Abstract
The utility model discloses a rotor assembly of a wind-driven power generator, which comprises a rotor and magnetic steel. The outer surface of the stator is provided with a plurality of punching sheets. The top end of each punching sheet is provided with a flange extending towards two sides, a groove is arranged at a central position of two sides of the magnetic steel, the punching sheets adopt materials of DW470 silicon steel blades, and the magnetic steel is made of neodymium iron boron. The rotor assembly is firm in fixing, good in overall performance, not prone to fall and convenient in installation, thereby meeting the requirement that the motor is reliable and stable in operation.
Description
Technical field
The utility model relates to a kind of wind power generator rotor assembly.
Background technology
Generator magnet steel former always being of rotor of packing into adopted the glue sticking type, magnet steel sticked with glue in certain sequence fixing, under guarantee of tooling, magnet steel is stained with and adheres to cylindrical unshakable in one's determination.In assembling process, because magnet steel magnetic is strong, it is not easy by integral body of desirable state and formation unshakable in one's determination, and the interaction between the similarities and differences utmost point brings inconvenience for operation.The shortcoming of this structure is complex process, operating difficulties.And after long-term the use, influence positioning accuracy, in addition in use, the temperature that produces along with the motor rotation reduces the glue reliability of being stained with sticking magnet steel, also make the magnet steel location produce random skew, thereby it is unbalance to influence the motor magnetic circuit.
The utility model content
The utility model technical problem to be solved provides a kind of design of New-type electric machine rotor punching, and its positioning magnetic steel precision is high, and then has improved the quality of motor.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is
A kind of wind power generator rotor assembly comprises rotor, magnet steel, and the outer surface of said rotor has a plurality of punchings, and the top of said each punching has the flange that extends to both sides, and the middle part, both sides of said magnet steel has groove.
Said punching material is the DW470 silicon steel sheet, and said magnet steel material is a neodymium iron boron.
The utility model rotor punching and common rotor punching profile are distinguished to some extent; It is sticking with directly being stained with of iron core to have changed original magnet steel, adopts punching tooth portion draw-in groove to fix with cooperating of magnet steel two ends groove, makes magnet steel be fixed on the iron core firmly; Fuse good integrity.
The utility model has the advantages that:
The utility model is fixed, makes its good integrity, be not easy to come off, and easy for installation, thus reach reliable, the stable requirement of motor.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing; A kind of wind power generator rotor assembly comprises rotor 1, magnet steel 2, and the outer surface of said rotor 1 has a plurality of punchings 3; The top of said each punching 3 has the flange 4 that extends to both sides; The middle part, both sides of said magnet steel 2 has groove 5, and said punching 3 materials are the DW470 silicon steel sheet, and said magnet steel 2 materials are neodymium iron boron.
