Abstract
The utility model relates to a pole shoe iron core device for a tilting magnet pole of a wind generator, which is characterized by comprising a first pole body, a second pole body, a first pole shoe, a second pole shoe and a magnet pole pin, wherein, the first pole shoe and the second are respectively fixed on the first pole body and the second pole body and are connected with each other to form a large-angle V-shaped structure; and the magnet pole pin penetrates the first pole body and the second pole body and is fixed by a bolt. The pole shoe iron core device provided by the utility model has lower demand on installation precision and less difficulty in installation, is convenient to install; besides a rotor provided by the utility model can effectively prevent harmonic waves, thereby lowering noise, reducing the redundant heat, and further prolonging the service life of the rotor.
Description
Technical field
The utility model relate to a kind of wind-driven generator tilting magnetic pole pole shoe core device that is exclusively used in.
Background technology
Design and installation has stator and rotor in the wind-driven generator, and the magnetic pole pole shoe is installed on rotor, and the energy of wind makes the rotor rotation realize wind, electric energy conversion.Because 2MW electricity excitation direct-drive aerogenerator rotor and magnetic pole pole shoe core length are longer; The design of prior art rotor magnetic pole pole shoe is that integral type is straight shape; Its defective is: the location and installation difficulty that integral type is straight shape magnetic pole pole shoe is big; As the gap deviation occurs and can cause rotor in rotary course, to make a noise, produce heat, influence useful life.
The utility model content
The purpose of the utility model is to overcome the above-mentioned deficiency that exists in the prior art, and a kind of reasonable in design is provided, and can reduce a kind of wind-driven generator tilting magnetic pole pole shoe core device of harmonic wave.
The utility model addresses the above problem the technical scheme that is adopted: a kind of wind-driven generator tilting magnetic pole pole shoe core device; It is characterized in that: comprise first pole body, second pole body, first pole shoe, second pole shoe and magnetic pole pin; Said first pole shoe is fixed on first pole body; Said second pole shoe is fixed on second pole body, and said first pole shoe links to each other with the V font structure that second pole shoe is wide-angle, and said magnetic pole pin passes first pole body and second pole body and uses bolt.Make that rotor air gap between stator and the rotor in rotation process is even, can effectively prevent the generation of harmonic wave.
The utility model compared with prior art has the following advantages and effect: the installation accuracy of wind-driven generator tilting magnetic pole pole shoe core device requires lowly in the utility model, and installation difficulty is low, the convenient installation.And the utility model rotor can also effectively prevent the generation of harmonic wave, thereby reduces the generation of noise and unnecessary heat, the useful life of improving the utility model rotor.

Embodiment
Below in conjunction with accompanying drawing and through embodiment the utility model is done further to specify, following examples are to the explanation of the utility model and the utility model is not limited to following examples.
Referring to Fig. 1-Fig. 4; Wind-driven generator tilting magnetic pole pole shoe core device in the present embodiment is called for short pole shoe core device 2; Pole shoe core device 2 is installed on the rotor subject 1, and pole shoe core device 2 comprises first pole body 211, second pole body 212, first pole shoe 22, second pole shoe 23 and magnetic pole pin 24.Be rotor 3 between two pole shoe core devices 2 on the rotor subject 1 in the present embodiment.First pole body 211 and second pole body 212 are referred to as pole body 21.
Promise is done a pole shoe core device 2 and evenly is fixed on the outer surface of rotor subject 1.Pole body 21 is fixed on the rotor subject 1, and first pole shoe 22 and second pole shoe 23 connect to form the V font structure of wide-angle, and this structure is fixed on the pole body 21.
When the rotor in the present embodiment uses, rotor rotation.Stator slot on the generator unit stator and pole body 21 parallel, and first pole shoe 22 and second pole shoe 23 connect to form the V font structure of wide-angle and be fixed on the pole body 21, make the intersecting of this V font structure and stator slot; Be to stagger on the time and space; Air gap between rotor is even relatively, has greatly weakened harmonic field, has reduced vibration and noise; Avoid and reduced rotor heat that produces in rotary course, prolong wind-driven generator useful life.
Above content described in this specification only is to be illustrated what the utility model structure did.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; Only otherwise depart from the structure of the utility model or surmount the defined scope of these claims, all should belong to the protection range of the utility model.
