Abstract
The utility model relates to an efficient unobstructed permanent magnet wind generator. The wind generator comprises a stator and a rotor, permanent magnet magnetic steels (1) are spaced tile-shaped, press iron wedges (2) are arranged among the permanent magnet magnetic steels (1) and are fixedly mounted on a rotor main body (4) through bolts (3), and the permanent magnet magnetic steels (1) and the press iron wedges (2) are in tight fit. The permanent magnet magnetic steel has easily manufactured structure and high utilization ratio, is convenient to mount and can reduce magnetic leakage; the press iron wedges are arranged among the permanent magnet magnetic steels, so that not only the installation of the magnetic steel is firm, but also the distribution of magnetic circuit is uniform and the generator start is facilitated; end pads can play a role of protecting the magnetic steels, so as to avoid magnetic leakage, make the magnetic field distribution to be uniform, and facilitate generator start; and spacing pads can reduce electromagnetic forces among the magnetic steels in the same level at the same time.
Description
Technical field
The utility model relates to a kind of permanent magnet generator, particularly a kind of efficient without hindrance formula permanent magnet generator that is applied to the wind power generation industry.
Background technology
Existing permanent magnet generator generally is made of rotor and stator, and the permanent magnetic steel in the rotor is that the cross section is the magnet steel of rectangle, has bigger leakage field between the magnet steel stator, thereby has influenced effective output of permanent magnet generator acc power, and energy conversion rate is lower.And existing magnet steel direct fixed processing hole on magnet steel mostly, but difficulty is manufactured in the processing of this magnet steel with holes, and broken easily, cause waste aborning.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and the permanent-magnetic wind driven generator that a kind of leakage field is little, power output is big is provided.
The technical solution of the utility model is: a kind of efficient without hindrance formula permanent-magnetic wind driven generator, constitute by stator and rotor, described permanent magnetic steel is a watt shape at interval, be provided with between the permanent magnetic steel and compress drift, permanent magnetic steel and compressing between the drift closely cooperates, and the dog wedge Tie Tong crosses bolt and is installed on the rotor body.
Preferably: the waist of described permanent magnetic steel is provided with groove, and the waist that compresses drift is provided with the boss with groove fit.
Preferably: the waist of described permanent magnetic steel is provided with boss, and the waist that compresses drift is provided with the groove that cooperates with boss.
Preferably: described rotor is set to internal rotor, and the rotor body of internal rotor is provided with air vent hole.
Preferably: described rotor is set to external rotor.
Preferably: described rotor is provided with at least one row, and the two ends of rotor are provided with end pad, arranges more and is provided with dottle pin between the rotor.
Preferably: described stator is that stator is whole apart from the chain type winding.
The beneficial effects of the utility model are: the structure of the utility model permanent magnetic steel is made easily; the utilance height is convenient to install and can reduce leakage field, is provided with between the permanent magnetic steel and compresses drift; it is fastening not only to make magnet steel install; simultaneously magnetic circuit is evenly distributed, helps the startup of generator, the end pad also can play the protection magnet steel; prevent leakage field; make Distribution of Magnetic Field even, help the effect that generator starts, dottle pin can alleviate the electromagnetic force between the magnet steel at the same level.The utility model can be used for inner and outer rotors, and is applied widely, and rotor is provided with. air vent hole, help heat radiation, and can weight reduction save material simultaneously, raise the efficiency.Generator unit stator is whole to roll off the production line simply apart from the chain type winding, and coil size is identical, and span is identical; Concentrate winding, compact conformation, induced voltage height; , inner no circulation, loss is low; . number of poles is many, and rotating speed is low, is applicable to direct-drive aerogenerator; Save speed increasing mechanism, simple in structure, failure rate is low, the efficient height.
