Abstract

The invention provides a generator device of a wind driven generator, which comprises a rotor, a stator and a driving device and is characterized in that a field winding and a main power generation winding are adopted, the field winding of the main generator is arranged on the rotor, the armature winding of the main generator is arranged on the stator (to output generated electricity), the armature winding of an exciter is arranged on the rotor, the field winding is arranged on the stator, a small-sized Ru ferroboron magnet is arranged on the outer layer of the mixed generator to provide energy for the field winding, all problems caused by the electric brush and the slip ring do not exist because of no electric brush and slip ring, no additional gap exists in a magnetic circuit, and the magnetic leakage is small.

Description

Alternating current generator
Technical field
The present invention relates to a kind of rotor machine, especially a kind of rotor machine of wind-driven generator.
Background technology
Generator is usually by stator, rotor, parts such as end cap and bearing constitute, stator is by stator core, line holds group, support and other structural members compositions of fixing these parts, rotor is by rotor core (or magnetic pole, magnetic is gripped) winding, retaining ring, centering ring, slip ring, parts such as fan and rotating shaft are formed, by bearing and end cap stator with generator, rotor assembles, rotor can be rotated in stator, do the motion of cutting magnetic line, thereby generation induced potential, draw by binding post, be connected in the loop, just produced electric current, turbo generator, it is the supporting generator of steam turbine, in order to obtain higher efficient, steam turbine is generally made at a high speed, is generally 3000 rev/mins (frequency is 50 hertz) or 3600 rev/mins (frequency is 60 hertz).Turbine speed is lower in the nuclear power station, but also more than 1500 rev/mins, the high speed turbo generator is in order to reduce the mechanical stress that produces because of centrifugal force and to reduce the wind abrasion, root diameter is generally done smallerly, length is bigger, promptly adopt elongated rotor, requirement to material is very high, wanting to increase generator capacity after rotor size arrives certain limit has only to check by the electromagnetism that increases generator and realizes again, the caloric value that can increase generator so greatly reduces efficiency of motor, but also must carry out passive cooling to generator, and having improved the production and the maintenance cost of motor, the brush of generator also will be changed troublesome maintenance and cost height.
Summary of the invention
The present invention is directed to the defective of prior art, a kind of gen-set device of practicality is provided.
To achieve these goals, the present invention takes following measure to realize:
A kind of rotor machine of wind-driven generator, comprise rotor, stator, drive unit is characterized in that adopting excitation winding and main generating winding, and the excitation winding of main generator is at rotor, armature winding is in stator (the electricity output that will send), the armature winding of exciter is at rotor, and excitation winding is at stator, and skin is provided with small-sized Ru-Fe-Mn magnet provides energy for excitation winding mixed type generator.
The present invention has following characteristics with respect to prior art: so the present invention owing to all problems that does not have brush and slip ring not to exist brush and slip ring to cause, does not have additional crack in the magnetic circuit, the little power output of leakage field is big.
Embodiment
The present invention adopts double-generator, provide excitation to the excitation winding of exciter on stator, its armature rotor winding will send alternating current, behind over commutation, power in the excitation winding of rotor to main generator, thereby make main generator induce required alternating current at the armature winding of stator at rotor.
In the practical application, also can adopt the dual formula windmill, with the long generator in little windmill of stablizing windmill as excitation winding power since basic the maintenance synchronously can realize bigger energy output.
In the application, the present invention is applied in the power station, and its heating property is higher by 20% than general.
