ELECTRIC DRIVE Russian patent published in 2003 - IPC

FIELD: permanent-magnet machines for miscellaneous drives of fans, compressors, electric vehicle wheels, and the like. SUBSTANCE: electric drive has rotor made in the from of two disks whose teeth on their inner circumference form rotor poles with axially magnetized cylindrical magnet disposed between disks; and stator made in the form of coils distributed over circumference for face interaction with rotor poles which are mainly mounted in pole-to-pole gaps of rotor. The latter may be sectionalized and disks may be made in the form of plates so that poles of one disk are disposed between those of other disk in same plane and magnets of adjacent sections are facing one another by like poles. Disks may be built integral with magnet to form its poles. Rotor poles are disposed in planes perpendicular to machine axis and stator poles are mounted for face interaction with rotor poles thereby making it possible to reduce radial dimensions of machine. Plate-shaped disks enable optimization of machine size depending on magnet used, stator design, desired power output, and size of structure to receive electric drive. EFFECT: facilitated manufacture and enhanced strength of rotor; optimized size of drive. 16 cl, 29 dwg
