Description

Plastic-coated stator of plastic-coated motor

Technical Field

The utility model relates to a plastic-coated stator of a plastic-coated motor.

Background

At present, in traditional plastic envelope motor field, general plastic envelope stator core comprises two semicircle cores and four insulation framework, overlaps respectively in every semicircle core's the periphery and establishes two insulation framework that mould plastics, prevents wire winding and the iron core contact and the breakdown that leads to, and because traditional insulation framework needs artifical cover to go on the iron core, so can loosen a bit a little that generally does, so lead to the wire winding inslot area to diminish, the groove filling rate is generally on the low side, the motor efficiency is low. And the frame burr is many, when producing the wire winding, is very easily hindered the line. In addition, the production efficiency is low because workers manually sleeve the framework and assemble the two semicircular iron cores, and the production and manufacturing cost is correspondingly increased.

SUMMERY OF THE UTILITY MODEL

The plastic-packaged motor plastic-coated stator solves the problems in the prior art at least to a certain extent, and therefore the plastic-packaged motor plastic-coated stator which is reasonable in structure, low in design cost and convenient to popularize is provided, and the defects in the prior art are overcome.

The above purpose is realized by the following technical scheme:

the utility model provides a stator is moulded to plastic envelope motor package, includes stator core, the interior limit of iron core is equipped with a plurality of groove teeth that inwards extend respectively, adjacent two all form the wire winding groove between the groove tooth, stator core the periphery of groove tooth reaches the inner wall in wire winding groove all is equipped with the insulating layer.

In some embodiments, the stator core is a full round hollow structure.

In some embodiments, the insulating layer is integrally formed by injection molding.

In some embodiments, the insulation layer is provided with a plurality of protrusions on the outer side away from the stator core.

In some embodiments, the protrusions are disposed symmetrically up and down.

Compared with the prior art, the utility model at least comprises the following beneficial effects:

(1) the utility model solves the problems that in the actual production and use, the insulation layer is arranged to prevent the enameled wire from contacting with the iron core to cause breakdown and poor voltage resistance, and the insulation layer and the iron core are integrally formed by injection molding.

(2) The utility model cancels the process of manually sleeving the framework by workers and the process of assembling the two semicircular iron cores, improves the production efficiency, saves the production cost, has less burrs of the integrally formed plastic-coated stator and better wrapping property, can better avoid the problem of wire damage and wire breakage in the production and winding process, improves the production efficiency and reduces the production cost.

Detailed Description

The present invention is illustrated by the following examples, but the present invention is not limited to these examples. Modifications to the embodiments of the utility model or equivalent substitutions of parts of technical features without departing from the spirit of the utility model are intended to be covered by the scope of the claims of the utility model.

As shown in fig. 1-3, a plastic-coated stator of a plastic-packaged motor comprises a stator core 2, wherein the stator core 2 is of a full-circle hollow structure. The interior limit of iron core 2 is equipped with a plurality of inside extension's slot tooth 21 respectively, adjacent two all form wire winding groove 22 between the slot tooth 21, stator core 2 the periphery of slot tooth 21 reaches wire winding groove 22's inner wall all is equipped with insulating layer 1. The insulating layer 1 is integrally formed by injection molding.

Through setting up insulating layer 1, prevent that the enameled wire from with stator core 2 contact causes puncture, withstand voltage bad. Through with insulating layer 1 with stator core 2 an organic whole is moulded plastics and is formed, compares with traditional technology, has increased the inslot area, can accomplish higher groove fullness rate to make motor efficiency higher. And the process of manually sleeving the framework by workers and the process of assembling the two semicircular iron cores are cancelled, so that the production efficiency is improved, and the production cost is saved. Practice proves that the integrally formed plastic-coated stator has fewer burrs and better wrapping performance, the problem of wire damage and wire breakage in the production and winding process can be better solved, the production efficiency is improved, and the production cost is reduced.

Further, insulating layer 1 is kept away from the outside of stator core 2 is equipped with a plurality of archs 11, arch 11 sets up for longitudinal symmetry, arch 11 can be fixed a position when stator module moulds plastics, prevents that stator module from shifting.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the utility model.
