Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model rotor lamination of generator.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment rotor lamination of generator, comprise lamellar body 1, the axis hole 2 coordinated with engine rotor axle is provided with in the middle part of described lamellar body 1, described lamellar body is provided with the rectangular permanent magnet installing hole 3 that two composition axial symmetry are arranged, often organize permanent magnet installing hole and comprise two permanent magnet installing holes becoming splayeds to arrange, and two permanent magnet installing holes often in group be provided with connectivity slot 4 closest between two rectangle bights.
The present embodiment rotor lamination of generator, it by arranging permanent magnet installing hole on lamellar body, on rotor core permanent magnet can being directly inserted into be made up of punching, quick and easy for installation, can improve the production efficiency of generator.And two permanent magnet installing holes be provided with connectivity slot closest between two rectangle bights, make the bight magnetic power of permanent magnet more evenly enter iron core, magnetic field homogeneity and generating efficiency can be improved.
The improvement of the present embodiment of opposing, lamellar body between two permanent magnet installing hole ends in each group is also provided with radiating groove 5, radiating groove 5 can improve generator amature radiating efficiency, the generator life-span can be improved, louvre can make adjacent magnetic field boundary line more clear simultaneously, reduce output harmonic wave, be conducive to improving generator operation efficiency.
As the improvement to the present embodiment, lamellar body between two groups of permanent magnet installing holes is also provided with two Baltimore grooves 6 becoming axial symmetry to arrange, the bottom of described Baltimore groove is provided with triangular hill 7, Baltimore groove and triangular structure can make adjacent magnetic field boundary more clear, and the better linear distribution of magnetic field energy can be made, reduce harmonic losses, be conducive to improving engine operating efficiency.
As the improvement to the present embodiment, lamellar body between two Baltimore grooves is provided with bolt through-hole 8, in bolt through-hole, penetrate bolt can be fixedly connected with integrally by each punching forming rotor core, rotor punching is connected compared to adopting bonding way in prior art, it installs more convenient and quicker, and bonding strength is higher.
For the rotor punching of 6Kw generator, it is 98.6mm that lamination structure is preferably external diameter, and the diameter of axis hole 2 is 32mm, and the length of permanent magnet installing hole 3 is 38mm, and wide is 17.5mm, and the groove width of Baltimore groove 6 is 28mm, and groove depth is 6mm.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
