AC DRIVE Russian patent published in 1997 - IPC

Abstract RU 2085017 C1

FIELD: driving hauling trains, metal-cutting machines and mechanisms in comprehensive speed variation range. SUBSTANCE: ac drive slip-ring induction motor has its rotor windings closed to triac star, one stator winding connected to DC power supply and two other ones interconnected in series and connected through controlled rectifier to ac three-phase or single-phase supply mains. Triac control angle and that of controlled rectifier diodes should be chosen proceeding from intermittent current in stator winding. EFFECT: improved design. 3 dwg
