Description
Technical field
The utility model relates to technical field of motors, in particular to a kind of cast-aluminum rotor.
Background technique
Cast-aluminum rotor is indispensable core component in motor, including rotor core made of being stacked as rotor punching with
And it is mounted on the aluminium ring of iron core two sides.
Existing rotor, which is generally taken, is arranged intensive closed slot on the sagittal plane on periphery on rotor punching to make
For mould in the mould of cast aluminium, so that technique is saved, but closed slot is too many, in motor high speed rotation, closed slot and windage
The wind noise of generation is quite big, causes noise of motor big, seriously affects the use feeling of user, while in motor operation, active
It is lost also big.
A kind of low-loss mouse cage cast aluminium rotor, this turn are disclosed in 104935134 A of Chinese invention patent specification CN
Son is stacked by rotor punching, and the jet-bedding on each rotor punching overlaps to form rotor slot, is inlaid with copper in the rotor slot
Conducting bar, the gap between copper conducting bar and rotor slot operate to form cast aluminium conducting bar by cast aluminium.The relatively traditional cast aluminium of the rotor turns
Son have lower resistivity and lower rotor active loss, compared with copper casting rotor simple process, facilitate realization industrialization.
But even if rotor slot number is still more, and due to rotor slot using this low-loss mouse cage cast aluminium rotor
Width it is typically small, copper conducting bar inlay wherein nor easily, due to having inlayed copper conducting bar, between copper conducting bar and rotor slot
Gap with regard to narrower, it will influence cast aluminium conducting bar quality, be easy to produce broken strip and slice and other issues.
Utility model content
For the above-mentioned prior art, the technical problem to be solved by the present invention is to provide one kind to have lower resistivity
With lower rotor active loss, and the cast-aluminum rotor of simple process, high yield rate.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution:
A kind of cast-aluminum rotor includes rotor core made of several rotor punchings stack and is mounted on rotor core both ends
Aluminium ring, the rotor punching are circle, and center offers shaft hole, offers keyway on the shaft hole, close to described
It is provided with 6-24 piece closed slot, 6-24 through-hole on the sagittal plane of rotor punching excircle, the through-hole rotor that is formed by stacking is logical
Hole, is inlaid with copper conducting bar in the rotor through-hole, and the closed slot is formed by stacking rotor jet-bedding, and the rotor jet-bedding cast aluminium is formed
Cast aluminium aluminum strip.
The closed slot is equal with the number of openings, interlaced arrangement, is evenly distributed on close to the rotor punching outer circle
On the sagittal plane in week.
The closed slot is 12, and the through-hole is 12.
Copper conducting bar both ends, which extend outwardly, is embedded in the aluminium ring.
Compared with prior art, the utility model has the advantages that for the stator core of motor: having lower
Resistivity and lower rotor active loss, improve yield rate, and simple process, improve efficiency.
Detailed description of the invention
Fig. 1 is the utility model cast-aluminum rotor structure cross-sectional view.
Fig. 2 is the structural schematic diagram of the utility model cast-aluminum rotor punching shown in Fig. 1.
Specific embodiment
Specific embodiment of the present utility model is further described in detail with reference to the accompanying drawing.
As depicted in figs. 1 and 2, the utility model cast-aluminum rotor includes rotor core 2 made of several rotor punchings 1 stack
With the aluminium ring 3 for being mounted on 2 both ends of rotor core.The rotor punching 1 is circle, and center offers shaft hole 101, described
Keyway 102 is offered on shaft hole 101,6-24 piece closed slot 103 is provided on the sagittal plane of excircle, and 6-24 logical
Hole 104, the closed slot are equal with the quantity of through-hole, it is preferable that the closed slot 103 be 12, through-hole 104 be 12 (such as
Shown in Fig. 2).The closed slot 103 and through-hole 104 are staggered, and are evenly distributed on the sagittal plane of excircle.It is described
Closed slot 103 is formed by stacking rotor jet-bedding, and the through-hole 104 is formed by stacking rotor through-hole.Copper is inlaid in the rotor through-hole
Conducting bar 4.Preferably, the rotor through-hole is round and ellipse.4 both ends of copper conducting bar, which extend outwardly, is embedded in rotor core 2
In the aluminium ring 3 at both ends.The rotor jet-bedding forms cast aluminium conducting bar by cast aluminium, can easily adjust cast aluminium conducting bar and copper conducting bar
Area ratio decrease to realize the balance of resistivity and material cost, while the enough cast aluminiums of width of rotor punching
Rejection rate decreases process time due to closed slot negligible amounts, improves efficiency.
Obviously, above-described embodiment is just for the sake of clearly demonstrating example, and does not limit the embodiments.
For those of ordinary skill in the art, other various forms of variations can also be made on the basis of the above description
Or it changes.There is no need and unable to be exhaustive to all embodiments.And the obvious variation thus amplified out
Or it changes among the protection scope created still in the utility model.
