Description

  The present invention relates to a motor bobbin, and more specifically, for example, a motor stator that constitutes a motor generator of a hybrid car, an electric vehicle or the like, and a motor that is externally fitted to a core material such as a magnetic core coil with windings wound. Related to bobbins.

  A hybrid vehicle or an electric vehicle is equipped with a motor generator that selectively functions as an electric motor and a generator. Such a motor generator is, for example, a motor stator having a cylindrical rotor fixed to an output shaft that is rotatably supported around an axis, and an inner peripheral surface that is separated from the outer peripheral surface of the rotor by a predetermined gap. And a motor housing that houses the motor stator. The motor generator generates heat by an operation such as acceleration or deceleration of the automobile and becomes a high temperature of 100 ° C. or higher. Therefore, it is necessary to sufficiently cool the motor generator in order to maintain a predetermined performance.

  Therefore, in order to effectively cool the motor generator, cooling oil is supplied into the motor housing, the motor stator and the rotor are immersed in the cooling oil, and cooling is performed by circulating the cooling oil. Yes.

By the way, the motor stator constituting such a motor generator is generally composed of a core material and a winding, and in order to insulate between the core material and the winding,
A winding is wound around a bobbin for a motor, and the bobbin around which the winding is wound is externally fitted to a core material.

  Conventionally, as such a motor bobbin, patent applications such as the following Patent Document 1 and Patent Document 2 have been made, and such a conventional motor bobbin is generally made of a synthetic resin, For example, in the case of a concentrated winding stator, polyphenylene sulfide or the like is used.

However, when the bobbin is made of such a synthetic resin, there is a problem that the thickness of the bobbin cannot be made thinner than a predetermined thickness. Incidentally, when bobbins are composed of the polyphenylene sulfide, the limit is about 0.6 mm. The thickness of the bobbin also affects specific physical properties required for the bobbin such as the line area ratio and heat dissipation, and there is a demand for making the bobbin as thin as possible.

JP 2005-102454 A JP 2002-142399 A

  The present invention has been made in view of these points, and can be made thinner than conventional bobbins made of synthetic resin, thereby improving physical properties such as line area ratio and heat dissipation. It is an issue to provide.

  The present invention has been made to solve such a problem. In the bobbin having the flange portions 2 on both sides of the bobbin body portion 1 around which the winding is wound, the bobbin body portion 1 and the flange portion 2 are provided. Provided is a motor bobbin comprising an insulating paper, and at least a surface of the bobbin body portion 1 and the flange portion 2 made of the insulating paper which are in contact with a winding is made of an aromatic polyamide fiber. It is.

  The insulating paper constituting the bobbin body part 1 and the collar part 2 has a structure in which, for example, heat-resistant sheets 9 and 9 made of aromatic polyamide fibers are provided on both front and back sides of the base material 8 via adhesives 10 and 10. Things can be used.

  The collar part 2 can be bonded to the bobbin body part 1 via, for example, a glue margin part. In that case, the collar part 2 extends from the collar part 2 and is integrally formed with the collar part 2. Can be used as a glue margin.

  The adhesive margin part and the bobbin body part 1 can be bonded via an adhesive 11. As the adhesive 11, for example, an adhesive of the same material as the adhesive 10 between the base material 8 and the heat-resistant sheet 9 is used. Can be used.

In the bobbin having the flanges on both sides of the bobbin body portion around which the winding is wound as described above, the present invention is formed of a synthetic resin because the bobbin body portion and the flange portion are formed of insulating paper. As compared with the conventional bobbin, it can be formed thinner, and as a result, there is an effect that physical properties such as the bobbin line area ratio and heat dissipation can be improved.
Moreover, since at least the surfaces of the bobbin body portion and the collar portion made of insulating paper that come into contact with the winding are made of aromatic polyamide fiber, the surfaces of the bobbin body portion and the collar portion that are in contact with the winding at least slip. Therefore, when the winding is wound around the bobbin, there is an effect that there is no fear that the coating material (enamel etc.) of the winding is damaged.

  In addition, as the insulating paper constituting the bobbin body part and the collar part, in the case of using a structure comprising a heat-resistant sheet made of an aromatic polyamide fiber on both the front and back sides of the base material via an adhesive, the insulating paper is used. Since the base material, the adhesive on both sides, and the heat-resistant sheet on both sides have a five-layer structure, the insulating paper has a waist strength suitable for processing such as bending and molding. Therefore, there is an effect that it is possible to easily perform processing such as bending and molding of the insulating paper in configuring the bobbin.

  In addition, when the collar portion is bonded to the bobbin body portion via the glue margin portion, and the glue margin portion is extended from the collar portion and used integrally with the collar portion, The shape of the unfolded state of the insulating paper constituting the bobbin body part and the collar part which are separate bodies is also simplified, and there is an effect that the structure and assembly can be easily performed.

  Furthermore, when the adhesive part and the bobbin body part are bonded via an adhesive, and the adhesive of the same material as the adhesive between the base material and the heat-resistant sheet is used as the adhesive, heat resistance is required. Since the same characteristics as the adhesive, which is a constituent member of the insulating paper that constitutes the bobbin to be installed in the place, can be obtained without inadvertent peeling between the glue margin part and the bobbin body part. Adhesiveness between the margin part and the bobbin body part can be maintained.
