FIELD: electric drives of mechanisms where motors operate into common load. SUBSTANCE: electric drive incorporating provision for transmitting slip energy directly to stator windings and for synchronizing motor speeds has two induction motors with uncontrolled parallel-interconnected rectifiers connected to their rotor windings. Connected in series with them is off-line inverter feeding rectifier and smoothing reactor. Stator windings of both motors are connected to inverter output. Control input of rectifier is connected to output voltage regulator and that of inverter, to output frequency regulator. EFFECT: reduced energy loss in drive, improved power factor. 1 dwg
