Stretching and circular machinery shells: innovation and application of motor protection technology
In the modern industrial system, micro-motors are everywhere, and the motor shell is its protection body, and its manufacturing process and material selection are directly related to the performance, life and reliability of the motor. Stretching and rounding technology has become a mainstream production process, and enterprises such as Zhejiang Yadong have become important production enterprises in this field thanks to their technological accumulation and production experience.
The traditional motor shell is made of seamless steel pipe, which is expensive and inefficient. With the advancement of technology, the tensile and circular molding process gradually replaces the traditional processing methods, and the new process produces the chassis with the advantages of light weight, high strength, and good heat dissipation, while greatly improving the production efficiency and reducing the production cost.
The tensile case is mainly made of aluminum alloy and stainless steel. The aluminum alloy tensile motor shell has the advantages of light weight, high strength, good heat dissipation, corrosion resistance, inner chamber free from cutting, etc.The aluminum alloy motor shell material of hot extrusion usually adopts the national standard 6063 aluminum alloy material, and the concentricity of the inner hole can reach the high-precision standard of ≤ 0.07 mm. Stainless steel tensile motor shells focus on higher strength requirements, and their corrosion and wear resistance are better, suitable for harsh working environments.
The coil machinery shell is molded using the coil and coil plate process, and the main material varies according to the diameter of the shell. The production process comprises a number of processes such as falling material, dispersing heat holes, pressing circles, closing, and plasticization. The workpiece material is usually 08F steel plate, which has good ductility and magnetic conductivity, and is most suitable for small power motor casing. The advantage of rolling machine shells is high production efficiency, suitable for high volume production, and relatively low cost.
The material selection of the motor shell needs to consider factors such as the working environment, heat dissipation requirements, mechanical strength and production costs. In terms of structural design, modern motor shells use innovative designs to improve performance, such as high-strength stainless steel stretching motor shells that include cylindrical bodies, fixed pillars and heat dissipation sheets, which ensure structural strength and provide good heat dissipation.
The applications of Stretch and Wrap are very wide, covering many fields such as environmental air conditioning, electric vehicles, servo motors, CNC, wind power generation and so on. With the rapid development of new energy resources automobile industry, the demand for motor shell will further increase.
Zhejiang Yadong, as an industry representative company, has accumulated rich experience and technical advantages in stretching and rolling machine shells, solving technical difficulties such as the easier recoil deformation of aluminum alloy motor shell after the internal pore adjustment, and providing higher-quality products for motor manufacturers.
In the future, with the continuous development of motor technology, motor shell manufacturing will evolve toward more sophisticated size control, more efficient heat dissipation design and lighter weight, providing more solid and reliable assurance for the motor industry.
