Abstract
The object of the invention is a rotor for a permanent-magnet synchronous machine in which a pole structure is fitted onto the surface of the rotor body structure facing the air gap. Each of the rotor's pole structures comprises at least one permanent magnet and a shell structure fitted on top of it. According to the invention, an intermediate layer made of magnetic composite is fitted between the permanent magnet and the shell structure.
