Abstract
The invention relates to a copper induction motor. The copper induction motor comprises a shell, a stator and a rotor, and is characterized in that the rotor is formed by casting a copper material under low pressure. By the copper induction motor obtained by the invention, the conventional aluminum material is replaced by the copper material; and the electric conductivity of copper is about 1.5 times that of aluminum. Therefore, the size can be greatly reduced under the same power by comparing the induction motor which adopts a copper rotor with the induction motor which adopts an aluminum rotor in the prior art; the material of the matched parts can also be saved in the situation; and therefore, the cost of the motor is reduced. In addition, the problems in a production process are also taken into consideration; the low-pressure casting process is designed and used, so that the phenomenon that notch connection wires are excessive because a high melting point of the copper is higher than that of aluminum can be prevented; the product quality is reduced; and the surface damage and the cursor loss of a product can also be reduced. In conclusion, the copper induction motor obtained by the invention has the characteristics of high performance, convenience in production and low cost.
Description
Technical field
The present invention relates to a kind of motor, particularly a kind of copper inducible motor.
Background technology
The rotor of motor of the prior art generally consists of by aluminum.Along with the progress of society, people are more and more higher to the requirement of motor, and requiring provides enough large power under the little volume of trying one's best.But because the restriction of technology and the characteristics of material own, the motor of aluminum rotor has been run into bottleneck in this, can't occur significantly improving again.
Summary of the invention
The objective of the invention is provides a kind of volume little for the deficiency that solves above-mentioned technology, but the large copper inducible motor of power output.
In order to achieve the above object, the copper inducible motor that the present invention is designed comprises housing, stator and rotor, it is characterized in that described rotor is made of by low pressure casting copper product.
The resulting copper inducible motor of the present invention, substitute existing aluminum by copper product, the conductance of copper is about 1.5 times of aluminium, hence one can see that, compare with the aluminium rotor electric machine of prior art as the rotor of inducing motor with copper, the equal-wattage lower volume can significantly be dwindled, and also can save in this case the material of kit, thereby reduces the cost of motor.The present invention has also considered the problem in the production process in addition, and low pressure casting process is used in design, prevents because the fusing point of copper is higher than aluminium so that too much notch connecting line occurs, so that the quality of product reduces, also can reduce product surface damage and vernier and decrease.In sum, the resulting copper inducible motor of the present invention has performance high, and is convenient for production, the characteristics that cost is low.
Embodiment
The present invention is further described by the following embodiment.
Embodiment 1:
The designed copper inducible motor of invention that the present embodiment is described comprises housing, stator and rotor, and wherein said rotor is made of by low pressure casting copper product.
Claims (1)
1. a copper inducible motor comprises housing, stator and rotor, it is characterized in that described rotor is made of by low pressure casting copper product.
