FIELD: electricity.
SUBSTANCE: invention is attributed to the field of electric engineering and can be used in rotating electrical machines. The rotating electrical machine is equipped with the rotor shaft (10), the rotor core (20) and a group (30) of permanent magnets. The rotor core (20) includes a group (21) of barriers (211) for a flow, which are placed apart. At least one barrier (211) for a flow includes at least one bridge (212) connecting the inner edge (211a) and outer edge (211b) of the above barriers (211) for a flow. Permanent magnets (31) are placed in the rotor core (20) between barriers (211) for a flow when viewed in cross-sectional plane.
EFFECT: improved assessment accuracy for the rotor angular position by independent identification or control without sensors.
