• Secondary Cells/Batteries

【Application】 The rotational speed of motors used in electric vehicles and home appliances is on the rise, leading to an increased demand for covers that prevent damage or detachment of the rotor's permanent magnets in order to ensure the functionality of the motors from a redundancy perspective. Additionally, this cover is required to be thin to minimize the air gap between the coil and the magnet, thereby reducing magnetic loss and achieving lightweight rotors. Endo Manufacturing offers a thin and lightweight "Motor Rotor Protection Cover" made from non-magnetic stainless steel, processed with unique technology for metal sleeves. 【Features】 - The material used is the highly versatile non-magnetic stainless steel SUS316L. - The manufacturing method employs deep drawing and stretching processes through pressing. By combining spinning methods, further precision can be achieved. - The shape can accommodate pipe shapes or bottomed shapes depending on the assembly method.

【Application】 With the ultra-high-speed operation of motors for electrical devices such as electric vehicles and electric compressors, high centrifugal forces are generated in the rotor and permanent magnets. As a result, there are cases where non-magnetic nickel alloys and titanium alloys, which have high mechanical strength, are used as reinforcing materials for permanent magnets, processed into metal sleeves. However, the high material costs of these options pose a challenge. Endo Manufacturing Co., Ltd. offers a high-strength, high-precision "Rotor Reinforcement Sleeve for Motors," processed using proprietary technology with non-magnetic stainless steel. 【Features】 - The material used is SUS316L, a highly versatile non-magnetic stainless steel. For cases requiring even higher strength, high-strength non-magnetic stainless steel materials are also available. This allows for a reduction in material costs compared to nickel alloys and titanium alloys. - The manufacturing method employs spinning technology, achieving high strength through the effects of work hardening that cannot be obtained through machining. - The shape can accommodate pipe shapes or bottomed shapes depending on the assembly method.

The power transmission method in precision machinery mainly uses gears; however, alternatives to gears are being sought in terms of transmission accuracy and dust prevention. Metal belts are known as a power transmission method that addresses the challenges posed by gears, but due to issues with workability and strength, it is currently difficult to produce low-cost, high-strength metal belts. Endo Manufacturing has developed a unique processing method to manufacture metal ultra-thin seamless pipes (metal sleeves). With this technology, they have succeeded in producing metal belts with fatigue strength 30% higher than conventional metal belts, while also reducing costs by 50%. The technology for metal sleeves enables the mass production of ultra-thin metal belts with a thickness of less than 30μm. We are pleased to present technical documentation on the production of ultra-thin metal belts (seamless belts) that can be produced with high strength and low cost!

Our company's metal sleeves utilize technology that processes metallic seamless pipes to an extreme thinness, showcasing the pinnacle of metal plastic processing technology unique to Endo Manufacturing. Thin-walled seamless pipes (laminated type) are created by layering metals on the surface of thin-walled seamless pipes processed with metal sleeve technology, according to their intended use. For example, by layering highly thermally conductive aluminum on top of a thin-walled seamless pipe made of high-strength stainless steel, it becomes possible to achieve a seamless pipe that possesses both the strength of stainless steel and the thermal conductivity of aluminum. By layering a highly thermally conductive dissimilar metal on the surface of a thin-walled seamless pipe made of stainless steel, we significantly enhance the thermal conductivity of the seamless pipe. *For more details, please download the materials or contact us.*
