Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment one:
As shown in Figure 1, the present embodiment provides a kind of rotor, including iron core 200 and aluminium core 100, it is arranged on the iron core 200
There is centre bore 202, multiple rotor slots 201 are provided with around the centre bore 202, the aluminium core 100 is set to the multiple turn
In the pilot trench 201 and both ends of the iron core 200.
In this specific embodiment, as shown in Figs. 1-5, the iron core 200 includes multiple rotor sheets being sequentially overlapped.It is described
Rotor sheet is evenly arranged with multiple 201 holes of rotor slot the middle part is provided with a through-hole for disc structure around the through-hole.
Positioning region 203 is provided between 201 hole of rotor slot and the through-hole.The positioning region 203 includes four and is uniformly arranged
Punching press blind hole, punching press blind hole side are depressed in the surface of the rotor sheet side, and it is another that the other side protrudes from the rotor sheet
The surface of side.The cross section of the punching press blind hole is isosceles trapezoid.The iron core 200 includes two kinds of rotor sheets, the first institute
It states and is provided with first shaft hole in the middle part of rotor sheet, be provided with the second axis hole in the middle part of second of rotor sheet, the first shaft hole
Diameter is greater than the diameter of second axis hole, and 200 side of iron core is the first the multiple described rotor sheet being sequentially overlapped, separately
Side is multiple second rotor sheets being sequentially overlapped.There is an angle between the rotor slot 201 and vertical direction.Institute
Stating angle is 8 degree.The aluminium core 100 is fixed with the iron core 200 by the way of casting.
Rotor sheet is punched using silicon steel sheet, is sequentially overlapped after punching shaping, make in additive process adjacent rotor piece it
Between circumferentially turn an angle, make to be formed the angle between the rotor slot being finally formed by stacking 201 and vertical direction, by
