Abstract
The utility model discloses a constant voltage permanent-magnet generator which rotor is provided with rare earth permanent-magnet steels and an electrically energizing device which can automatically compensate armature reaction when the generator is on load to reach the goal of automatic constant voltage.
Description
Technical field
The utility model relates to gen-set, especially a kind of automatic constant-pressure permanent magnet generator.
Background technology
The minitype permanent magnetism electric generator structure is simple, and volume is little, but can not automatic Regulation, and voltage waveform is poor, brings many problems to use, and it is difficult to promote.
Summary of the invention
The purpose of this utility model is the shortcoming at above-mentioned existence, designs the design of electric excitation automatic pressure regulating device and special armature winding, and not only waveform is good, and can be singly, three-phase is general, and pressure regulation compound excitation energy can also be provided.
The technical solution of the utility model is: a kind of constant voltage permanent magnet generator, design has special winding on the stator of this constant voltage permanent magnet generator, this winding is a kind of simple single layer winding, this kind three phase windings can be singly, three-phase is suitable for, also can provide the harmonic excitation energy, and rare-earth permanent magnet steel is housed on the rotor, electric excitation winding and rectifier diode also are housed, the self-excitation compensation is in order to constant voltage.
Advantage of the present utility model is: 1) realized the automatic Regulation of permanent magnet generator, made voltage regulation performance obtain large increase; 2) good voltage waveform can also be singly, three-phase is suitable for; 3) simple in structure, reliable, except the minority diode, need not other electron component; 4) the technology tradition is easy to promote, and forms industrialization.
