ELECTRIC DRIVE (OPTIONS)

The invention refers to magnetoelectric machines. It can be used when manufacturing different-purpose electric drives-for instance, in fans, compressors, electromobile's wheels, and so forth. It comprises a rotor made in the form of two disks, the teeth of which on the outer or inner circumference make up rotor poles and an axially magnetized cylindrical magnet (placed between said disks). The stator (made in the form of coils that are distributed over the circumference and that are installed predominantly in the space between the rotor poles) provides for the possibility of the end face interaction with the rotor poles. The rotor could be made as a multi-sectional unit. In this case said disks have the plate-like shape, owing to which fact the poles of one disk are located between the poles of another disk in one plane, while the magnets of adjacent section are oriented towards one another with like poles. The disks could be made integral with a magnet in such a manner that they serve as magnet's poles. The design is characterized by a high degree of adaptability to streamlined manufacture of the rotor and by rotor durability. Owing to the fact that rotor poles are located in the planes perpendicular to device axis and stator poles are located in such a way that a possibility of the end face interaction with rotor poles is provided for, it becomes possible to reduce the radial size of the device. A plate-like shape of said disks makes it possible to optimize the size of the device depending on the magnet and stator used, required power and the size of a device, in which this electric drive is supposed to be mounted.
