FIELD: electric engineering. SUBSTANCE: method involves alternation of number of pairs of rotor poles, separation of coils in each stator phase windings in groups, delay of electric oscillations which are produced by each separate coil by means of delay line, and addition of such oscillations at terminals of corresponding coil groups; terminals of coil groups are connected to terminals of corresponding phases of generator. This results in possibility to generate one oscillation with summed amplitude at terminals of each coil group and to generate at generator terminals low- frequency current with high amplitude. EFFECT: possibility to generate both high-frequency current for welding as well as supply line current which frequency is 50 Hz. |
