Automobile magneto rotor

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.
