ABSTRACT:
An asynchronous line-fed motor comprising an inductor composed of individual laminated cores which form two rows extending in the direction of travel of the magnetic field. Each laminated core is formed by rods having pole shoes at one end and enveloped by yokes at the opposite end. The pole shoes of the laminated cores of the second row link the laminated cores of the first row to one another and are interposed between the pole shoes of the laminated cores of the first row. The yokes of the laminated cores of the first and second rows face in opposite directions. Coils of a concentrated multiphase winding are wound around the yokes of the laminated cores. The motor also includes a secondary current-carrying element disposed in the air gap between the pole shoes of the laminated cores.
