Asynchronous line-fed motor

An asynchronous line-fed motor comprising:

• an inductor with a magnetic circuit and a concentrated multiphase winding;
• a secondary current-carrying element arranged in immediate proximity to said inductor and separated by an air gap from said magnetic circuit;
• said magnetic circuit containing two groups of laminated cores;
• each of said laminated cores being composed of rods linked by a yoke;
• said inductor and said secondary current-carrying element being movable relative to each other to produce a traveling magnetic field;
• the lamination of said cores of the first group being perpendicular to the direction of travel of the magnetic field, said laminated cores of the first group being arranged in a row parallel with the direction of travel of the magnetic field;
• said laminated cores of the second group being trapezium-shaped, their lamination being parallel with the direction of travel of the magnetic field;
• each of said laminated cores of the first group being provided with at least one slot;
• each of said laminated cores of the second group having rods received in said slots of the adjacent laminated cores of the first group;
• said concentrated multiphase winding containing a set of coils;
• one part of said coils of said concentrated multiphase winding being wound around said rods of said laminated cores of the first group;
• the other part of said coils of said concentrated multiphase winding being wound around said yokes of said laminated cores of the second group.
