ABSTRACT:
An asynchronous line-fed motor comprising an inductor with a concentrated multiphase winding and a magnetic circuit, and a secondary current-carrying element arranged close to the inductor and separated by an air gap from the magnetic circuit which comprises two groups of laminated cores formed by rods which are linked by a yoke. The lamination of cores of the first group is perpendicular to the direction of travel of the magnetic field; the lamination of the cores of the second group is parallel with the direction of travel of the magnetic field. The laminated cores of the second group are trapezium-shaped; their rods are received in slots of the laminated cores of the first group to produce active zones with flat surfaces, facing the secondary current-carrying element. One part of coils of the concentrated multiphase winding is wound around the rods of the laminated cores of the first group; the second part of the coils of the concentrated multiphase winding is wound around the yokes of the laminated cores of the second group.
