Novel axial magnetic flux double-salient permanent magnet generator

Abstract

The invention discloses a novel axial magnetic flux double-salient permanent magnet generator. The technical problem that an existing generator is excessively complex in structure, large in self energy consumption and the like is solved. According to the technical scheme, the novel axial magnetic flux double-salient permanent magnet generator comprises a rotor, a generator outer stator, a generator inner stator, a permanent magnet ring and a rotor shaft. The generator inner stator is embedded in the generator outer stator, and a gap is reserved between the generator inner stator and the generator outer stator, the permanent magnet ring is installed in the gap, the rotor shaft is arranged in the center of the rotor, and the rotor shaft and the rotor are fixed into a whole; the rotor shaft penetrates through the center of the generator inner stator and is not in contact with the generator inner stator; the rotor is located above the generator outer stator and the generator inner stator. By means of the novel axial magnetic flux double-salient permanent magnet generator, a double-salient permanent magnet motor and an axial magnetic flux motor are organically combined; the novel axial magnetic flux double-salient permanent magnet generator has the advantages of being high in efficiency, high in power density, compact in structure, low in noise and low in starting air speed.

Description

technical field [0001] The invention relates to a generator, in particular to an axial magnetic flux double salient permanent magnet generator, which belongs to the technical field of power generation. Background technique [0002] In new energy power generation, the research on generators is currently mainly focused on three types of generators: brushless doubly-fed generators, permanent magnet synchronous generators and doubly salient pole generators. [0003] The brushless doubly-fed generator can adjust the frequency of the excitation current according to the change of the prime mover's speed to achieve constant frequency output. By changing the amplitude and phase of the excitation current, the generator's active and reactive power can be independently adjusted. Since the air gap of the brushless double-fed generator is large, the excitation reactive power of the control winding excitation converter is also large, so it is not suitable for low-speed direct-drive generat...
