Rare-earth Permanent Magnet NdFeB Application Development to Expand

Rare-earth Permanent Magnet NdFeB Application Development to Expand with the development of alternative permanent magnet synchronous motor

Rare-earth Permanent Magnet NdFeB Application According to rare earth metal net news, at present, China is the world’s largest elevator producer and consumer, exporter. According to estimates by the China Elevator Association, China’s average daily power consumption of each elevator about 40kWh, about 5% of the building energy consumption.

Elevator power consumption is huge, is one of the largest high-rise building energy consumption equipment. Due to the application of rare earth permanent magnet NdFeB, elevator motor has a small size, low loss, high efficiency, low noise, etc., has developed into a new traction machine mainstream models, and occupy the mainstream market position. Installed permanent magnet synchronous motor technology, machine room elevator, elevator energy consumption in the entire building is expected to be controlled at about 3%, the average savings of 3000-5000 yuan per year per elevator electricity.

Energy-saving elevator market demand in the future include four major areas, one is the new demand (including the construction of rail transit), the second is the replacement of the old lift, the third is the old energy-saving elevators, four more than four buildings must be equipped with elevators Coercive measures. Public data show that, as of the end of 2015, the use of life more than 15 years, about 8-10 million elevators. The number of lifts that will run for more than 15 years will increase dramatically, reaching 400,000 by 2020.

As the synchronous motor of the elevator driving machine part, the energy consumption accounts for more than 80% of the power consumption of the elevator. Therefore, the application of energy saving and environmental protection permanent magnet synchronous motor is of special significance. With the advancement of energy saving and environmental protection, and the continuous improvement of permanent magnet synchronous motor technology, permanent magnet synchronous gearless traction machine products will be more widely used, eventually 100% replace the traditional traction machine. Rare-earth Permanent Magnet NdFeB Application / Rare-earth permanent magnet NdFeB is to achieve energy-saving environmental protection of the permanent magnet motor important material, its application will be replaced with the development of permanent magnet synchronous motor development of the expansion.
