Low-temperature centrifuge companies need to intensify their efforts in technological innovation.

　　 Low-temperature centrifuge As market demand continues to grow, industries must intensify their efforts in technological innovation, integrate scientific and technological resources, and leverage major science and technology programs to break through bottlenecks in core and key technologies. In addition, it is essential to strengthen the development of industrial talent teams—including entrepreneurial teams, professional technical talent teams, industrial worker teams, and industrial talent reserves—to provide a solid talent base for enhancing independent innovation capabilities and improving the overall quality of the industry.
　　Low-temperature centrifuges are widely used in the medical industry. They are essential for a variety of applications, including blood separation, virus research, DNA studies, and drug purification. At the microscopic level, cells and DNA molecules both require low-temperature centrifuges for separation and analysis. These high-speed, low-temperature centrifuges typically operate at speeds ranging from over 5,000 to under 60,000 revolutions per minute, generating centrifugal forces that can be tens of thousands of times greater than Earth's gravitational acceleration, enabling the separation of even the tiniest molecular particles. For blood separation, a centrifuge operating at around 3,000 rpm is usually sufficient; currently, most manufacturers can produce such equipment, and they have proven highly effective in practical applications. In contrast, centrifuges used in drug purification and other refining processes are generally low-speed, low-temperature models, with rotational speeds below 3,000 rpm. These centrifuges have large processing capacities and, to meet GMP standards and requirements in pharmaceutical production, are typically constructed from flat, stainless steel materials.
　　Driven by the rapid advancement of biomedicine in recent years, low-temperature centrifuges have also achieved significant progress and have established a distinct market segment separate from conventional centrifuges. It is expected that this growth momentum will continue in the future, attracting more research institutions to enter the market. Meanwhile, low-temperature centrifuges are also among the fastest-growing product categories in the centrifuge industry in terms of technological development. Low-temperature centrifuge The rated power of an electric motor refers to the maximum mechanical power that the motor can continuously output under standard ambient temperature (40℃), specified operating mode, and rated conditions, thereby ensuring its service life.
　　If all actual conditions are identical to the specified ones, as long as the rated power of the low-temperature centrifuge motor exceeds the actual power of the load, the steady-state temperature rise achieved during operation will approximate the rated temperature rise. This not only ensures that the motor’s heating conditions are fully utilized but also enables the motor to meet its specified service life. However, in practice, actual conditions often differ from the specified ones. Provided that the motor can still achieve its specified service life, if the actual ambient temperature differs from the standard ambient temperature, the actual duty cycle differs from the prescribed duty cycle, the actual short-time rating differs from the specified short-time rating, or the actual intermittent rating differs from the prescribed intermittent rating, then when selecting the motor’s rated power, we can first adjust the rated power accordingly—making it either lower than or higher than the actual load power.
　　Choosing an electric motor in this way ensures that its heating conditions are fully utilized without selecting an excessively high rated power, and also prevents the motor from operating under overload due to an undersized rated power, which could shorten its service life or even cause damage. For continuous-duty motors operating under continuous-duty conditions, when the actual ambient temperature q differs from 40℃, a correction factor must be applied to the motor’s rated power. Based on theoretical calculations and practical experience, at different ambient temperatures, Low-temperature centrifuge The rated power of the motor can be increased or decreased accordingly.
