Abstract
The utility model discloses a rotor of a rare earth permanent magnet generator. The rotor has a structure that two pairs of magnetic poles of permanent magnets and magnetic poles of soft magnets are fixed on a rotor iron core, wherein one half of the poles is the magnetic poles of the permanent magnets having the same polarity, the other half is the magnetic poles of the soft magnets, the magnetic poles of the permanent magnets and the magnetic poles of the soft magnets are arranged in an interposed manner, and a magnetic insulating body with a length longer than that of air gaps is added between every two magnetic poles to reduce the magnetic flux leakage.
Description
Technical field:
The utility model is a kind of structure member of small power generator, cooperate with generator unit stator through power drive give few electricity, have a power failure, the situation such as emergent, field construction provides electric energy.
Background technology:
Rare earth permanent-magnetic generator is because the advantage such as the high and use cost of efficient is low, more and more be subjected to user's favor, occupation rate of market is soaring rapidly, but in recent years, the rare earth market price is day by day surging, this makes the manufacturing cost of rare earth permanent-magnetic generator seem very high, to such an extent as to there is the part user to bear.
Summary of the invention:
In order to reduce the manufacturing cost of rare earth permanent-magnetic generator, the rotor of a kind of rare earth permanent-magnetic generator that the utility model provides, change 2 pairs of permanent magnet poles of former rare-earth permanent magnet generator rotor into 1 pair of permanent magnet pole and 1 pair of soft magnetic bodies magnetic pole, it is that raw material are made that permanent magnet pole adopts rare earth, and soft magnetic bodies adopts general permeability magnetic material, compare with former rare earth permanent-magnetic generator, can reduce by 50% rare earth materials.The utility model discloses a kind of rotor of rare earth permanent-magnetic generator, fixed 1 pair of permanent magnet pole and 1 pair of soft magnetic bodies magnetic pole at rotor core, permanent magnet pole is connected with bolt with rotor core with the soft magnetic bodies magnetic pole.It is characterized in that: utilize 1 pair of same sex permanent magnet pole and 1 pair of soft magnetic bodies magnetic pole to interleave every magnetic patch to reduce leakage field at rotor core.
Permanent magnet pole of the present utility model and soft magnetic bodies magnetic pole are installed in the rotor core surface, rotor consists of hidden pole type, the direction of magnetization of permanent magnet pole and soft magnetic bodies magnetic pole and the radius of rotor are quadratures, i.e. tangential direction, and the magnetic circuit of adjacent two magnets of tangential structure is in parallel.
Because the utility model has been saved the rare earth permanent-magnetic material consumption of half on the basis of conventional structure, cost is reduced greatly.
Description of drawings:
Fig. 1 is the utility model rare-earth permanent magnet generator rotor structural representation.
Fig. 2 is the utility model rare-earth permanent magnet rotor inner magnet line of force distribution schematic diagram.
Among the figure: 1, permanent magnet pole 2, every magnetic patch
3, soft magnetic bodies magnetic pole 4, rotor core
Embodiment:
In special positioning tool, the reliable fixed form of all permanent magnet poles 1 usefulness is fixed on the rotor core 4, after taking out with high strength glue all being fixed on rotor core 4 and the permanent magnet pole 1 every magnetic patch 2, and then at another special positioning tool all soft magnetic bodies magnetic poles 3 are fixed on the rotor core 4, like this, the utility model has just formed.
