Abstract
The invention discloses a copper conducting bar rotor which comprises aluminum end rings, copper conducting bars and a rotor punching body, and is characterized in that a plurality of copper conducting bars are uniformly distributed and inserted into the rotor punching body, and the plurality of the copper conducting bars are wrapped by the aluminum end rings. The length of the copper conducting bars is greater than that of a rotor punching, and a groove is arranged on each copper conducting bar. In the invention, aluminum conducting bars are replaced by the copper conducting bars, thereby not only greatly lowering the cost of equipment, a die and a motor, but also improving the efficiency of the motor and enabling the energy efficiency standard of the motor to achieve or exceed the grade 2 efficiency standard.
Description
Technical field
The present invention relates to a kind of copper sliver rotor, specifically when casting aluminum rotor, replace present aluminium sliver, thereby improve efficiency of motor with the copper sliver.
Background technology
The electric efficiency major part of China's middle and small motor industry production is three stage efficiencies at present; Enforcement along with national energy-saving and emission-reduction measure; The electric efficiency of electromechanics trade will be brought up to two stage efficiencies; Stray loss in the electrical type tests also will adopt measurement method simultaneously, rather than the method for the Power x 5 ‰ that adopts at present.Given this plant situation, in the motor of seat No. below 132, the motor that rotor adopts aluminium sliver technology to make is difficult to satisfy this efficient requirement.
In prior art, the rotor processing technology is after several rotor punchings are built up certain altitude, to put into mould, and the aluminium after the fusing is poured into, and die casting forms on die casting machine, so be referred to as cast-aluminum rotor.Cast-aluminum rotor is made up of rotor punching, aluminium sliver and aluminium end ring, and the rotation of motor is to be produced by several aluminium slivers of rotating magnetic field cutting that exchange to change, so that sliver plays a part in motor is very important.As adopt cast copper, and because the fusing point of copper is high more a lot of than the fusing point of aluminium, die casting machine and mould need bear the influence of very high temperature to its generation, this has just caused the high of equipment and mold cost, simultaneously the cost of motor is increased greatly.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of copper sliver rotor is provided, can reduce the cost of equipment, mould and motor greatly, can improve efficiency of motor, make the efficiency standard of motor meet or exceed the secondary efficiency standard.
According to technical scheme provided by the invention, a kind of copper sliver rotor comprises aluminium end ring, copper sliver, rotor punching body, and characteristic is: some copper slivers are uniformly distributed with and insert in the rotor punching body, and said some copper slivers are carried out by aluminium end ring bag.
As further improvement of the present invention, the length of said copper sliver is longer than rotor punching length, has a groove on the said copper sliver.
Compared with present technology the present invention has the following advantages:
The present invention replaces the aluminium sliver with the copper sliver, not only greatly reduce the cost of equipment, mould and motor, has also improved efficiency of motor, makes the efficiency standard of motor meet or exceed the secondary efficiency standard.
Description of drawings
Fig. 1 is a rotor structure front view of the present invention.
Fig. 2 is a rotor structure left view of the present invention.
Fig. 3 is a copper sliver structural representation of the present invention.
Embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe.
Like Fig. 1～shown in Figure 3, comprise aluminium end ring 1, copper sliver 2, rotor punching body 3.
According to the rotor punching slotted shape, make a mould, mould is installed on the copper material drawing machine, pull into the copper sliver 2 of certain-length, the length of copper sliver 2 is more longer than rotor punching length, on copper sliver 2, has a little long recess.Rotor punching is built up the rotor punching body of certain altitude, utilize automatic slot machine that some copper slivers 2 are uniformly distributed with and insert in the rotor punching body 3, the rotor punching body 3 of inserting good copper sliver is placed on the die casting machine, the aluminium after melting is poured into, die casting copper sliver rotor.
Aluminium after gap between copper sliver of the present invention and the rotor punching flute profile, the groove on the copper sliver all are melted fills up, the mechanical strength when having guaranteed the motor rotation.
The present invention has overcome defective in the rotor cast copper, has reduced the manufacturing cost of equipment and motor, has also improved electric efficiency simultaneously, is that a kind of novel cast aluminium adds the copper hybrid technique.Because the copper resistance rate is littler than aluminium resistivity, corresponding loss is also much lower than aluminium loss, adopts the copper sliver to replace the aluminium sliver to address this problem well in the rotor.
Claims (3)
1. a copper sliver rotor comprises aluminium end ring (1), copper sliver (2), rotor punching body (3), it is characterized in that: some copper slivers (2) are uniformly distributed with and insert in the rotor punching body (3), and said some copper slivers (2) are carried out by aluminium end ring (1) bag.
