FIELD: electrical engineering.
SUBSTANCE: present invention relates to electrical engineering and can be used in three-phase asynchronous electric machines with rotor excitation from permanent magnets. Device of three-phase asynchronous motor includes stator with symmetric three-phase double-layer winding and rotor with short-circuited winding and two diametrically located slots in which are placed opposite radially magnetized permanent magnets from NdFeB alloy.
EFFECT: technical result consists in increasing of specific power and reducing of electromagnetic torque of the electric motor.
