Abstract
The utility model relates to an electric motor rotor and motor. This electric motor rotor, it includes rotor core, the iron core inslot of rotor core excircle is equipped with the busbar, is equipped with the rotor clamping ring at rotor core's both ends, still includes the rotor ring that keeps out the wind, is equipped with the rotor ring that keeps out the wind along the interior circle department that the busbar of motor air inlet end stretches out the rotor core part, the material that the rotor kept out the wind the ring is insulating material. The utility model discloses because internal surface at the busbar has set up the insulating rotor ring that keeps out the wind to when the motor operateed, the cooling air was acted on by rotor clamping ring centrifugal force, will blow to keep out the wind ring back at the rotor and kept off, compelledly entered into rotor yoke portion, thereby had realized the cooling of antitrochanter yoke portion, greatly reduced the temperature rise of rotor, ensured the operation of motor safe and reliable. The utility model discloses still relate to a motor that contains this kind of electric motor rotor.
Description
Technical field
The utility model relates to field of motor manufacturing, particularly relates to a kind of rotor and motor.
Background technology
At present, for reducing the temperature rise of motor, the general ventilation and heat all considering stator winding, for rotor temperature rise not damage stator winding or miscellaneous part for basis for estimation, busbar is provided with in the iron core slot of rotor core cylindrical, under the effect of centrifugal rotor trim ring, cooling air is easily discharged on rotor air gap and stator core by the gap of busbar between core ends, thus rotor core yoke portion cooling air reduces, rotor temperature rise is high, when rotor temperature rise is too high, not only can cause rotor end ring and the weldering of busbar pine, bearing can be transferred heat to rapidly simultaneously, adverse effect is brought to bearing.
Utility model content
The purpose of this utility model is to overcome above defect, provides a kind of rotor and the motor that reduce rotor temperature rise.
The technical solution of the utility model is: a kind of rotor, it comprises rotor core, busbar is provided with in the iron core slot of rotor core cylindrical, rotor pressing ring is provided with at the both ends of rotor core, also comprise rotor air baffle ring, the inner circle that busbar along motor air intake stretches out rotor core part is provided with rotor air baffle ring, and the material of described rotor air baffle ring is isolation material.
Preferably, described rotor air baffle ring is bonded on busbar.
The utility model also relates to a kind of motor, and it comprises rotor, and described rotor is rotor described above.
Advantageous Effects of the present utility model is, owing to being provided with the rotor air baffle ring of insulation at the inner surface of busbar, thus when motor rotation, cooling air is by rotor pressing ring centrifugal action, wind is returned by gear after rotor air baffle ring, is forced into rotor yoke, thus achieves the cooling to rotor yoke, greatly reduce the temperature rise of rotor, ensure that motor safety reliability service.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is that rotor air baffle ring place cooling air is to schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to accompanying drawing, a kind of rotor, it comprises rotor core 1, busbar 2 is provided with in the iron core slot of rotor core 1 cylindrical, rotor pressing ring 3 is provided with at the both ends of rotor core 1, also comprise rotor air baffle ring 4, the inner circle that busbar 2 along motor air intake stretches out rotor core 1 part is provided with rotor air baffle ring 4, the material of described rotor air baffle ring 4 is isolation material, described rotor air baffle ring 4 is bonded on busbar 2, when motor rotates, the cooling air that rotor air baffle ring 4 prevents rotor pressing ring 3 from discharging leaks from busbar 2 end crevice, forcing functions wind passes through from the ventilation hole of rotor core 1, thus make cooling air reduce the temperature rise of rotor core 1 and rotating shaft.
The utility model also relates to a kind of motor, and it comprises rotor, and described rotor is rotor described above.
Claims (3)
