ABSTRACT:
A linear induction motor comprising an inductor formed of individual transversal laminations surrounded by a main polyphase concentrated winding and provided with rods interconnected by means of a yoke. It also comprises a secondary element with respect to which the inductor moves. The secondary element has an electrically conductive part arranged on a magnetically conductive base. Each lamination is provided with two additional polyphase windings the magnetizing force of which sets up magnetic fields travelling in opposite directions transversely of inductor movement. The end faces of the lateral rods of the core structure are provided with slots arranged on the side of the secondary element and adapted to receive the additional polyphase windings.
