Abstract
The invention refers to magnetoelectric machines and comprises a rotor made in the form of at least two disks, the magnetized disks have circumferential arrayed like poles and an axially magnetized polygon or cylindrical magnet placed between the disks. The stator comprises a winding selected from the group consisting of a coil winding and a wave winding coils that are distributed over the circumference and are installed predominantly in the space between the rotor poles provides for the possibility of the end face interaction with the rotor poles. Each of at least two disks could be made of a non-ferrous material with embedded magnets, and rotor further comprises ferrous metal plates, each of the plates is attached on an outer surface of each disk and comprises a ferrous metal cylinder for interconnecting a magnetic flux between ferrous metal plates. The rotor could be made as a multi-sectional unit. The disks could be made integral with a magnet in such a manner that they serve as magnet's poles. It becomes possible to reduce the radial size of the device. A plate-like shape of the disks makes it possible to optimize the size of the device depending on the magnet and stator used,…
