FIELD: mechanical and electrical engineering. SUBSTANCE: drive designed for displacing and tensioning strip materials and for use in thin strip processing equipment has both its there-phase induction motors connected to three-phase supply mains at different phase sequence; inserted in one of winding phases of each motor are triacs with control units and phase leads of these windings are combined and connected to capacitor whose second lead is connected to neutral bus. Such circuit arrangement provides for displacing strips at desired speed and tension. EFFECT: enlarged functional capabilities. 3 dwg
