In addition, the exciter stator pole lamination and the magnetic field winding are redesigned and reconfigured, so that the radiation area of the winding is enlarged, and a radiation condition is good; and moreover, due to the adoption of a distributed magnetic field winding, the brushless the sinusoid of an air gap magnetic field waveform is high, excitation power is high, an excitation winding is easily fixed, mechanical strength is strong, and a model machine is detected to have ideal effects.
Description
Technical field
The present invention relates to electric generator structure, specifically be meant a kind of brushless generator of not adjuster with voltage.
Background technology
General traditional brushless generator all must be with automatic voltage regulator (AVR), and its action principle first is controlled the exciting power that generator main winding (or auxiliary winding) provides, and keeps constant to reach generator voltage; It two is by the voltage of generator main winding (or auxiliary winding) from air gap remanent magnetism magnetic field induction; After voltage regulator (AVR) rectification, provide exciting power to exciter stator magnetic field excitation; Set up the exciter field, provide exciting power to main frame magnetic field excitation generating usefulness again by exciter then.Therefore automatic voltage regulator (AVR) is an important composition part in this excitation system; In controlled excitation system, all need AVR; The quality of its quality not only directly influences the steady state voltage regulation and the dynamic characteristic of generator, and is related to the reliability and stability of whole generating system.Particularly brushless generator such as AVR break down, and the whole generating machine promptly can't generate electricity.
