UPTEC List of Products and Services

We would like to introduce our "stator sample prototyping" that we conduct. 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 common step-by-step development flow. 【Features】 ■ We have received orders from several major domestic companies and are particularly confident in our production technology using hairpin flat wire. ■ We have production experience using aluminum wire instead of copper wire. ■ While we do not have prototyping experience with W pins, it may be possible depending on the request. ■ X pin stator assembly production. ■ Evaluation of forming and welding of aluminum flat wire. ＼ For more details, please check "Download Catalog" ／

On this page, you can download case materials for "Prototype samples of X-pin shaped stators." [Challenges and Background Faced by the Customer] - Considering mass production of stators, the customer was looking into prototype variations that could accommodate various specifications and standards. - Particularly for the X-pin shape, there are limited companies in Japan capable of handling prototypes. - There were concerns about delays in the development schedule and the difficulty of technical responses. I believe there are few companies in Japan that can prototype X-pins. Our company has a track record of orders from several major domestic companies and is especially renowned for its manufacturing technology of flat rectangular wires, so please feel free to consult us. ＼ For detailed case information, please check "Download Catalog" ／

On this page, you can download case materials for "U-pin shaped stator sample prototyping." 【Challenges and Background Faced by the Customer】 ■ With an eye on mass production of stators, the customer hopes to prototype variation samples that meet various specifications and standards. ■ The need for advanced production techniques, such as special processing of copper wire, is a challenge. ■ Particularly for the X-pin shape, there are very few companies in Japan that can accommodate this, 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 we are particularly well-regarded for our hairpin manufacturing technology using flat wire, so please feel free to consult with us. We will respond to specifications and requirements based on the customer's development stage and objectives. Taking into account applications, costs, and delivery times, we will proceed with prototyping in the best possible way. ＼ For detailed case information, please check by downloading the 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.*

To achieve both weight reduction and cost savings for EV motors, stator technology using aluminum flat wire is gaining attention. Accordingly, our company is conducting prototype development with an eye toward switching from copper wire to aluminum wire. 【Features】 - Achieves approximately 30-40% weight reduction compared to copper wire - Supports both TIG and laser welding, ensuring high conductivity performance Our company has handled numerous EV motor manufacturing lines, and leveraging that experience, we are actively participating in challenging projects such as the prototyping of aluminum flat wire stators. We optimize the "wire forming conditions and welding conditions" that differ from copper wire, and we can also discuss coil end shapes (such as Xpin, Upin, and special shapes) tailored to customer requests. Amid rising copper prices and increasing demands for weight reduction, our company has established unique technologies to address the specific challenges of aluminum in each process from stator structural design, forming, to welding, and we welcome inquiries starting from the stage of "I would like to try an A sample first." *For more detailed information, please feel free to contact us via the inquiry form or our website.
