FIELD: using three-phase synchronous machines for power generation.
SUBSTANCE: proposed motor-generator set has three-phase synchronous motor and three-phase synchronous generator both mounted on common shaft excited by permanent magnets. Motor and generator rotors and stators are salient-pole components. Stator poles carry stator windings. Motor and generator stator poles measure 120 electrical degrees along rotor outer circumference. Motor and stator field permanent magnets are disposed on rotor backs between its poles. Flat compensating permanent magnets installed in center of generator rotor poles are disposed in panes crossing generator axis.
EFFECT: enhanced economic efficiency of power generation.
