FIELD: electricity. ^ SUBSTANCE: axial two-input contactless dynamo includes body, permanent multipolar magnet of induction coil subexciter, lateral axial magnetic conductor with polyphase armature winding of subexciter, single-phase winding of subexcitor and auxiliary excitation winding of exciter which is connected to DC power supply source through contacts, inner axial magnetic conductor with polyphase armature winding of exciter and single-phase excitation winding of main generator, lateral axial magnetic conductor with polyphase armature winding of main generator, shaft fixed in bearing assemblies and rigidly bound with permanent multipolar magnet of induction coil subexciter and inner axial magnetic conductor by means of respective discs. Single-phase excitation winding of exciter is connected to polyphase armature winding of subexciter through polyphase double-wave rectifier. Single-phase excitation winding of main generator is connected to polyphase armature winding of exciter through polyphase double-wave rectifier. ^ EFFECT: possibility of adding and conversion of mechanical power and DC electrical power into AC polyphase electrical power, simplification of magnet system manufacturing technology, quality improvement of generated voltage. ^ 1 dwg |
