Energy-saving elevator --- The demand of EPS and micro-motor NdFeB neodymium iron boron has grown steadily
The power consumption of elevator is huge, which is one of the largest energy consumption equipments in high-rise building. China elevator industry association estimates that the power consumption of elevator every day accounts for about 5-15% of the whole building's energy consumption. At present, the traction machines used in the elevators are mainly permanent magnet synchronous motor and traditional asynchronous motor. Neodymium PM synchronous motor adopts direct drive mode, increasing transmission efficiency significantly, and at the same time significantly reducing about 50% energy consumption than traditional motor. With the implementation of National energy conservation and emissions reduction policy, energy saving elevators which adopting permanent magnetic synchronous motors are the development direction of the future. Our domestic production of elevators is 771,400 units in 2016, increased by 1.5% on year-on-year basis, accounted for more than 90% of the global production.
In 2016, the permeability of domestic energy-saving elevator is approximately 60%, in addition, the amount of neodymium magnets used in every energy-saving elevator is 7 kilos, and hereby domestic NdFeB consumption for energy-saving elevator is expected to be 3240 tons.
(1) considering the real estate investment and new home sales area are greatly increased in 2016, the demand of the elevator is expected to be gradually released within recent two years, assuming that the average annual growth rate of domestic elevator output is 10% in 2017-2018; (2) Assuming that the permeability of energy-saving elevators increase 5% annually. According to the above assumptions, the usage amount of neodymium permanent magnets for the domestic energy saving elevator is expected to be 3861 tons and 4574 tons respectively in year 2017~2018, year-on-year increase 19.17% and 18.46% respectively.
