Abstract
The utility model discloses a cast-aluminum rotor for a precision motor, which comprises an iron core. The iron core is provided with a bearing hole. The two ends of the iron core are provided with a first aluminum ring and a second aluminum ring. The second aluminum ring is circumferentially provided with at least two balancing columns. The two ends of the iron core are also provided with permeable sheets. The iron core is provided with at least two ventilation holes and at least three self-riveting rivets. The cast-aluminum rotor has the advantages of compact structure and good heat dissipation effect. When the cast-aluminum rotor is applied to the precision motor, the efficiency of the motor is effectively improved. Meanwhile, the energy consumption is lowered.
Description
Technical field
The utility model relates to a kind of precision electric motor cast-aluminum rotor, belongs to the accessory of motor.
Background technology
Rotor is one of important accessory of forming by motor, and used rotor has wound rotor, p-m rotor, cast-aluminum rotor etc. several usually at present, and wherein cast-aluminum rotor is generally used in the precision electric motor.Existing cast-aluminum rotor exists usually that efficient is low, energy consumption is high, structure problem such as compactness inadequately.
The utility model content
The utility model is at the deficiencies in the prior art, and purpose is to provide a kind of precision electric motor cast-aluminum rotor, makes its compact conformation, can improve efficiency of motor.
The utility model realizes that the technical scheme of above-mentioned purpose is: the precision electric motor cast-aluminum rotor, comprise iron core, and iron core is provided with dead eye, is provided with the first aluminium ring and the second aluminium ring at the iron core two ends, also along the circumferential direction is provided with at least 2 balance columns on the second aluminium ring.
As the further setting of such scheme, described iron core two ends also are provided with empty sheet.
As the further setting of such scheme, described iron core is provided with at least 2 ventilation holes.
As the further setting of such scheme, described iron core is provided with at least 3 from the riveting rivet.
The beneficial effects of the utility model are: the utility model compact conformation, thermal diffusivity is good, can effectively improve efficiency of motor after being applied in the motor, cuts down the consumption of energy.
Description of drawings
Fig. 1 is half sectional view of the present utility model;
Fig. 2 is the right view of Fig. 1.
Among the figure: balance columns 1, from riveting rivet 2, ventilation hole 3, the first aluminium ring 4, the second aluminium ring 5, dead eye 6, iron core 7, saturating empty sheet 8.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1 and Figure 2, the precision electric motor cast-aluminum rotor comprises iron core 7, and iron core 7 is provided with dead eye 6, is provided with the first aluminium ring 4 and the second aluminium ring 5 at iron core 7 two ends, also along the circumferential direction is provided with at least 2 balance columns 1 on the second aluminium ring 5; Described iron core 7 two ends also are provided with empty sheet 8; Described iron core 7 is provided with at least 2 ventilation holes 3; Described iron core 7 is provided with at least 3 from riveting rivet 2.The design of ventilation hole 3 and saturating empty sheet 8 is more conducive to heat radiation, can improve efficiency of motor, from the design of riveting rivet 2 punching can not riveted together by cramp, makes the structure of rotor compacter.
