FIELD: electricity.SUBSTANCE: invention relates to electrical engineering, to electrical machines and can be mainly used in designs of synchronous electric generators with permanent magnets. The electric generator contains, at least, one stator with installed along its circumference the magnetic circuits with windings. The rotor is installed on the shaft as a disk or ring, facing one side to the stator and is equipped with magnetic elements installed along its circumference with a possibility of magnetic interaction with magnetic circuits of the stator. The magnetic circuits of the stator are designed with U-shape and facing with their radial poles towards the rotor. Each magnetic element of the rotor is designed as two permanent magnets, facing to each other with unlike poles installed radially, towards stator and connected by the magnetic circuit. The sizes of each magnet towards the rotation of the rotor and along the radius of the rotor are taken equal (15-23)? and (5-6)? respectively, where ? - the clearance between poles of magnetic circuits of the stator and magnet poles facing to them.EFFECT: technical result consists in increase of power efficiency.4 cl, 5 dwg |
