Abstract

The utility model discloses an automobile magneto rotor. Even number of strip-shaped permanent magnets are uniformly and orderly ranged, the permanent magnets are fixedly connected with polar palms and magnetic conductors by dovetail grooves, dovetail flanges or cryptomorphic non-magnetic conducting screw nails to form even number of magnetic poles and the same even number of ventilating slots, the magnetic poles are uniformly provided with N poles and S poles arranged in interphase mode, and the dovetail grooves, the dovetail flanges or the cryptomorphic non-magnetic conducting screw nails are mutually matched by tolerance clearances. A core body which is filled with non-magnetic material is respectively used as a connecting part between a main shaft and magnetic conductors, and is used for positioning the magnetic conductors and the main shaft. The utility model has the advantages of reasonable and simple structure, easy assembly, small volume, light weight, high utilization rate of the magnetic remanence of the permanent magnets, good ventilating and heat dispersing performances, stable and reliable overall engine performance, and long service life.

Description

A kind of rotor of permanent magnetic generator for vehicle
The utility model relates to a kind of improvement of permanent magnetic generator for vehicle rotor, and this generator both can use with automobile, tractor, also can be used as Blast Furnace Top Gas Recovery Turbine Unit (TRT) and used.
Along with the development of permanent magnetic material is constantly goed deep into, the permanent magnetic material of various high remanent magnetism emerges in large numbers in succession and obtains practical application, make the permanent magnet generator performance that major improvement arranged, therefore there are many technical literatures to refer to, we also once proposed improvement project to this, see Chinese patent CN for details No. 952237938 " a kind of permanent magnetic generator for vehicle ", the p-m rotor of this generator has structurally been done certain improvement, the ventilation and heat performance is improved, the complete machine performance is more stable, but because the strip permanent magnet of rotor is to be inlaid in the embedding mouth of magnetic conductor, make the leakage of part magnetic energy, thereby reduced effective magnetic energy utilization rate of permanent magnet.
Task of the present utility model is the rotor that a kind of permanent magnetic generator for vehicle of new structure will be provided, and it is simple and reasonable for structure, and assembling is easy, and radiating condition is good, remanent magnetism utilance height, and machine volume is little, and is in light weight, stable performance, reliable, long service life.
Task of the present utility model is finished in such a way, the even number root strip permanent magnet of this rotor distributes equably, its arrangement is orderly, be connected and fixed with dovetail groove, dovetail flange or stealthy non-magnetic conduction screw between it and the utmost point palm, the magnetic conductor, they are evenly arranged into the ventilation slot of alternate even number of poles of N, S and similar number, the front end air inducing fan blade of non-magnetizer and rear end guiding fan blade adopt bolt, nut to be connected and fixed, and guiding fan blade and air inducing fan blade are corresponding one by one with ventilation slot.The permanent magnetic generator for vehicle that adopts this rotor to make, the magnetic energy of its permanent magnet is fully used, and the performance of ventilating between external stator and the rotor is good, can improve the power output of generator effectively.
Below in conjunction with accompanying drawing the utility model is further elaborated.
Fig. 1 is the cutaway view of permanent magnetic generator for vehicle rotor of the present utility model.
As can be seen from Figure, this novel permanent magnetic generator for vehicle rotor is by the permanent magnet (1) of even number root bar shaped evenly, arrange in an orderly manner, they are the dovetail groove (4) that cooperates with tolerance clearance, the ventilation slot (6) that dovetail flange (5) was connected and fixed and formed alternate even number of poles of the uniform N of being arranged as, S and similar number with the utmost point palm (2), magnetic conductor (3), and dovetail groove (4) is connected alternative with the non-magnetic conduction screw of the also available stealth of dovetail flange (5) syndeton.The strip permanent magnet (1) that this even number root is become by the rare earth permanent-magnetic material machined surface on magnetic conductor (3) outer ring circumference be according to Tactic.Between magnetic conductor (3) and main shaft (7) be the high-intensity non-magnetic conductive core of perfusion (8) connect and the relative position that keeps them on same axis.The front end air inducing fan blade (9) and the rear end guiding fan blade (10) of non-magnetizer are installed in the rotor both sides, their fan blade is corresponding with the number and the position of ventilation slot (6), is connected and fixed by bolt (11) and clamp nut (12) between front end air inducing fan blade (9) and the rear end guiding fan blade (10).The permanent magnet magnetic energy of this rotor obtains utilizing more fully, and circulation, the eddy current loss of magnetic circuit are little, thereby improves the power generation performance of complete machine effectively.This rotor simple in structure, the ventilation and heat condition is good, and machine volume is little, and is in light weight, and performance is good, long service life.

Claims (2)

1, a kind of by permanent magnet (1), magnetic conductor (3), the permanent magnetic generator for vehicle rotor that main shaft (7) etc. is formed, it is characterized in that: even number root strip permanent magnet (1) is even, arrange in an orderly manner, they and the utmost point are slapped (2), magnetic conductor (3) is the dovetail groove (4) that cooperates with tolerance clearance, dovetail flange (5) is connected and fixed and forms the uniform N of being arranged as, even number of poles that S is alternate and the ventilation slot of similar number (6), the relative position that is connected by the core body (8) of the non-magnetic conduction of perfusion between magnetic conductor (3) and the main shaft (9) and keeps them is on same axis, the both ends of the surface of rotor are equipped with the guiding fan blade (9) and the air inducing fan blade (10) of non-magnetizer respectively, their fan blade is corresponding with ventilation slot (6), and the guiding fan blade (9) of two ends and air inducing fan blade (10) are connected and fixed by bolt (11) and nut (12).
2, by the permanent magnetic generator for vehicle rotor of claim 1 defined, it is characterized in that: dovetail groove (4) and the non-magnetic conduction screw of the available stealth of dovetail flange (5) substitute.
