Abstract
The utility model discloses a low aluminum consumption motor rotor. The rotor comprises a rotor iron core overlapped by rotor punching sheets (1), wherein central holes (2) and locating holes (3) are arranged on the rotor punching sheets (1), 30 cast aluminum slots (4) are arranged on the rotor punching sheets along the circumference, and the cast aluminum slots (4) are opening slots. The low aluminum consumption motor rotor further reduces the cross section of the cast aluminum slots. Compared with the prior art, the low aluminum consumption motor rotor lowers the aluminum consumption, lowers the manufacture cost of the motor, and improves the economical benefits of enterprises through reducing the number of the cast aluminum slots and reducing the cross section of the cast aluminum slots under the condition that the overall performances of the motor basically accord with demands.
Description
Technical field
The utility model relates to a kind of motor, particularly relates to a kind of lower aluminum consumption machine rotor.
Background technology
At electric manufacturing, the manufacturing technology of motor is increasingly mature, and the overall dimension of various motors, performance index all have national standard.In order to improve the competitiveness of product in market, all under the situation that satisfies the motor key property, that does the best taps the potential of enterprises in each motor enterprise, does a lot of work on the saving motor cost, to improve economic benefit of enterprises.
Making on the rotor punching of rotor and all be provided with the cast aluminium groove that quantity does not wait, when making rotor, is that some rotor punchings are overlapped together, and is placed in the cast-aluminum die cast aluminum liquid in the cast aluminium groove, forms the rotor winding.Because the price of aluminium is more expensive, so save the consumption of aluminium, the cost of manufacture that can effectively save motor.Cast aluminium groove quantity on the rotor punching is too much at present, and the cast aluminium slot cross-section is excessive, and causing with the aluminium amount increases.
The utility model content
Goal of the invention of the present utility model is, a kind of lower aluminum consumption machine rotor is provided.The utility model can satisfy the basic demand of motor overall performance, can reduce the aluminium consumption again, reduces the manufacturing cost of motor, improves the business economic benefit.
The technical solution of the utility model: a kind of lower aluminum consumption machine rotor, this rotor comprises the rotor core that rotor punching laminates; Rotor punching is provided with centre bore and location hole, and rotor punching upper edge circumference is provided with 30 cast aluminium grooves; The cast aluminium groove is an open slot.
In the above-mentioned lower aluminum consumption machine rotor, described cast aluminium groove is a circular arc concentric reducer structure, large circular arc radius R=1.22mm, roundlet arc radius r=0.8mm, the centre-to-centre spacing L=19.88mm of orthodrome and little circular arc.
In the aforesaid lower aluminum consumption machine rotor, the orthodrome place on the described cast aluminium groove is provided with opening.
In the aforesaid lower aluminum consumption machine rotor, the width W=0.8mm of described opening.
Compared with prior art, the utility model is satisfying under the satisfactory substantially situation of motor overall performance, by reducing the cast aluminium groove quantity and the sectional area that reduces the cast aluminium groove on the rotor, to reduce the aluminium amount of using, reduce the manufacturing cost of motor, improved economic benefit of enterprises.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of cast aluminium groove.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.Following embodiment is a kind of of the preferred embodiment of the utility model, the utility model is not done any restriction.Common variation and replacement that those skilled in the art carries out in the technical solutions of the utility model scope all should be included in the protection range of the present utility model.
Embodiment: a kind of lower aluminum consumption machine rotor, as shown in Figure 1, it comprises the rotor core that rotor punching 1 laminates; Rotor punching 1 is provided with centre bore 2 and location hole 3.Rotor punching 1 upper edge circumference is provided with 30 cast aluminium grooves 4; Cast aluminium groove 4 is an open slot.The utility model is the improvement to existing rotor.Concrete improvement is to change 34 cast aluminium grooves on the existing rotor into 30, cross sectional shape to the cast aluminium groove improves simultaneously, cast aluminium groove after the improvement is a circular arc concentric reducer structure, large circular arc radius R=1.22mm, roundlet arc radius r=0.8mm, the centre-to-centre spacing L=19.88mm of orthodrome and little circular arc.Orthodrome place on the cast aluminium groove 4 is provided with opening 5.Width W=the 0.8mm of opening 5.Cast aluminium slot cross-section after the improvement is long-pending long-pending less than existing cast aluminium slot cross-section.Reduced and used the cast aluminium amount, reduced the manufacturing cost of motor, improved economic benefit of enterprises.
