LINEAR ASYNCHRONOUS MOTOR Russian patent published in 2010 - IPC H02K41/25 

FIELD: electricity.

SUBSTANCE: linear asynchronous motor contains an inductor composed of a core (1) with a multi-phase winding (2), a secondary element (3) containing a core (4) in the grooves whereof, one over another, insulated conductive rods are positioned (5) closed on one side with a common conductive bus (6) and on the other - with a closing cylinder (7) composed of a conductive part and an insulating part, with a handle (8). The grooves of the core (4) of the secondary element (3) contain a central part (9) perpendicular to the horizontal axis of the closing cylinder (7). Adjacent thereto at identical angles on both sides are side parts (10 and 11). All the conductive rods shaped matches that of the groove. Adjacent to the central parts (9) on both sides are additional parts (12 and 13), serving as their extensions and perpendicular to the closing element (7) axis.

EFFECT: increased draught power.
