FIELD: electrical engineering. SUBSTANCE: technical and economical indications of starting choke are improved thanks to insertion of single-phase capacitor-start motor into circuit. In this case, choke has inductance Lst=(1-1/Kst):ω2cw, where cw is capacitance of working capacitor, ω is angular frequency of network voltage; Kst is factor of increase of torque at start of motor. EFFECT: improved technical and economical indications. 1 dwg
