to the direct current source through the reed relays. The inductor (1) contains the permanent magnets (10), placed on both its sides and mechanically connected to it.

EFFECT: increase of the lateral stabilization force, occuring at the linear induction motor inductor displacement relative to the secondary element.
