A new wire that contributes to high output, high efficiency, and miniaturization of EV drive motors.
In the EV drive motor industry, there is a demand for higher output, higher efficiency, and miniaturization of motors to improve vehicle performance and save space. In particular, when designing the stator coil, which affects motor performance, it is important to arrange a large amount of copper wire in a limited space and reduce energy loss. Conventional round and rectangular wires have limitations on the coil's filling factor, which can constrain improvements in motor performance. Our ultra-deformed wire is a specially designed irregular wire developed to address these challenges. 【Application Scenes】 - Stator coil winding for EV drive motors - Development of high-efficiency motors - Design of compact and lightweight motors 【Benefits of Implementation】 - Improved motor filling factor (over 80%) - Achievement of higher output and higher efficiency - Contribution to the miniaturization and lightweighting of motors ＼*For more details, please download the PDF document below or feel free to contact us／

basic information
【Features】 - The use of special shaped wire improves the filling factor of the stator coil to over 80%. - By gradually changing the thickness and width without altering the cross-sectional area, a tapered stator coil is formed. - Gaps between the stator cores are filled, achieving a high filling factor. - Depending on the design, it can be applied to miniaturization by reducing the gaps between stator coils. - Contributes to the development of high-performance motors that are high output, high efficiency, compact, and lightweight. 【Our Strengths】 Since our establishment in 1947, we have specialized in the manufacturing of shaped wire through wire drawing and rolling processes, enabling us to provide a consistent production of unique metal components utilizing shaped wire. Our manufacturing through plastic processing results in excellent toughness, strength, and smooth surface characteristics, allowing us to offer product specifications tailored to customer needs while leveraging cost advantages. We also have a wealth of experience in supplying automotive parts and contribute to solving customer challenges in the development of EV drive motors.

Company information
Since its establishment in 1947, we have been manufacturing and selling steel wire products through drawing and rolling processes, and now we offer integrated production from cold-formed components to metal parts produced by pressing, shearing, and machining. In particular, we excel in the production of deformed coil wire with irregular cross-sections, and our strength lies in our ability to consistently produce unique deformed metal parts utilizing these irregular wires. Compared to powder sintering and precision casting methods used for manufacturing deformed parts, our deformed metal parts produced entirely through plastic processing at Namitei possess excellent toughness, strength, and smooth surface characteristics, making them widely adopted in sliding components and thin-walled deformed parts. To leverage the cost advantages of continuous processing, we propose specifications that mix functional applications and processing characteristics to meet our customers' needs.
