The generator is characterized in that the stator comprises a stator body, the inner side of the stator body is provided with at least one pair of stator salient poles arranged symmetrically, each stator salient pole comprises a salient pole shoe and a salient pole body through which the salient pole shoe is connected with the stator body, a gap is left between the salient pole shoes, pole shoe grooves are arranged in the salient pole shoe, an armature winding is arranged in the pole shoe grooves, an excitation winding is arranged on the stator, two corresponding salient poles of the stator form an N pole and an S pole, and the rotor comprises at least one pair of rotor salient poles. The invention also provides a power generation technology in which the brushless DC generator is used.
Description
technical field [0001] The invention relates to the technical field of power generation, in particular to a brushless DC generator and power generation technology. Background technique [0002] At present, DC generators are mainly divided into brushed DC generators and rectifier DC generators. For brushed DC generators, the stator forms a magnetic field through electric excitation or permanent magnets, the armature windings are on the rotor, and the rotor armature cuts the magnetic field to generate alternating current. Through the commutator and brushes, the alternating current generated by the rotor is converted into direct current. The armature winding is on the rotor, and a steering gear and brushes are required in addition, which has complex structure, low reliability and higher cost. [0003] For the rectifier type DC generator, the actual AC generator obtains DC power through the rectification system. Its reliability and cost depend on the alternator and rectificati...
