Abstract
The utility model relates to the technical field of rotor structures, and particularly relates to a DC brushless rotor structure comprising multiple magnetic tiles, a first iron core and a second iron core. A magnetic tile external ring is formed by the multiple magnetic tiles. The rotor structure is composed of, from inside to outside in turn, the second iron core, the first iron core and the magnetic tiles. All the magnetic tiles are connected and positioned via injection molding of a first plastic layer. The first iron core and the second iron core are separated by adopting a second plastic layer. Rotor reliability can be enhanced, original handwork bonding manufacturing technology can be optimized, induction voltage on a motor rotating shaft can be reduced, shaft current can be reduced, bearing electrostatic corrosion can be effectively prevented and the service life of a motor bearing can be enhanced.
Description
Technical field
The utility model relates to rotor structure technical field, especially a kind of brush DC rotor structure.
Background technology
Existing direct current machine industry rotor generally all adopts manually adhered magnetic shoe technique and rotating shaft directly to contact with magnetic guiding loop iron core.Manually adhered magnetic shoe exists the rear magnetic shoe of risk, inefficacy of bonding glue inefficacy to come off and more complicated is compared in manual operation.Rotating shaft directly contacts with magnetic guiding loop iron core, causes in rotating shaft because electrostatic induction causes potential rise.
Utility model content
In order to overcome the deficiency of existing technology, the utility model provides a kind of brush DC rotor structure.
The utility model solves the technical scheme that its technical problem adopts: a kind of brush DC rotor structure, comprise some magnetic shoes, iron core one, iron core two, this rotor structure is followed successively by iron core two, iron core one, magnetic shoe from inside to outside, some magnetic shoes along iron core one cylindrical circlewise, all magnetic shoes are placed on diameter two ends and have different polarity on diameter section, and the injection moulding by plastic layer one between described each magnetic shoe realizes connection location.This programme can improve the reliability of rotor, has stopped the possibility that long rear glue of time lost efficacy.
According to another embodiment of the present utility model, further comprise, between described iron core one and iron core two, adopt plastic layer two isolation.This programme can reduce the induced voltage on machine shaft.
The beneficial effects of the utility model are that the utility model can improve the reliability of rotor, optimizes the bonding manufacturing process of former craft, reduces induced voltage on machine shaft, reduces shaft current, effectively prevents the corrosion of bearing static, the useful life of improving motor bearings.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cutaway view of the present utility model;
In figure 1, magnetic shoe, 2, iron core one, 3, iron core two, 4, plastic layer one, 5, plastic layer two.
Embodiment
As shown in Figure 1, 2, a kind of brush DC rotor structure, comprise some magnetic shoes 1, iron core 1, iron core 23, this rotor structure is followed successively by iron core 23, iron core 1, magnetic shoe 1 from inside to outside, some magnetic shoes 1 along iron core one 2 cylindrical circlewise, all magnetic shoes 1 are placed on diameter two ends and have different polarity on diameter section, and the injection moulding by plastic layer 1 between each magnetic shoe 1 realizes connection location.Between iron core 1 and iron core 23, adopt plastic layer 25 isolation.
The utility model rotor reliability improves, and optimizes the bonding manufacturing process of former craft, reduces induced voltage on machine shaft, reduces shaft current.Effectively prevent the corrosion of bearing static, the useful life of improving motor bearings.
