Abstract

The invention provides a rotor structure and a generator, and relates to the technical field of generators. The rotor structure comprises a rotating shaft, a rotor core, an air guide structure and a plurality of magnets. The rotor core is installed on the rotating shaft, a first through hole is formed in the rotor core, and the first through hole penetrates through the two end faces of the rotor core in the axial direction of the rotor core. The plurality of magnets are arranged in the outer circumference of the rotor core at intervals, and a gap is formed between every two adjacent magnets. The air guide structure comprises a first end plate and a fan blade structure. The first end plate is connected to one axial side of the fan blade structure, and the first end plate is arranged betweenthe fan blade structure and the rotor core and covers the gap. The first end plate is provided with a second through hole used for air suction of the fan blade structure, and the second through holeis communicated with the first through hole. The invention further provides a generator which adopts the rotor structure. The rotor structure and the generator provided by the invention can solve thetechnical problems of difficult installation, difficult processing and poor heat dissipation performance in the prior art.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to a rotor structure and a generator. Background technique [0002] Generally speaking, the rotor structure of a permanent magnet generator is generally embedded with magnetic steel radially evenly distributed on the rotor yoke, and the rotor yoke is formed by lamination of punched sheets. On the one hand, after the rotor yoke is embedded with magnetic steel, the teeth of the rotor yoke On the other hand, the magnetic steel has strong magnetism, and it is not easy to align when it is embedded in the rotor yoke. The generator mainly relies on the air gap for heat dissipation, and the heat dissipation performance is not good. Contents of the invention [0003] The purpose of the present invention includes providing a rotor structure, which can solve the technical problems of difficult installation, difficult processing and poor heat dissipation performance in the prior art.
