Abstract
The utility model relates to a kind of rotor and motor, this rotor comprise some be arranged in order the iron core of setting, the some rotor bars be embedded in iron core, be arranged on described iron core two ends and connect adjacent rotor sliver end ring, be clamped in interior partition between two adjacent iron cores, wind path is formed in described interior partition, by arranging between adjacent two iron cores, there is partition in wind path, thus motor intensification can be reduced, and electric efficiency can be improved and improve rated power.
Description
Technical field
The utility model relates to a kind of rotor and motor.
Background technology
Along with the continuous increase of power of motor, and for the requirement reducing motor production cost in market and production process, the heat radiation of motor more and more becomes distinct issues.Traditional cast-aluminum rotor due to part wind path smooth, thus motor is occurred, and efficiency even temperature rise on the low side such as to be transfinited at the problem, limits the increase of high-voltage cast-aluminum rotor induction machine rated power.In order to solve the heat dissipation problem of high-power cast-aluminum rotor induction machine, existing solution increases the high and lengths of frame in the center of motor, or change non-ventilated motor into strong cool electric machine, but these changes can increase considerably the manufacturing cost of motor, raise product price, affect product competitiveness commercially.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of rotor and motor of new structure, make it have more value in industry.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide one can reduce motor intensification, and improves rotor and the motor of electric efficiency and raising rated power.
A kind of rotor of the present utility model, comprise some be arranged in order the iron core of setting, the some rotor bars be embedded in iron core, be arranged on described iron core two ends and connect adjacent rotor sliver end ring, be clamped in interior partition between two adjacent iron cores, be formed with wind path in described interior partition.
Further, described interior partition comprises and being oppositely arranged and the dividing plate be separately fixed on adjacent iron core and connect the collar of two dividing plates, and described wind path is formed by two dividing plates.
Further, the two ends of dividing plate described in be oppositely arranged two respectively indent are formed fluted, and the described collar is arranged in described groove.
Further, described groove has domatic, two domatic both sides supported respectively at the collar in each described interior partition.
Further, described rotor also comprises the rotor fan blade be arranged on outside end ring.
Further, the width of described iron core is 30mm, and often save iron core by 60 and 0.5mm thick silicon steel sheet accumulation form.
Further, described rotor is cast-aluminum rotor.
The utility model additionally provides a kind of motor, comprises stator and above-mentioned rotor.
By such scheme, the utility model at least has the following advantages: have partition in wind path by arranging between adjacent two iron cores, thus can reduce motor intensification, and can improve electric efficiency and improve rated power.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model rotor;
Fig. 2 be in Fig. 1 iron core and interior partition assemble after amplification view.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Motor described in the utility model one preferred embodiment comprises stators and rotators, and described stator is identical with stator structure of the prior art, therefore does not repeat at this.See Fig. 1 and Fig. 2, described rotor is cast-aluminum rotor, and it comprises and is somely arranged in order the iron core 1 of setting, the some rotor bars (not shown) be embedded in iron core 1, is arranged on described iron core 1 two ends and the end ring 2 connecting adjacent rotor sliver, the rotor fan blade 4 that is clamped in the interior partition 3 between two adjacent iron cores 1 and is arranged on outside end ring 2.The width of described iron core 1 be 30mm (number in the figure a), and often save iron core 1 by 60 and the thick silicon steel sheet accumulation of 0.5mm form.Wind path 31 is formed in described interior partition 3.
Described interior partition 3 comprises and being oppositely arranged and the dividing plate 32 be separately fixed on adjacent iron core 1 and connect the collar 33 of two dividing plates 32, and described wind path 31 is formed by two dividing plates 32.The two ends of dividing plate 32 described in be oppositely arranged two respectively indent form fluted 34, the described collar 33 is arranged in described groove 34, described groove 34 has bottom surface 35, domatic 36 and connection bottom surface 35 of vertical described bottom surface 35 setting and the hollows 37 of domatic 36, and two domatic 36 in each described interior partition 3 support respectively in the both sides of the collar 33.
The operation principle of above-mentioned cast-aluminum rotor is as follows: after cast-aluminum rotor adds interior partition 3, thus add the length of wind path 31, in addition, the relatively same rotor that interior partition 3 is not set, iron core 1 length of the present utility model increases, and to make itself and interior partition 3 together play the effect increasing the actual area of dissipation of rotor, thus reduces electric machine temperature rise, also improve electric efficiency simultaneously, the rated power of high-voltage cast-aluminum rotor induction machine is increased greatly.
In sum, above-mentioned rotor has partition 3 in wind path 31 by arranging between adjacent two iron cores 1, thus motor intensification can be reduced, and electric efficiency can be improved and improve rated power, thus be conducive to the market competitiveness improving high-power cast-aluminum rotor induction machine.
The above is only preferred implementation of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
