Abstract

PURPOSE:To protect the winding work and slot insulating paper when winding is performed, by arranging to wind to both end faces of a core an end plate into which a spool to enclose the winding coil and a pad to receive the slot insulating paper situated at the bottom of the slot are integrally formed. CONSTITUTION:Firstly, an end plate 10 is arranged to both end faces of a core 1 into which a spool 8 and a pad 9 are integrally formed. Slot insulating paper 4 is inserted into a slot 3. Then, a winding coil 2 is wound in predetermined winding number to the spool 8 of the end plate 10 with initial winding coils 5a and 5b fixed. At this moment, the pad 9 formed at the bottom of the slot 3 becomes a cradle, so that the deformation of the slot insulating paper is prevented. Thus, the winding coil 2 is ensured to be tightly wound and the insulating paper 4 is prevented from being deformed or torn off due to the tension of the coil 2 when winding is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a field assembly for a motor used in home appliances, power tools, and the like.

BACKGROUND OF THE INVENTION Various improvements have been made in field assemblies to streamline windings. The challenge was how to wind the wires in a way that would prevent coil disturbances.

Hereinafter, the conventional field assembly as described above will be explained with reference to the drawings.

FIG. 3 shows a conventional field assembly.

In FIG. 3, 1 is a core serving as a magnetic path.

Reference numeral 2 denotes a winding coil, which is wound within the slot 3 of the core 1 with a slot insulating paper 4 interposed therebetween. 5a and 5b are winding coils 2
This is the coil at the beginning of winding. Similarly, 6a and 6b are coils with 20 windings completed.

7 is a tie thread for fixing the winding coil 2 after winding.

The field assembly configured as described above is incorporated as a field of a motor, and the winding end coil 6a.

6b is used as a power source Hiji line.

Further, the winding start coils 5a and 5b are each connected to a brush as a brush day wire.

Problems to be Solved by the Invention However, in the above configuration, it is necessary to fix the winding coil 2 with a tie string 7 or the like in order to prevent it from coming apart. Further, since the armature (rotor) is inserted during assembly, it is necessary to shape the coil to ensure the inner diameter dimension of the winding coil 2, which requires labor after winding.

Furthermore, during winding, a large force is applied to the bottom of the slot insulating paper 4 due to the tension of the winding coil 2, which causes tearing and deformation, which causes defects.

In view of the above-mentioned problems, the present invention provides a field assembly that has a simple structure and is capable of winding work and protecting slot insulating paper during winding.

Means for Solving the Problems In order to achieve this object, the field assembly of the present invention has a plurality of winding frame parts for housing the winding coils and a pillar part of the X-lot insulating paper receiver located at the bottom of the slot. End plates formed integrally are placed on both end faces of the core assembly, and the wire is wound after inserting strip insulation paper.

Function: With this configuration, by winding the coil around the winding frame, it is possible to prevent the coil from coming loose or falling inward. Furthermore, by forming the pillar portion located at the bottom of the slot, the slot insulating paper is prevented from being damaged or deformed due to the tension of the coil during winding.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. Here, FIG. 1 shows the field assembly of the present invention.

In Figure 1,] - is the core, 2 is the winding coil, 3 is the slot, 4 is the slot insulating paper, 5 a + 5 b is the starting coil, 6 a and 5 b are the ending coils, and hereafter F
is the same as the configuration shown in FIG. 8 is a winding frame portion in which the winding coil 2 is housed, and 9 is a column portion 9 located at the bottom of the slot 3.
It is. The winding frame portion 8 and the pillar portion 9 are integrally formed with an end plate 10 made of electrically insulating synthetic resin.
0 are placed on both end faces of the core 1. FIG. 2 shows an end plate used in the field assembly of the present invention.

The assembly procedure for a field assembly configured like a ridge will be described below.

First, an end plate 10 having a winding frame part 8 and a pillar part 9 integrally formed on both end faces of the core 1 is placed 2, and a slot insulating paper 4 is inserted into the slot 3. After that, the beginning of the volume 2I 5a,
5b is fixed, and the winding wire 2 is wound around the winding frame portion 8 of the end plate 10 by a predetermined number of turns. At this time, the slot insulating paper 4 serves as a support for the pillar portion 9 formed at the bottom of the slot 3 to prevent the slot insulating paper 4 from being deformed.

According to this embodiment, the winding coil 2 can be reliably and securely wound by forming the winding frame part 8 on the end plate 10 disposed on both end faces of the core 1, thereby preventing unraveling and The problem of falling inward is solved, and at the same time, by forming the column part 9 at the bottom of the thrower l- to receive the slot insulating paper, the tension of ':1 ile 2 during winding (
By preventing deformation and tearing of the insulating paper 4 due to the winding, furthermore, there is no need to fix the winding coil 2 with a tie string or the like, which improves work efficiency and is rational.

Effects of the Invention As described above, the present invention has end plates on both end faces of the core in which the pillars of the insulating paper receivers of the staggered slots are integrally formed at the bottoms of the upper slots of the plurality of winding frames in which the winding coils are housed. The winding structure ensures that the winding coil is securely attached to the winding frame.
Since it can be wound, problems such as the :1 coil coming apart or falling inward after winding and reducing the inner diameter dimension are also solved. In addition, by forming a pillar portion to receive the slot insulating paper at the bottom of the slot where the highest force is applied during winding, it is possible to prevent defects such as deformation and tearing of the insulating paper due to the tension of the coil. Furthermore, in the past, after winding, it was necessary to manually fix the coil end tightly with a string, but with the field assembly of the present invention, the entire process can be completed with just the winding. It has great practical effects, such as improved productivity, reduction in the number of T-pieces, and rationalization.
