Abstract
The utility model relates to a rotor of a high-efficiency and ultra high-efficiency three-phase asynchronous motor, which comprises a rotor iron core, two cast aluminum end rings arranged on the ends of the rotor iron core and a plurality of blades arranged on the outer end surfaces of the two cast aluminum eng rings, and is characterized in that the plurality of the blades are uniformly distributed on the outer end surfaces of both ends of the cast aluminum end rings, and each blade is in a spiral arc shape. After the technical scheme is adopted, the wind force and the wind volume produced by the blades when the rotor rotates are improved compared with the blades of a traditional motor, the flowing direction of cooling air becomes more reasonable, the axial and radial flowing wind volume of the rotor is increased under the circumstance of not increasing the size and the cost, the cooling effect of the three-phase asynchronous motor is effectively improved, the temperature rise of the high-efficiency and ultra high-efficiency three-phase asynchronous motor can be reduced by more than 3 percent, so as to improve the electric performance and prolong the service life of the motor.
Description
Technical field
The utility model relates to the motor technology field, is specifically related to a kind of rotor of efficient, ultra high efficiency threephase asynchronous.
Background technology
The use of motor is quite general in daily life, and people are also constantly improving and improving the manufacturing process of motor performance and motor according to the difference of use occasion simultaneously.
In the rotor manufacturing process of original traditional threephase asynchronous, what adopt is to be provided with radially fan blade on the both ends of the surface of casting aluminum rotor end ring, and radially fan blade is generally linear, utilizes the rotor rotation of motor, produce the footpath aweather, reach the effect that makes the motor cooling.
Because radially the air quantity of fan blade generation is very little, cooling airflow is to not being quite reasonable, and is lower to the effect of motor cooling, and the power output that influences motor improves, and is unfavorable to the insulating material in the motor, thereby shortens the useful life of motor.
How improving this defective, improve the useful life of motor, is that motor manufacturing technical staff will constantly make great efforts the direction studied.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of rotor of efficient, ultra high efficiency threephase asynchronous, improve the cooling effect of threephase asynchronous effectively, thereby improved its electric property, reach the useful life that prolongs motor.
A kind of technical scheme that realizes above-mentioned purpose is: a kind of rotor of efficient, ultra high efficiency threephase asynchronous, comprise that rotor core, two are in the cast aluminium end ring at rotor core two ends, some fan blades that is in two cast aluminium end ring outer faces, described some fan blades are evenly distributed on the outer face at described cast aluminium end ring two ends, and the equal arcuation in the shape of a spiral of described each fan blade shape.
Described fan blade and cast aluminium end ring form for the cast aluminium casting with one.
Described fan blade also can be the parts that are fixed on the described cast aluminium end ring outer face.
Described rotor core has central shaft hole, to the formed annulus of internal diameter circumferential edge of described cast aluminium end ring, is uniform-distribution with several along the axial wind-guiding cooling through hole of rotor core in the circumferential edge of described axis hole.
After having adopted above-mentioned technical scheme, fan blade produces when making the rotor rotation wind-force and air quantity have had raising than the conventional electric machine blade, it is more reasonable that the flow direction of cooling air becomes, do not increasing under volume and the condition of cost, increased the air quantity of rotor axial and Radial Flow, effectively raise the cooling effect of this threephase asynchronous, make temperature rise efficient, the ultra high efficiency threephase asynchronous can descend more than 3%, thereby improved its electric property, reached the useful life that prolongs motor.

Embodiment
In order to understand the technical solution of the utility model better, below by specific embodiment and Fig. 1, Fig. 2, Fig. 3 in conjunction with the accompanying drawings be described in detail.
See also Fig. 1, Fig. 2 and Fig. 3, the rotor of a kind of efficient, ultra high efficiency threephase asynchronous of the present utility model, comprise that rotor core 3, two are in the cast aluminium end ring 2 at rotor core two ends, some fan blades 1 that is in two cast aluminium end ring outer faces, some fan blades 1 are evenly distributed on the outer face at described cast aluminium end ring 2 two ends, and the equal arcuation in the shape of a spiral of described each fan blade shape.
Fan blade 1 forms for the cast aluminium casting with one with cast aluminium end ring 2, and fan blade 1 also can be the parts that are fixed on cast aluminium end ring 2 outer faces.
Rotor core have a central shaft hole 5, in the circumferential edge of described axis hole 5 to the formed annulus of internal diameter circumferential edge of described cast aluminium end ring 2, be uniform-distribution with several and cool off through hole 4 along rotor core 3 axial wind-guidings, the axial cooling wind energy that makes fan blade 1 produce is cooled off by 4 pairs of rotor cores 3 of wind-guiding cooling through hole.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
