Abstract
The utility model discloses a kind of minisize dc magneto life structure, comprise stator, rotor, brush, rotating shaft, armature core, armature winding, commutator, pcb board and patch capacitor; Described armature winding is fixed in rotating shaft; Described commutator and armature winding lay out to hold and are connected; Described brush is arranged on commutator upper end; Described stator is for maintaining static and being arranged on overall outer end; Described rotor is fixedly connected with rotating shaft one end; Described armature core is arranged in the middle of armature winding; Patch capacitor is provided with three of series connection altogether on pcb board, and three patch capacitors are also connected with three poles of commutator; This minisize dc magneto life structure, functionally says, the loop structure that pcb board and patch capacitor and commutator are formed comparatively piezo-resistance electric capacity is comparatively large, and then the effect absorbing motor high-frequency spark is better.
Description
Technical field
The utility model relates to direct current permanent magnet motor applied technical field, especially a kind of minisize dc magneto life structure.
Background technology
Brushless, permanently excited direct current motor is the DC motor being set up magnetic field by one or more permanent magnet, and its performance is similar to the DC motor with separate excitation of constant excitation megnet electric current, can carry out speed governing easily by change armature voltage.Compared with separated exciting DC motor, having the advantages such as volume is little, efficiency is high, structure is simple, copper consumption is few, is the main feature of low powered DC motor; But all employing of like product adds varistor and solves steering gear and frequently commutate and the spark that produces and then the effect reaching life-saving more in the market; But because piezo-resistance inherently has less electric capacity, and then when the engine commutator being commutates, spark absorbs not exclusively, causes life-time dilatation to be limited in scope, cannot reach the requirement in life field.
Prior art can not meet the needs of people, and for making up prior art deficiency, the utility model aims to provide a kind of minisize dc magneto life structure.
For achieving the above object, the utility model by the following technical solutions: a kind of minisize dc magneto life structure, comprises stator, rotor, brush, rotating shaft, armature core, armature winding, commutator, pcb board and patch capacitor; Described armature winding is fixed in rotating shaft; Described commutator and armature winding lay out to hold and are connected; Described brush is arranged on commutator upper end; Described stator is for maintaining static and being arranged on overall outer end; Described rotor is fixedly connected with rotating shaft one end; Described armature core is arranged in the middle of armature winding; Described patch capacitor is fixed by welding on pcb board.
Further, described patch capacitor is provided with three of series connection altogether on pcb board, and three patch capacitors are also connected with three poles of commutator.
Compared with prior art, the beneficial effects of the utility model are: this minisize dc magneto life structure, functionally say, the loop structure that pcb board and patch capacitor and commutator are formed comparatively piezo-resistance electric capacity is comparatively large, and then the effect absorbing motor high-frequency spark is better;
Structurally, electric capacity is rationally placed on pcb board, pcb board leaves three pads between electric capacity simultaneously, be convenient to realize automatic welding.

Accompanying drawing explanation
Fig. 1 is the overall cross-sectional view of the utility model;
Fig. 2 is the structural representation of patch capacitor of the present utility model on pcb board;
Wherein: 1, stator, 2, rotor, 3, brush, 4, rotating shaft, 5, armature core, 6, armature winding, 7, commutator, 71, pcb board, 72, patch capacitor.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, a kind of minisize dc magneto life structure, comprises stator 1, rotor 2, brush 3, rotating shaft 4, armature core 5, armature winding 6, commutator 7, pcb board 71 and patch capacitor 72; Described armature winding 6 is fixed in rotating shaft 4; Described commutator 7 and armature winding go out to hold around 6 and are connected; Described brush 3 is arranged on commutator 7 upper end; Described stator 1 is for maintaining static and being arranged on overall outer end; Described rotor 2 is fixedly connected with rotating shaft 4 one end; Described armature core 5 is arranged in the middle of armature winding 6; Described patch capacitor 72 is fixed by welding on pcb board 71.
Further, described patch capacitor 72 is provided with three of series connection altogether on pcb board 71, and three patch capacitors 72 are also connected with three poles of commutator 7.
The utility model realizes the life-time dilatation principle of work and power: three patch capacitor series weldings are connected on pcb board, and three that are welded on commutator between three patch capacitors respectively are extremely gone up; When commutator and brush are when commutating, patch capacitor absorbs the high-frequency spark that motor produces when commutating; When this part energy of capacitive absorption is when discharging, is sponged by pcb board again, between patch capacitor and pcb board, forming a loop.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection range that all should be included in technical solutions of the utility model.
