Abstract
The utility model relates to a direct current motor component, in particular to a direct current motor commutator, comprising a commutator body which is composed of a commutating segment and a mica plate; a plurality of spiral slots positioned on the outer surface circle of the commutator. By arranging the spiral slots on the outer surface circle of the commutator, the utility model has the advantages of discharging the carbon powder along the spiral slots caused by the motor while in use, without storage in the insulation mica groove among the segments, and enabling that the heat on the surface of the brush and the commutator get lost easily and small brush wear; improving the motor commutation, decreasing the possibility greatly that the commutator is out of work, thereby the reliable work of the motor can be ensured.
Description
Technical field
The utility model relates to the DC motor parts, is specially the DC motor commutator.
Background technology
The structure of existing DC motor commutator is between each commutator segment micarex to be arranged; After whole armature has assembled, the finish turning commutator face, following quarter the commutator-segment insulation mica.Be commutator segment and mica slot on the commutator working face, commutator contacts the generation heat at work and is difficult for shedding with brush, the easy carbon distribution powder of commutator working face, thus produce faults such as spark, ring fire.
Summary of the invention
The utility model solves the problem of the existing easy carbon distribution powder of DC motor commutator working face, and a kind of DC motor commutator that improves structure that has is provided.
The utility model is to adopt following technical scheme to realize: the DC motor commutator comprises the commutator body that is made of commutator segment and micarex, at the commutator face circumference helix groove of having got on the bus.
The utility model is by setting up helix groove at the commutator face circumference, the carbon dust powder that produces in the time of can making the motor operation is discharged along helicla flute, and do not stockpile in the lamination insulation mica slot, and brush and commutator working face are dispelled the heat easily, make the brush abrasion little; Improve motor commutation, greatly reduce the probability that commutator goes wrong, effectively guaranteed the motor reliability of operation.
Description of drawings
Fig. 1 is the structural representation of DC motor commutator described in the utility model;
Embodiment
The DC motor commutator comprises the commutator body 1 that is made of commutator segment and micarex, has helix groove 2 on the commutator face circumference.
Helix groove groove depth 1.2mm, helix groove are spaced apart 3/inch.
Claims (2)
