Motor rotor reinforcement sleeve - Prevents magnet damage

Developed a rotor reinforcement sleeve using non-magnetic stainless steel as a countermeasure against motor magnet damage. Achieving high strength, high precision, and low cost.

【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.
