UPTEC List of Products and Services

On this page, you can download case materials for "Prototype of U-shaped hairpin stator samples." 【Challenges and Background of the Customer】 ■ Looking to mass-produce stators, the customer hopes to prototype various sample variations that meet different specifications and standards. ■ The need for advanced production techniques, such as special processing of copper wire, is a challenge. ■ Particularly, there are very few companies in Japan that can handle X-pin shapes, making it difficult to select a prototyping partner. I believe there are few companies in Japan capable of prototyping X-pins. Our company has a track record of orders from several major domestic companies and is especially well-regarded for our manufacturing technology of flat rectangular wire hairpins, so please feel free to consult with us. We will respond to specifications and requirements based on the customer's development stage and objectives. Considering applications, costs, and delivery times, we will proceed with prototyping in the best possible manner. ＼ For detailed case information, please check by downloading the catalog ／

We would like to introduce our "stator sample prototyping" services. Generally, as part of the mass production plan, prototypes of "samples by development phase (so-called A, B, C samples)" are created. After prototyping and verifying the initial A sample, B samples (for performance and functionality verification) are designed and prototyped based on the issues identified. Furthermore, taking the results into account, C samples (prototypes close to mass production specifications) are prototyped, which is a typical phased development flow. 【Features】 ■ We have received orders from several major domestic companies, and we are particularly confident in our high production technology using hairpin flat wire. ■ We have experience in producing stators using not only copper wire but also aluminum flat wire. ■ While we do not have experience in prototyping W pins, it may be possible depending on the request. ■ Production of X pin stator assemblies. ■ Evaluation of forming and welding of aluminum flat wire. ＼ For more details, please check "Download Catalog" ／

Are you struggling with the challenges of welding evaluation due to insufficient equipment and manpower? Our company offers services that cater to both laser and TIG welding methods, focusing on the evaluation of welding for components such as coil ends and connection plates (busbars). We provide services that include confirming the strength of welds, measuring the weld cross-section to check the amount of fusion, and evaluating welding matrices, all with excellent cost performance. 【Examples of Challenges】 - We want to conduct welding evaluations for coil ends and connection plates (busbars) of stator assemblies, but we lack the necessary equipment in-house. - We want to perform welding evaluations, but we do not have the resources internally. - We want to test new methods or shapes (such as X-pins), but the risks are high, and we would like to utilize external support. 【Service Features】 - We support both laser and TIG welding, enabling a variety of welding evaluations. - We provide evaluation results within the shortest time frame of 5 business days, including tensile tests and weld cross-section evaluations. - We have extensive evaluation experience with various shapes such as hairpins and X-pins, as well as materials like copper and aluminum flat wires. *For more detailed information, please feel free to contact us through our inquiry form or website.*
