Abstract
The utility model relates to an armature with an improved structure. The armature comprises an armature core and an armature winding, wherein the armature core is formed by laminating a plurality of armature laminations; the circumferences of the armature laminations are provided a plurality of grooves inwards for the armature winding to be wound; and at least one side of each groove is provided with a second groove along the circumferential direction. According to the armature with the improved structure, through respectively arranging the second grooves at both sides or single side of the grooves of the armature laminations, a long and narrow channel is formed on the armature core, and thus, insulated paint can enter through the long and narrow channel to form a paint film on the surface of the armature winding, thereby, a preset effect is achieved.
Description
(1) technical field
The utility model relates to a kind of armature.
(2) background technology
Armature is made up of armature core and armature winding, and armature core is built up by silicon steel sheet plurality of thin, the cylindrical trough of belt, and as shown in Figure 1, the lamination of armature core can reduce eddy current.Armature winding is installed in the groove at lamination external diameter edge, and the winding wire turn is received copper segment respectively, and armature is installed on the armature shaft.In the prior art, armature need carry out varnished insulation to be handled, and insulating varnish mainly plays two effects greatly: the first, and fixation.Live coil stationary, the vibrations that not so do not stop after the energising can cause energy loss, and noise is also very big, causes the rotor life-span low, and the second, certain insulating effect, the outermost impregnating varnish of coil can be described as a kind of of insulation replenished.But armature core is after the armature winding coiling, and insulating varnish can't get into inner through the groove of armature core, and then the partial interior enamelled wire can't form paint film.
(3) summary of the invention
In order to overcome in the prior art insulating varnish unapproachable technical problem in part position in the armature core, the utility model provides a kind of armature that can make armature winding can fully contact the architecture advances of insulating varnish.
The technical scheme that the utility model solves its technical problem is:
A kind of armature of architecture advances; Comprise armature core and armature winding; Described armature core is built up by some armature punchings, inwardly offers the groove that some power supply pivot windings twine on the circumference of described armature punching, and at least one side of described groove offers second groove along circumferential direction.
As improvement, the both sides of groove all are provided with second groove.
As improvement, the length of second groove is less than the length of groove, and the degree of depth of second groove is 1/5～1/20 of a recess width.
Groove both sides at the armature punching that builds up armature core are offered second groove again; After then armature punching builds up; Form a little gallery in a longitudinal direction; When armature was handled at dipping lacquer, armature core is inner to form paint film on the armature winding surface thereby paint is through getting in this gallery, thereby reaches preset effect.The effect that second groove is all offered in the both sides of groove is preferable, and insulating varnish can get into from both sides.
The beneficial effect of the utility model is: the utility model is through both sides or one-sided second groove of offering at the groove of armature punching; Make armature core form a gallery; Then insulating varnish can get into through this gallery, forms paint film on the armature winding surface, reaches preset effect.
(4) description of drawings
Fig. 1 is the prior art constructions sketch map.
Fig. 2 is the part-structure sketch map of the utility model.
(5) embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
A kind of armature of architecture advances comprises armature core and armature winding, and armature core is built up by some armature punchings 1; Inwardly offer the groove 2 that some power supply pivot windings twine on the circumference of armature punching 1, as shown in Figure 1, be the structure of the armature punching 1 of prior art; As shown in Figure 2; Be the structural representation of the utility model, the utility model offers second groove 3 at least one side of groove along circumferential direction, promptly is provided with second groove 3 in the one or both sides of groove.The length of second groove 3 is less than the length of groove 2, and the degree of depth of second groove is 1/5～1/20 of a recess width.
Offer second groove 3 again in the groove both sides of the armature punching that builds up armature core 1; After then armature punching builds up; Form a little gallery in a longitudinal direction, when armature was handled at dipping lacquer, paint was inner through getting into armature core in this gallery; Then the armature winding surface energy fully contacts insulating varnish and forms paint film, thereby reaches preset effect.The effect that second groove is all offered in the both sides of groove is preferable, and insulating varnish can get into from both sides.
Claims (3)
1. the armature of an architecture advances; Comprise armature core and armature winding; Described armature core is built up by some armature punchings; Inwardly offer the groove that some power supply pivot windings twine on the circumference of described armature punching, it is characterized in that: at least one side of described groove offers second groove along circumferential direction.
2. the armature of a kind of architecture advances according to claim 1, it is characterized in that: the both sides of described groove all are provided with second groove.
3. the armature of a kind of architecture advances according to claim 1 and 2, it is characterized in that: the length of described second groove is less than the length of groove, and the degree of depth of second groove is 1/5～1/20 of a recess width.
