JFE Techno-Research Corporation (Headquarters: Chiyoda-ku, Tokyo; President: Kazuhiro Seto) is launching a new solution to address the increasing rotational speeds of EV drive units. This is achieved by integrating the specialized motor evaluation technology developed by JFE Techno-Research—based on material evaluation and measurement techniques cultivated in the steel industry—with the high-speed motor dynamo testing technology provided by Technical Support Co., Ltd. (Headquarters: Hamamatsu, Shizuoka; President: Masazumi Yamamoto). This technology captures high-speed footage of the actual behavior of cooling and lubricating oil supplied to gears in high-rotation environments of up to 24,000 rpm, and evaluates this data in combination with numerical analysis (fluid analysis), providing new insights for cooling and lubrication design under high-rotation conditions, where development is expected to accelerate. [Background and Technical Features] In recent years, the drive for smaller units to increase the flexibility of vehicle body design has led to rapid advancements in high power density and miniaturization of the motors, inverters, and reduction gears that make up e-Axles. Since motor output is the product of torque and rotational speed, the industry as a whole is accelerating the shift toward higher motor speeds to achieve weight reduction and higher efficiency. On the other hand, higher speeds create numerous technical challenges, including heat generation, vibration, insulation, and strength, making the optimization of gear cooling and lubrication a critical theme. The primary feature of this new solution is the ability to visualize and improve the analytical accuracy of gear cooling and lubrication mechanisms. By utilizing the high-speed dynamo testing technology held by Technical Support Co., Ltd., along with the specialized measurement using high-speed cameras and fluid analysis technology held by our company, we can observe in detail how cooling oil drippe
