ABSTRACT:
A linear induction motor comprises an inductor made of one row of main U-shaped transversely laminated cores and not more than two rows of such additional cores which are enveloped by a main polyphase distributed winding and an additional polyphase distributed winding, respectively, and a secondary element interacting with the inductor. The secondary element is provided with an electrically conductive part placed upon a magnetically conductive base. Legs of the main and additional U-shaped cores alternate and adjoin one another forming two toothless active zones through which the secondary element interacts with the inductor.
