On September 19, 2022, HNGC Permanent Magnet Power Technology Corporation, which was jointly established by ten leading enterprises in the permanent magnet power industry in China, including HNZZ Permanent Magnet Motor Technology Corporation and China NF Rare Earth Group, was officially established.
The company will promote the transformation and commercial application of permanent magnet power scientific and technological achievements in the model of collaborative innovation of the whole industry chain, and accelerate the enhancement of the core competitiveness of China's permanent magnet power technology industry.
As early as 2003, HNZZ began to develop permanent magnet power technology and products.
After years of technical reserves, HNZZ and other companies have trained a large number of industrial technical workers in the field of permanent magnet power application and drive, built a series of technical platforms, gradually improved the research and development system, and achieved remarkable results in applied research.
HNZZ has more than 400 core technical talents engaged in permanent magnet application research, and has initially formed an industrial chain integrating R&D, design, manufacturing, and after-sales service, with an output value exceeding 10 billion yuan.
According to Yan Caisong, chief technical expert of HNZZ, after more than 10 years of technical research and development and exploration, HNZZ has developed and produced more than 20,000 high-performance permanent magnet motors, many of which are running on rail transit.
"The permanent magnet power technology successfully applied in the field of rail transit can save about 30% of the main energy consumption compared to traditional asynchronous motors." Yan Caisong said that permanent magnet power has high efficiency, energy saving, green and low carbon, high power density, low noise, It has obvious advantages such as simple maintenance and is the technical representative of high efficiency, energy saving and green and low carbon development.
Permanent magnet traction motors have been used in high-speed EMUs, subways, and locomotives in China.
In the past five years, permanent magnet motors have accounted for more than 90% of electric vehicles; in the field of central air conditioners, the central air conditioners using high-speed permanent magnet direct drive variable frequency drive systems have reduced the volume by half and saved more than 40% of energy.
