Abstract

The invention provides a brushless generator without an automatic voltage regulator (AVR). The brushless generator comprises a main unit and an exciter. The main unit comprises a main unit rotor pole lamination. The exciter comprises an exciter stator pole lamination. The main unit rotor pole lamination is symmetrically provided with four permanent magnets. A non-salient pole rotating-armature mode is adopted for the magnetic circuit structure of the exciter stator pole lamination, and a magnetic field winding of the exciter is a three-phase magnetic field winding. The brushless generator is not provided with the AVR, so that cost is reduced, economic benefits are improved, the maintenance of the generator is facilitated, and a failure rate is decreased. 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 [0001] The invention relates to a generator structure, in particular to a brushless generator without a voltage regulator. Background technique [0002] Generally, the traditional brushless generator must be equipped with an automatic voltage regulator (AVR). One of its working principles is to control the excitation power provided by the main winding (or auxiliary winding) of the generator to keep the generator terminal voltage constant; The second is the voltage induced by the main winding (or auxiliary winding) of the generator from the air-gap residual magnetic field. After being rectified by the voltage regulator (AVR), the excitation power is provided to excite the stator magnetic field of the exciter to establish the magnetic field of the exciter, and then the excitation The generator then provides excitation power to the host for magnetic field excitation and power generation. Therefore, the automatic voltage regulator (AVR) is an important part of t...
