Permanent magnet synchronous motor technical breakthrough in favor of the application field of ndfeb magnets
Permanent magnet synchronous frequency heat pump is based on the technical foundation of permanent magnet synchronous frequency centrifuge, specially designed and manufactured as per the heat pump working condition, permanent magnet synchronous frequency centrifuge technology represents the development direction of the central air conditioning.permanent magnet synchronous frequency heat pump is based on the technical foundation of permanent magnet synchronous frequency centrifuge, specially designed and manufactured as per the heat pump working condition, permanent magnet synchronous frequency centrifuge technology represents the development direction of the central air conditioning.
Recently the 26th China refrigeration exhibition held in Shanghai new international exhibition center. Gree electric appliances in introduced many new refrigeration and air conditioning, including Gree permanent magnet synchronous frequency conversion pump centrifuge, most experts are simply astounding.
Synchronous generator study duration is very long before, in order to realize the transformation of energy, need to have a dc magnetic field, and the generation of the magnetic field can be reached on rare earth permanent magnet materials, permanent magnet synchronous frequency conversion pumps centrifuge is based on permanent magnet synchronous frequency conversion centrifuges skills root, on heat pump working condition of special planning, questions to deal with the north heating supply excellent energy saving plan. Permanent magnet synchronous frequency conversion centrifuges skill represents the development direction of the central air conditioning.
Large public buildings with high energy consumption of the air conditioning system ,the energy saving potential is big, has long served as a key by attaches great importance to energy saving of the construction industry, large public buildings in China rapid growth at an annual rate of 3000 to 40 million square meters. In recent years, many manufacturers working on the chillers has carried on the positive exploration, and made great progress, improve the energy saving of the unit in different degree, but failed to make full performance (COP) and partial load performance (IPLV) at the same time to reach a higher level. And permanent magnet synchronous frequency conversion centrifugal unit has outstanding energy saving, reliability and adaptability, in a large office buildings, hospitals, schools, shopping malls and other large public buildings further highlight the superiority. Because of permanent magnet synchronous frequency conversion motor in the temperature reached a certain degree, the power requirement become low so as to achieve the aim of energy saving and compression refrigeration cycle.
Of course, permanent magnet synchronous motor not only used in air conditioning field, but also the field of rail transit, CSR launch of the permanent magnet synchronous transmission system, traction system. After that, the permanent magnet synchronous motor in the electric car, subway, high-speed emu, the application of good news in the lowland a scooter. Permanent magnet synchronous motor due to its small volume, light quality, has the absolute advantage in the unit of power density, so the electric car, robot, air conditioning, wind power, magnetic separation equipment and consumer electronics and other fields has a wide application.
NdFeB magnets as the best choice of the permanent magnet synchronous motor, such as high magnetic energy product, far higher than that of ferrite traditional remanent magnetism of permanent magnet and the intrinsic coercive force, become the mainstream of a new generation of high performance permanent magnet new material. Except iron in ndfeb, still need to add neodymium and dysprosium, terbium rare earth metals, etc. As it continues to expand, in the field of application of rare earth elements in the application scope will further increase。

"Since 2006, we found Mr.Guo and get products from him. We used magnets under the earth for the gas and water pipe industries. We have met no problem. We have been working in very happy ways. We have many cooperation. Every year, we spent time together and sometimes, we invited him to Korea. He is our younger brother. Strongly recommended!!"

"I had email to Mr. Guo for rare earth magnet requirements. They replied my e-mail promptly, and were very professional. Mr. Guo’s team still continues to deliver rare earth magnets to our agreed specifications with a very high quality standard since 2012. His team is very professional and thorough with its work. Based on my experience, I would highly recommend them."
