FIELD: electromechanical engineering; wind- electric power plants. SUBSTANCE: synchronous generator has rotor and stator whose magnetic circuit is built up of magnetically isolated cores carrying ac winding coils. Novelty is that rotor has even number of magnetically isolated cores with electrically isolated field coils; even and odd field coils are connected to DC supply of different polarity; rotor is designed for partial connection of field coils so that only those located within the region of stator ac winding coils connected to load are energized. Generator provides for producing current at industrial frequency of 50 Hz at low rotor speed without reduction unit for transmitting mechanical energy from slow-speed drive motor, such as wind-electric plant, with low power requirement for excitation. EFFECT: enlarged functional capabilities. 2 dwg |
