LINEAR ASYNCHRONOUS ENGINE Russian patent published in 2006 - IPC H02K41/25 

FIELD: electric engineering, possible use for construction of electric engines with rectilinear or reciprocal movement of working organs and for high-speed ground-based transportation means.

SUBSTANCE: device has primary inducer and a secondary element made of electric-conductive material. Inducer consists of a core and a three-phased winding. Winding coils form rows in longitudinal and transverse directions. Longitudinal rows of winding coils have direct orders of phase alternation. Transverse coil rows before the middle have a certain one, and after the middle - the opposite order of phase alternation. Engine is equipped with additional inducer, positioned in parallel to primary one. Coils of its winding have the same phase alternation order. Secondary element is formed by a combination of five electric-conductive bands shaped like parallelepipeds. Side and middle stripes have lesser active resistance, than stripes, positioned between them. Both inducers are mounted on common ferromagnetic base.

EFFECT: increased transverse stabilization force.
