Description

Concentrated winding motor insulation framework

Technical Field

The utility model relates to a concentrate winding motor insulation skeleton, concretely relates to concentrate winding motor insulation skeleton's improvement belongs to motor technical field.

Background

In the production process of the concentrated winding motor, the insulation of the motor enameled wire and the stator core is mostly realized by the matching of an insulating framework and slot bottom insulating paper, and the slot bottom insulating paper is generally made of a thin material of 0.2-0.3mm, so that the effective area of the stator slot is increased as much as possible, and the production requirements of a high-slot-fullness-rate and high-efficiency motor are met. However, in the process of winding the coil, due to reasons such as poor insulation paper forming at the bottom of the slot or interference between a winding needle and the insulation paper, the phenomenon that the enameled wire is wound between the iron core and the insulation paper at the bottom of the slot is easy to occur, so that the insulation protection purpose of the insulation paper cannot be achieved, the motor is scrapped, the phenomenon is not easy to find through appearance detection, a product flows to a client, the complete machine is easily scrapped due to poor insulation in complete machine load operation, and even hidden danger is caused to the life safety of a user.

Disclosure of Invention

To the above-mentioned defect that exists among the prior art, the utility model provides a can prevent that the enameled wire from being drawn into the concentrated winding motor insulation skeleton between iron core and the insulating paper at the bottom of the groove.

The utility model discloses a realize through following technical scheme: the utility model provides a concentrated winding motor insulation skeleton, includes insulation skeleton main part, characterized by: the two ends of the winding port end framework of each winding part of the insulation framework main body are respectively provided with a convex body, and one end, facing the mounting position of the insulation paper in the stator slot, of each convex body is provided with an insulation paper clamping slot matched with the insulation paper.

The utility model discloses in, set up the insulated paper draw-in groove through setting up the convex body and at the convex body towards the one end of stator inslot insulated paper mounted position, can fix the insulated paper of stator inslot through the insulated paper draw-in groove. Even there is the bad problem of shaping in insulating paper, still can effectively fix insulating paper through the insulating paper draw-in groove, the condition that the enameled wire was drawn into between iron core and the insulating paper at the bottom of the groove during can effectively prevent the wire winding.

Furthermore, the insulation paper clamping groove is of a U-shaped groove structure, and the bottom surface of the groove is a positioning surface of the upper end edge of the insulation paper. The bottom surface of the groove in the U-shaped groove can be used for positioning the upper end edge of the insulation paper, so that the insulation paper is prevented from moving in the winding process, and the insulation effect between the insulation paper and the stator core is ensured.

Furthermore, the insulation paper clamping groove is formed by a protruding part on the convex body and a winding port end framework of the winding part of the insulation framework main body.

Furthermore, in order to facilitate processing and manufacturing, the convex body and the insulating framework main body are integrally formed.

Furthermore, in order to ensure smooth winding, the edges and corners of the convex body are in smooth transition.

The utility model has the advantages that: the utility model discloses a both ends at the wire winding mouth end skeleton of every wire winding portion of insulating frame main part set up a convex body respectively and set up the insulated paper draw-in groove at the convex body towards the one end of stator slot internal insulation paper mounted position, can effectively fix the insulated paper of stator slot through the insulated paper draw-in groove, and the enameled wire is drawn into the condition between iron core and the insulated paper at the bottom of the groove when can effectively preventing the wire winding, has improved the shaping quality of winding greatly, has improved the quality of product.

fig. 3 is a partially enlarged schematic view of the winding portion of fig. 2;

in the figure, 1, an insulating framework main body, 11, a winding part, 111, a winding port end framework, 12, a winding port, 13, a stator slot, 2, a convex body, 21, a protruding part, 3 and an insulating paper clamping slot.

Detailed Description

The invention will now be further described by way of non-limiting examples with reference to the accompanying drawings:

as shown in the attached drawings, the insulating framework of the concentrated winding motor comprises an insulating framework main body 1, the insulating framework main body 1 is the insulating framework of the concentrated winding motor in the prior art, the insulating framework main body 1 is provided with a plurality of winding parts 11 and stator slots 13, and winding openings 12 are formed between the adjacent winding parts 11. The method is characterized in that: the two ends of the winding port end framework 111 of each winding part 11 of the insulation framework main body 1 are respectively provided with a convex body 2, and one end of each convex body 2 facing the installation position of the insulation paper in the stator slot is provided with an insulation paper clamping slot 3 capable of being matched with the insulation paper. The slot width of the insulation paper slot 3 should match the thickness of the insulation paper.

Preferably, the insulation paper slot 3 is a U-shaped slot structure, and the bottom surface of the slot is a positioning surface of the upper end edge of the insulation paper. The bottom surface of the groove in the U-shaped groove can be used for positioning the upper end edge of the insulation paper, so that the insulation paper is prevented from moving in the winding process, and the insulation effect between the insulation paper and the stator core is ensured.

In order to simplify the structure, it is more preferable that the insulation paper slot 3 is formed by a protrusion 21 on the convex body 2 and the bobbin 111 at the winding end of the winding part 11 of the insulation bobbin main body 1.

For convenience of processing and manufacturing, the convex body 2 is preferably integrally formed with the insulating framework main body 1.

In order to ensure smooth winding, the edges of the convex bodies 2 are in smooth transition.

The utility model discloses during the use, the upper end limit of the good insulating paper of cartridge inserts the utility model provides an in the insulating paper draw-in groove and fixed, the tank bottom surface of insulating paper draw-in groove is fixed a position through the upper end limit of insulating paper. Because the insulating paper is fixed by the insulating paper draw-in groove, the condition that the enameled wire is rolled between the insulating paper at the groove bottom and the iron core can not occur when the enameled wire is wound, and the problem that a winding needle interferes with the insulating paper can not occur. Even the bad problem of insulating paper shaping appears, still can effectively fix insulating paper through the insulating paper draw-in groove, the condition between enameled wire is drawn into iron core and the insulating paper at the bottom of the groove when can effectively prevent the wire winding.

Other parts in this embodiment are the prior art, and are not described herein again.
