Abstract
The invention relates to an armature core structure of a DC (Direct Current) motor. The armature core structure comprises an armature iron core and a shaft, wherein the armature iron core is arranged at the periphery of the shaft and comprises a first armature punching plate and second armature punching plates, the second armature punching plates are arranged at two ends of the first armature punching plate, the first armature punching plate and the second armature punching plates are respectively provided with a groove for the embedment of an armature coil, and the cross section of each section armature punching plate is larger than that of the first armature punching plate. The armature core structure disclosed by the invention has the advantages that the structure is compact, under the condition of ensuring the qualified magnetic performance characteristic of an electric motor and due to the adoption the combining and stacking of the armature punching plates in different groove types, the wire inserting of the armature coils can be convenient, and the armature coil can be prevented from being damaged through the arrangement of slot insulations.
Description
Technical field
The present invention relates to direct current machine, relate in particular to a kind of armature core structure of direct current machine.
Background technology
In the prior art; Conventional dc motor armature iron core adopts the armature stamping with same grooved to laminate formation; In the groove of armature stamping, armature coil is installed, it is longer that the bending part at armature coil straight line place exceeds armature core, can be placed directly in the groove of armature stamping; But compact for the space, the direct current machine that end space is limited, it is partly very little that iron core is stretched out in the bending place of armature coil; Corner increases, if be placed directly in the groove the inside of armature stamping, coil rule difficulty; The end ventilation effect is also bad, and causes the armature coil damage easily.
Summary of the invention
The applicant provides another kind of simple in structure to above-mentioned shortcoming, and the armature core structure of direct current machine easy for installation has the armature coil rule conveniently, improves the advantage of motor quality.
The technical scheme that the present invention adopted is following:
A kind of armature core structure of direct current machine comprises armature core and axle, and armature core is installed on the periphery of axle, and armature core comprises first armature stamping and second armature stamping, and second armature stamping is installed on the two ends of first armature stamping; On first armature stamping and second armature stamping, have the chimeric groove of pivot coil of can supplying power, the cross section of the second armature stamping groove is greater than the cross section of the first armature stamping groove.
Its further technical scheme is:
The groove width of said second armature stamping (2) is wider than the first armature stamping 2.2mm-2.3mm, and the groove height is higher than the first armature stamping 1.2mm-1.3mm.
Beneficial effect of the present invention is following:
Compact conformation of the present invention; Guaranteeing under the qualified condition of motor magnetic property characteristic, laminating, not only making things convenient for the armature coil rule through adopting two kinds of different armature stamping combinations of grooved; And through being provided with the notch insulation; Effectively the protection armature coil does not damage, and guarantees that motor normally uses, and has improved the quality and the life-span of motor.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described.
Like Fig. 1, shown in Figure 2; The present invention includes armature core and axle 5; Armature core is installed on the periphery of axle 5, and armature core comprises first armature stamping 1 and second armature stamping 2, like Fig. 2, shown in Figure 3; On first armature stamping 1 and second armature stamping 2, have the first open slot 1-1 and the second open slot 2-1, the cross section of the said second open slot 2-1 is greater than the cross section of the first open slot 1-1.Like Fig. 6, shown in Figure 7, interlocking armature coil 7 in the groove; Second armature stamping 2 is installed on the two ends of first armature stamping 1; One side of two second armature stampings 2 is installed rotor ventilation frid 3; The effect of rotor ventilation frid 3 is to make wind uniformly through the effect on armature core surface, and an end that is positioned at ventilation channel plate 3 is also installed trim ring 4.The groove width of the second open slot 2-1 is wider than the first open slot 2.2mm-2.3mm, and the groove height is higher than the first open slot 1.2mm-1.3mm.Like Fig. 2, shown in Figure 7, for preventing to be subjected to displacement between armature coil 7 and the armature core, notch insulation 6 is installed, notch insulation 6 is installed among the open slot 2-1 of second armature stamping 2, and the end of protection armature coil is injury-free.The structure of notch insulation 6 is as shown in Figure 4, and notch insulation 6 adopts 1NHN composite insulating foil material to process.
Compact conformation of the present invention; Guaranteeing under the qualified condition of motor magnetic property characteristic, laminating, not only making things convenient for the armature coil rule through adopting two kinds of different armature stamping combinations of grooved; And through being provided with the notch insulation; Effectively the protection armature coil does not damage, and guarantees that motor normally uses, and has improved the quality and the life-span of motor.
More than describing is to explanation of the present invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of basic structure of the present invention, the present invention can do any type of modification.
