SINGLE-PHASE ELECTRICAL MACHINE Russian patent published in 2014 - IPC H02K19/06 H02K21/38 

FIELD: electricity.

SUBSTANCE: invention relates to electrical machinery, and namely 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 proposed electrical machine includes a toothed rotor, a stator, which includes a toothed magnetic conductor with even number of teeth, a single-phase winding and a multiple-pole magnetic system made from hard-magnetic material, which is located between the rotor and the magnetic conductor of the stator, fixed on the stator and magnetised so that equal number of alternating opposite poles is provided on each tooth of the stator; with that, adjacent poles referring to different stator teeth are similar poles, and number of rotor teeth is lower by two times than the number of poles on all stator teeth.

EFFECT: technical result achieved by means of this invention consists in increase of specific power of an electrical machine at simultaneous decrease of weight of active materials.
