Abstract

The invention relates to the technical field of generators, in particular to a cup-shaped outer rotor rare-earth permanent-magnet generator. The cup-shaped outer rotor rare-earth permanent-magnet generator comprises a power machine and a generator, wherein the power machine comprises a body and a power shaft; the power shaft is arranged in the centre of the body; the generator comprises a stator and a rotor; the stator comprises an annular fixing seat, a coil installation tube and a coil; the left end of the coil installation tube is fixed to the outer end of the annular fixing seat; the leftpart of the body and the annular fixing seat are fixedly arranged together; and the coil is fixedly arranged on the coil installation tube. The cup-shaped outer rotor rare-earth permanent-magnet generator is convenient to use, and has a reasonable and compact structure, and the characteristics that the generator is easy to carry, along with small volume, light weight and high efficiency because the power machine and the generator are integrated; tile-shaped magnetic steel is replaced by flat-panel magnetic steel, so that the cost of the magnetic steel is reduced; and the magnetic steel adoptsa full pole-arc, is fastened to a rotor yoke only by magnetic attractive force, avoids complex magnetic steel bonding processes, improves motor operation reliability, and is particularly suitable forfuel generators.

Description

technical field [0001] The invention relates to the technical field of generators, and relates to a cup-shaped outer rotor rare-earth permanent magnet generator, which is especially suitable for fuel generators. Background technique [0002] At present, when a fuel generator is required to supply electricity, a traditional fuel alternator is generally used. The fuel engine and the alternator are two independent machines, and the alternator is an inner rotor structure. The ring and the stator need to add a brush device, the structure is complex, and the gas engine and the alternator are connected by a coupling, which makes the power generation equipment bulky, heavy, difficult to carry, low in efficiency, and high in energy consumption. Contents of the invention [0003] The present invention provides a cup-shaped outer rotor rare earth permanent magnet generator, which overcomes the deficiencies of the prior art, and can effectively solve the problem of large volume, heavy...
