FIELD: electricity.
SUBSTANCE: invention relates to the sphere of electric engineering, to electrical machines with magnets on a stator, and can be used in electrical drives of machines and mechanisms, as well as in electrical power generators. The brushless machine comprises a rotor with a shaft and at least one gear ring on it with teeth placed around the gap circle. The stator comprises a toothed magnet core, a winding, which coils are placed to grooves of the stator magnet core. The multipole magnet system is made of hard-magnetic material and placed between the rotor and stator magnet core, fixed at the stator and magnetised so that at surfaces of the stator teeth faced towards the gap there is an equal quantity of alternating opposite poles along rotation direction of the rotor. The stator is made as a body of rotation with several teeth placed along the rotor axis of rotation. Each coil of the winding is placed to one stator groove. Over each stator tooth there are only teeth of one toothed fragment of the rotor. The number of teeth at each gear ring is equal to a half of poles placed at one stator tooth.
EFFECT: increase of the electric machine specific power and reduction of active material weight.
