ABSTRACT:
A linear induction motor comprising an inductor formed of three rigidly interconnected longitudinal laminations provided with slots. The slots arranged on the side of a secondary element are adapted to receive motor windings. The secondary element includes an electrically conductive part formed of two angles and arranged on a ferromagnetic base. Horizontal flanges of the angles are arranged under the two extreme inductor laminations and apexes of the angles face each other. The middle inductor lamination is enclosed within the gap between vertical flanges of the angles so that slots therein are turned in the direction of one of the angles. The middle lamination is provided with slots arranged symmetrically with respect to the slots on the side of the first angle and suited to receive an additional winding.
