CSR electric successfully developed the world's leading high-speed permanent magnet variable frequency motor system Zhuzhou, April 28 after nearly half a year of intensive research, healthy antibacterial materials are a new trend in the development of home appliances. This morning, the internationally advanced high-speed permanent magnet variable frequency motor system was successfully rolled off the assembly line in CSR Zhuzhou Electric Co., Ltd, Provide cutting-edge power to the steam compressor newly developed by Hebei Leheng Chemical Equipment Manufacturing Co., Ltd. in some places to reduce the production capacity of enterprises in proportion

it is understood that the motor has a rated power of 165KW and a rated speed of 18000 rpm. It takes only 9 seconds to accelerate from Startup to rated speed. The whole power system has excellent performance, stable operation, low noise, small vibration and low life cycle cost. Compared with the traditional three-phase asynchronous motor supporting speed increasing box system, the energy utilization efficiency is increased by about 15%, which indicates that CSR Electric has fully mastered the core technology of high-speed permanent magnet variable frequency motor system and has become the terminator of the monopoly position of International Motor giants in this field. It provides the most advanced and revolutionary power system solution for China's fluid machinery to achieve energy conservation and environmental protection, and has milestone significance for CSR electric to further develop the high-speed fluid machinery motor market and cultivate new industries

yancaisong, manager of permanent magnet motor R & D Department of CSR motor technology center, said that the high-speed permanent magnet variable frequency motor system successfully developed this time includes motor, frequency converter and high-speed sliding bearing. It is the first time that the company has independently developed and realized the system integration of permanent magnet motor, frequency converter and high-speed sliding bearing on the basis of high-speed permanent magnet motor supporting large central business air conditioning. The whole system adopts the high-speed permanent magnet synchronous frequency conversion speed regulation technology, and the motor directly drives the compressor to run. Compared with the traditional three-phase asynchronous motor which drives the compressor through the gearbox, the speed increasing gearbox is omitted, thus eliminating the power loss, noise and vibration caused by the gearbox. The structure is compact, the maintenance is simple, and the volume of the power system is greatly reduced, It saves the installation space of the machine and the workload and use cost of later maintenance. Due to the increase of motor speed, compared with the three-phase asynchronous motor with the same power, the high-speed permanent magnet motor has greatly reduced the volume, weight, material consumption, the volume of the driven compressor and the cost, thus making the whole steam compressor have the advantages of high efficiency, high reliability and high power density

CSR motor, as the leader of traction power in China's rail transit, independently developed China's first tq-600 permanent magnet synchronous traction motor for high-speed EMUs in 2013, with excellent performance in operation assessment. The successful development of the high-speed permanent magnet variable frequency motor system highlights the international advanced level of CSR motor in the research technology, manufacturing process and test capability of permanent magnet motor. Due to the high cost performance and high-quality service, more than 20 well-known domestic and foreign high-speed fluid machinery enterprises have carried out technical cooperation with CSR motor, forming a series of product types ranging from 50KW to 1200kW. With the successful development and promotion of various high-speed permanent magnet motors, it has great economic and social benefits

it is reported that Hebei Leheng Chemical Equipment Manufacturing Co., Ltd. is a high-tech enterprise specialized in the R & D, design, manufacturing, installation and commissioning of MVR (mechanical vapor recompression) evaporative crystallizer, turbomachinery and heat recovery system. The company's energy-efficient blowers, compressors and other products are used in pharmaceutical, food, chemical It is widely used in environmental protection and other industries
