LINEAR ASYNCHRONOUS ELECTRIC DRIVE Russian patent published in 2006 - IPC H02K41/25 H02P25/06 

FIELD: electric engineering, possible use for adjusting step movement of anchor of linear asynchronous engine.

SUBSTANCE: inducer consists of cores with coils. Electro-conductive anchor is supported by ball supports. Commutating device connects coils to voltage source through switch and is made with possible connection to voltage source of at least five coils of windings of all cores, forming primary rows along longitudinal axis of inducer, wherein up to its middle it is straight, and after middle - reversed phase alternation order. Transverse rows of core winding coils also have, up to middle - one, and after middle - opposite phase alternation order. Electric drive is provided with n additional cores with windings, outputs of winding coils of which are connected to commutating device, providing for similar commutation of their windings.

EFFECT: maintained transverse stabilization of anchor relatively to inducer.
