MULTI-MOTOR ELECTROMECHANICAL DRIVE AND OPERATION METHOD THEREOF Russian patent published in 2016 - IPC H02K7/116 H02P5/46 H02P6/16 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, namely to designs of multi-engine electromechanical drives with microprocessor control. Said multi-engine electromechanical drive (MEMD) has body and at least three servo drives, each of which can include one-, two-or three-stage harmonic reducing gear and has output shaft with cam; said gearing with cylindrical gear wheel teeth of which are formed by cycloidal surface interacting with single-toothed gears are cylindrical cams fitted on output shafts of actuating electric drives. In bearings in body there is main shaft with its angular position sensor. All sensors of angular position of output shafts of electric drives and main shaft are connected by interface bus with main control unit. Motors are brushless direct current electric motors with excitation from permanent magnets. Each stage of harmonic drive can have gear ratio to 30, with total gear ratio of three-stage reduction gear up to 27,000.

EFFECT: technical result is increase of reliability of electromechanical drive.
