Abstract
A non-brush synchronous generator of external rotor type for rotary exciter comprises a base, a main generator stator, a main generator rotor, a rotary exciter stator, a rotary exciter rotor, a rotary rectifier, an end cover and a bearing device, which is characterized in that the rotor of the rotary exciter is arranged at the outer side of the stator therefore. The non-brush synchronous generator has small volume and low weight, is suitable for the working field (as hydro generator) demanding large rotation inertia.
Description
Technical field
The utility model relates to a kind of no-brush synchronous generator, especially relates to the no-brush synchronous generator that a kind of rotating exciter adopts external-rotor-type.
Background technology
Present no-brush synchronous generator, its rotating exciter mostly is the inner-rotor-type structure, and just its armature rotates at interior circle, and its excitation field maintains static at cylindrical encirclement rotor.Just there is a kind of un-reasonable phenomenon in this: the power of armature portion is bigger, the power of excitation field less (generally have only the former about 3%) places the bigger armature of power on the less interior circle of size, and is not only unreasonable on the structure, volume and weight is big, and heat radiation is also relatively more difficult.
The utility model content
The purpose of this utility model is to overcome the above-mentioned defective that existing no-brush synchronous generator exists, and provides a kind of volume little, in light weight, and the rotating exciter of perfect heat-dissipating adopts the no-brush synchronous generator of external-rotor-type.
The technical solution of the utility model is: it comprises support, main generator unit stator, main generator rotor, exciter stator, exciter rotor, rotating rectifier, end cap, bearing arrangement, it is characterized in that, the rotor of rotating exciter is positioned at its stator outside, during operation, rotates around stator.
Main generator rotor can be a hidden pole type, or salient pole type.
The rotating excitation machine stator can be a hidden pole type, or salient pole type, also can be Lundell.
The utility model exciter rotor is in its stator outside, so be called the external-rotor-type exciter.
Advantage of the present utility model is: rotating exciter is than general inner-rotor-type more reasonable structure, and volume and weight is littler; When volume was identical, moment of inertia was bigger, more was applicable to the workplace (as hydraulic generator) that requires moment of inertia bigger; Because the armature winding of external rotor excitation-type is fixing more convenient, can be applicable to higher rotating speed; When the rotating excitation machine stator was made Lundell, volume size can be done forr a short time.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, present embodiment, similar to the no-brush synchronous generator of conventional known, comprise support 5, rotating shaft 1, main generator unit stator 6, main generator rotor 7, rotating excitation machine stator 3, rotating excitation machine rotor 4, rotating rectifier 8, end cap 2, fan 9, bearing arrangement 10, it is characterized in that, the armature rotor 4 of rotating exciter is positioned at its stator 3 outsides, during operation, rotates around stator.
Rotating excitation machine stator 3 is hidden pole types, or salient pole type, or Lundell.
The utility model operation principle is identical with existing no-brush synchronous generator.
