FIELD: electrical engineering. SUBSTANCE: three phases starting induction resistor is composed by six hollow ferromagnetic cylinders with six windings placed coaxially and corresponding ring type yokes to close magnetic circuit. Windings ends are connected in pairs order namely first plus sixth, second plus fifth, third plus fourth to make three phases connection. As a result of this construction and connections equivalent resistivity and symmetry of three phases induction resistor is provided. EFFECT: better operating characteristics of induction electric motor with three phases starting induction resistor. 1 dwg
