LINEAR ASYNCHRONOUS MOTOR Russian patent published in 2017 - IPC H02K41/25 H02K1/34 

FIELD: electricity.

SUBSTANCE: linear asynchronous motor contains an inductor, consisting of the core and polyphase winding, the coils of which form rows in longitudinal and transversal directions. The secondary element comprises an electrically conductive part disposed on a ferromagnetic base. The electrically conductive part comprises a central portion consisting of electrically conductive rods perpendicular to the central portion. To the middle part, on both sides adjoin the side portions, each of which is formed by alternating electrically conductive rods perpendicular to the central portion, between which there are electrically conductive rods parallel to the central portion one after the other. The perpendicular rods of the side portions are interconnected to form electrically conductive rods in the central portion of the secondary element.

EFFECT: increase in traction.
