DUAL-MOTOR DRIVE FOR DISPLACING CONTINUOUS MATERIALS Russian patent published in 2003 - IPC

Abstract RU 2204881 C2

FIELD: drives for tensioning continuous materials such as thin ribbon blanks. SUBSTANCE: dual-motor drive has two three- phase induction motors connected to three-phase supply mains with different phase sequence; inserted in one of phase windings of each motor are triads with control units; starting leads of these phase windings are shorted out by capacitor. Such circuit arrangement enables displacement of ribbon blanks at desired speed and tension of blank. EFFECT: enlarged functional capabilities. 1 cl, 2 dwg
