Description

Combined motor set with multiple single-tooth assemblies Child and its manufacturing method

The present invention relates to a combined motor stator and a method of manufacturing the same, and more particularly to a motor stator by which a plurality of single-tooth assemblies are assembled and a method of manufacturing the same.

Since the development of the motor industry in the 18th century, it has been widely used in people's lives. Whether in the traditional industry or the technology industry, the shadow of the motor can be seen. The motor uses the principle of Ampere's law to pass current through the coil and generate a magnetic field. The stress is generated by the interaction between the induced magnetic field and the permanent magnet. Therefore, electric power can be converted into a stress via the motor.

Typically a motor includes a stator and a rotor. In terms of the stator, in order to increase the slot ratio of the coil in the motor to increase the efficiency of electromagnetic conversion; in addition, in order to make the winding easier, so that the motor is made easier, people have continuously invented different types of stator structures. .

Referring to the first figure, the first figure shows a schematic diagram of a spliced motor stator assembly provided by the first prior art. as the picture shows, The spliced motor stator is described in Japanese Patent Laid-Open Publication No. 2005-130605, and the spliced motor stator PA100 includes a plurality of motor single-tooth structures PA1. Each motor single-tooth structure PA1 includes a first assembly portion PA11, a second assembly portion PA12, and a winding winding portion PA13. The windings PA2 are first wound around the winding winding portion PA13, and the first grouping portion PA11 is first connected to the second grouping portion PA12. In this way, the motor single-tooth structures PA1 can be combined with each other to form the spliced motor stator PA1O0.

After the splicing motor stator PA100 is implemented, a motor stator having a high slot ratio can be produced. However, when the first set of the joints PA11 and the second set of the joints PA12 are aligned and assembled, it is more difficult to accurately assemble the positioning. Because in the manufacture of the motor single-tooth structure PA1, the respective steel sheets constituting the motor single-tooth structure PA1 are inevitably subject to manufacturing tolerances. In particular, the tolerances on the regions of the first set of joints PA11 and the second set of joints PA12 corresponding to the respective steel sheets, such that the first set of joints PA11 and the second on the assembled motor single-tooth structure PA1 The assembly portion PA12 produces a cumulative tolerance. As a result, it may be difficult to form the spliced motor stator PA100 by assembling the first set portion PA11 and the second set portion PA12, thereby increasing the difficulty of fabrication.

In addition, the direction in which the motor single-tooth structure PA1 is assembled and the direction in which the motor single-tooth structure PA1 is combined is the axial direction. Therefore, when the motor single-tooth structure PA1 is assembled, the motor single-tooth structure PA1 is easily deformed. . Moreover, when the frame is assembled, the direction of the frame of the spliced motor stator PA100 is also aligned with the direction in which the motor single-tooth structure PA1 is assembled, thereby increasing the processing difficulty.

Referring to the second drawing, the second drawing shows a schematic view of a single-toothed chain motor stator provided by the second prior art. As shown in the figure, the single-tooth chain motor stator PA3 is formed by a plurality of chain single-tooth structures PA31. Among them, after the single-tooth chain type motor stator PA3 is used, since the winding and the wire are easy to be wound, the process is simplified, and the time required for the processing is reduced. In addition, the grouping direction of the single-tooth chain type motor stator PA3 is different from that of the sheet metal stamping and the frame-injecting direction, so that deformation is less likely to occur.

However, since the single-tooth chain type motor stator requires high machining accuracy, it is necessary to use individual corresponding jigs when assembling. Moreover, not only the stamping die used is bulky, but also a lot of waste generated by the stamping process. Therefore, the use of a single-tooth chain motor stator can cause a number of problems.

In view of the first prior art, when the spliced motor stator is aligned and the first set of joints and the second set of joints are assembled, the cumulative tolerances generated by the first set of joints and the second set of joints are increased. The difficulty of assembling the first set of joints and the second set of joints increases the difficulty of production. In addition, the direction in which the motor single-tooth structure is assembled, the direction in which the steel sheet forming the single-tooth structure of the motor and the direction of the frame of the combined motor stator are the same as the axial direction, so that the single-tooth structure of the motor is easily deformed, thereby increasing The processing difficulty.

In addition, the single-tooth chain type motor stator provided by the prior art requires high processing precision, so it is necessary to use an individual corresponding treatment. With. Not only is the stamping die used large in volume, but the scraping process produces more waste.

The present invention solves the problems of the prior art, and the necessary technical means is to provide a combined motor stator that combines a plurality of single-tooth assemblies, and includes a plurality of single-tooth assemblies.

Additionally, the first curved outer periphery and the second curved outer periphery define a circular outer periphery of the combined motor stator.

Each of the first engaging structures is a snap protrusion or a snap groove. Each of the second engaging structures is an engaging groove or an engaging protrusion corresponding to one of the first engaging structures. That is, if the first engaging structure is a snapping bump, the second engaging structure is a corresponding engaging recess. If the first engaging structure is an engaging groove, the second engaging structure is a corresponding engaging protrusion. Preferably, the engaging projection is a one-side projection, and the engaging groove is a one-shaped groove.

In addition, when the first silicon steel sheet and the second silicon steel sheet are tightly riveted, the following two technical means can be used. Achieve the purpose of the combination. The first technical means is that the first riveting structure is a convex riveting structure provided to the second riveting structure, and the second riveting structure is a concave riveting structure; the second technical means is that the first riveting structure is one The recessed riveted structure and the second riveted structure is a condition of a convex riveted structure disposed toward the first riveted structure; wherein the recessed riveted structure may be a riveted groove or a riveted hole.

In terms of the detailed structure, the first body portion and the first extending joint portion have a first body extending minimum width in the first arc extending direction, and the first winding portion has a first direction along the first arc extending direction. The maximum width of a winding, the minimum width of the first body extension is greater than the maximum width of the first winding. In this way, the winding group does not leave the first winding portion.

Similarly, the second body portion and the second extension joint portion have a second body extending minimum width in the second arc extending direction, and the second winding portion has a second winding direction in the second arc extending direction. The maximum width, the second body extension minimum width is greater than the second winding maximum width. In this way, the winding group does not leave the second winding portion.

In the technical means necessary for the present invention, a method of manufacturing a combined motor stator in which a plurality of single-tooth assemblies are assembled is further provided. In order to manufacture a combined motor stator in which a plurality of single-tooth assemblies are assembled, first, a first silicon steel sheet and a second silicon steel sheet are joined, and the first extension joint portion is formed into a first engagement structure, and is formed at the second extension joint portion.

Compared with the prior art, after implementing the combined motor stator and the manufacturing method thereof provided by the present invention, since the two partial combined motor stators are assembled, the angle between the twisting direction and the riveting direction and the axial direction is different. Therefore, it is less likely to be deformed when assembling the combined motor stator. The two single-tooth assemblies can be engaged only by engaging the first engaging structure with the second engaging structure. Therefore, when assembling a plurality of single-tooth assemblies, it is less difficult to make the assembly difficulty due to the tolerance generated when the single-tooth assembly is made. In addition, the present invention only needs to stamp two sets of silicon steel sheets, which are a first silicon steel sheet and a second silicon steel sheet, respectively. Therefore, the fixtures that need to be used are more Simply, there is less waste generated during the production process.

In summary, the present invention not only avoids the tolerances produced by the prior art in the production of silicon steel sheets, but also reduces the chance of deformation of the single-tooth assembly. In addition, the present invention also reduces waste generated during production. Therefore, the present invention surely solves the problems faced by the prior art.

In detail, the assembly mode can fix the partial combined motor stator 10b, and the partial combined motor stator 10a can be twisted in the torsional direction RO to be combined with the partial combined motor stator 10b. The partial combined motor stator 10b may be assembled in a manner opposite to the torsional direction RO and the partial combined motor stator 10a may be coupled to the partial combined motor stator 10b in the torsional direction RO. Further, the partial combined motor stators 10a and 10b are generally semi-annular motor stators, but are not limited thereto.

Compared with the prior art, after implementing the combined motor stator and the manufacturing method thereof provided by the present invention, since the two partial combined motor stators are assembled, the angle between the twisting direction and the riveting direction and the axial direction is different. Therefore, it is less when assembling the combined motor stator Easy to deform. The two single-tooth assemblies can be engaged only by engaging the first engaging structure with the second engaging structure. Therefore, when assembling a plurality of single-tooth assemblies, it is less difficult to make the assembly difficulty due to the tolerance generated when the single-tooth assembly is made. In addition, the present invention only needs to stamp two sets of silicon steel sheets, which are a first silicon steel sheet and a second silicon steel sheet, respectively. Therefore, the jig to be used is relatively simple, and the waste generated during the production process is also small.

In summary, the present invention not only avoids the tolerances produced by the prior art in the production of silicon steel sheets, but also reduces the chance of deformation of the single-tooth assembly. In addition, the present invention also reduces waste generated during production. Therefore, the present invention surely solves the problems faced by the prior art.

The features and spirit of the present invention will be more apparent from the detailed description of the preferred embodiments. On the contrary, the intention is to cover various modifications and equivalents within the scope of the invention as claimed.
