New policy will make great effect for Chinese motor producers
This year in March, the State General Administration of Quality Supervision, Inspection and Quarantine, the Standardization Administration issued a "room air conditioners limit value of energy efficiency and energy efficiency rating" mandatory national standards. New standards require that starting from June 1, 3, 4, 5-class on the market today fixed-frequency air-conditioning will be banning the production and sales
For new energy efficiency standards, some domestic air-conditioning R & D personnel of large enterprises said frankly that have some difficulties to achieving higher energy efficiency standards at a reasonable cost. However, some Japanese enterprises said that they felt to reach a new level of energy efficiency is not difficult, because the energy efficiency of their existing products have already reached the current level of 2 or above, An industry source said the Japanese-funded enterprises in air conditioning energy saving technology has been at the front. At present, the Japanese air conditioning compressor and electrical motor manufacturer account for a large proportion of the factory, although in recent years, the output of these companies has grown rapidly in China, but in fact mostly of them used Japanese factory equipments. And Japanese factory equipment were updated all of these years, they established brushless DC motor as the representative of the new technology workshop, enterprises have not yet mastered the advanced core technology, so it is hard for Chinese brushless motor manufacturers to develop and produce brushless motor.
