FAULT-TOLERANT ELECTRIC MACHINE WITH STATOR MADE OF TWO-PHASE MATERIAL Russian patent published in 2021 - IPC H02K1/14 H02K21/16 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and can be used in electrical machines. Technical result: increased fault tolerance due to the use of the stator design, which makes it impossible for the magnetic flux to penetrate into the zone of the adjacent groove. An electric machine contains a rotor 1 with permanent magnets 2 and a magnetic core of the stator 3 with teeth 4, on which a concentric winding is located, partially made of a two-phase magnetic material. The non-magnetic zones 5 of the stator 3 magnetic circuit are located radially, in the center of each tooth 4, go out into the back of the stator 3 magnetic circuit and cross it, ensuring that the magnetic flux cannot penetrate into the zone of the adjacent groove. The thickness of the non-magnetic zone 5 is 10% of the thickness of the tooth 4, which makes oversaturation of the tooth impossible.

EFFECT: increased fault tolerance due to the use of the stator design, which makes it impossible for the magnetic flux to penetrate into the zone of the adjacent groove.
