electric drives for press equipment, computer data input/output devices, and the like. SUBSTANCE: two induction motors are connected to single-phase supply mains through three capacitors and two switching members in the form of triacs with control units. Proposed connection of capacitors and triacs to motor windings and to supply mains ensures reversible control of tape speed and tension. EFFECT: enlarged functional capabilities. 1 dwg
