CONTROL SYSTEM OF MULTIMOTOR ELECTRIC DRIVE OF MULTI-SECTION ASSEMBLIES Russian patent published in 2010 - IPC D21F7/02 H02P5/68 

FIELD: textile, paper.

SUBSTANCE: invention refers to control systems of electric drive of multi-section assemblies and can be implemented in multi-motor interconnected electric drives of direct and alternate current of assemblies processing band materials, for example paper-making machines, rolling mills, glass and film making lines etc, controlled with micro-processing devices. The system consists of drives of sections with controls from the micro-processing device including electric motors; output shafts of the motors are coupled to gears of working mechanisms, while power converters are installed at input; also the system includes velocity sensors and adders. A digital speed regulator is installed in the drive; the regulator includes a digital adder and a subtract counter for processing pulse signals from pulse velocity sensors arranged on transmission shafts of the first and second sections.

EFFECT: upgraded reliability of system operation, accuracy of control of velocity and of material tension.
