LINEAR ASYNCHRONOUS MOTOR Russian patent published in 2007 - IPC H02K41/25 

FIELD: electric engineering, electrical machines, possible use in electric motors with rectilinear or reciprocal movement of working organs and electric transportation means.

SUBSTANCE: linear asynchronous motor contains inducer with three-phased winding. In the core of secondary element, main and additional grooves are made for placement of electro-conductive mutually isolated rods, closed by common bus on one side. On the other side they are closed by moving element which contains isolating and electro-conductive parts. Electro-conductive part has a shape of comb, shelves of which are equal to main and additional grooves in terms of width and include electro-conductive and isolating parts. Moving element is provided with toothed board in connection with toothed wheel.
