Description

A kind of motor stator

Technical field

The utility model relates to a kind of motor stator more particularly to a kind of stator of electrical motor of sewing machine.

Background technique

Several small slots are provided on the motor stator of industrial sewing machines at present, are then had mercy on enameled wire in slot phase On adjacent slot column, but the volume of this way slot and slot column is too small, and coiling can only make on some powerful motors With copper enameled wire, therefore cause the problem that motor quality is overweight, cost is excessively high, low efficiency and thermal diffusivity are bad.

Therefore it is badly in need of wanting a kind of motor stator to solve the above problems.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of motor stators, solve existing motor stator quality Heavy, at high cost, low efficiency and the bad problem of thermal diffusivity.

The utility model is described fixed to solve above-mentioned technical problem and the technical solution adopted is that provide a kind of motor stator Including stator body, the stator body diameter is 76 ± 5mm, opens that there are six the identical dovetail grooves of size on the stator body Hole, the trapezoidal slot upper end are arc side, are the identical solid post of six sizes, the width of the solid post between the trapezoidal slot Degree is 38 ± 3mm.The stator body center is equipped with center hole, and the trapezoidal slot lower end center is equipped with groove, described recessed Slot is connected to the center hole, and the center hole is equipped with rotor core.

Preferably, the distance L1 of the arc side to the stator body outer end is 6 ± 1mm, the straight line at the arc side both ends Distance L2 is 23 ± 2mm, and the trapezoidal slot lower end both ends distance L3 is 12 ± 2mm, the trapezoidal slot lower end center to institute Stating the paracentral distance of arc is 13 ± 2mm.

Preferably, the stator body is equipped with plastic housing, and there are six base angle, the plastic housing base angle coverings for the plastic housing The solid post is uniformly wound with aluminium enamel-covered wire on six footing of the plastic housing.

The utility model comparison prior art has following the utility model has the advantages that motor electronic provided by the utility model, passes through Provided with 6 slots and solid post, it can be full of aluminium enamel-covered wire, reached motor stator light weight, manufacturing cost is low, high-efficient And the effect that thermal diffusivity is good.

Specific embodiment

The utility model will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the motor stator structure schematic diagram of the utility model embodiment；Fig. 2 is the motor of the utility model embodiment Stator floor map figure.

Referring to Figure 1 and Fig. 2, the utility model is to solve above-mentioned technical problem and the technical solution adopted is that provide one kind Motor stator, stator body diameter are 76 ± 5mm, open that there are six the identical trapezoidal slot of size, trapezoidal slots on stator body Upper end is arc side, is the identical solid post of six sizes between trapezoidal slot, and the width of solid post is 38 ± 3mm.In stator body The heart is equipped with center hole, and trapezoidal slot lower end center is equipped with groove, and groove is connected to the center hole, and center hole, which is equipped with, to be turned Sub- iron core.

The distance L1 of arc side to stator body outer end is 6 ± 1mm, and the linear distance L2 at arc side both ends is 23 ± 2mm, trapezoidal Slot lower end both ends distance L3 is 12 ± 2mm, and trapezoidal slot lower end center to the paracentral distance of the arc is 13 ± 2mm.Six Aluminium enamel-covered wire is uniformly wound in a solid post, solid post both sides aluminium enamel-covered wire thickness is no more than slot.

Stator body is equipped with plastic housing, and there are six base angle, plastic housing base angles to cover solid post, six bottoms of plastic housing for plastic housing Aluminium enamel-covered wire is uniformly wound on foot.The stator can be used for 300W to the motor between 1100W.

In conclusion the utility model has reached motor stator light weight, manufacturing cost is low, high-efficient and thermal diffusivity is good Effect.

Although the utility model is disclosed as above with preferred embodiment, so it is not intended to limit the utility model, any Those skilled in the art, without departing from the spirit and scope of the utility model, when can make a little modification and it is perfect, therefore this The protection scope of utility model, which is worked as, to be subjected to the definition of the claims.
