This year the amount of brushless DC motor is not many, the next three to five years the application of the brushless DC motor blowout. Although the importance of air duct fan motor air conditioning companies are increasingly recognized, but most of the domestic air conditioner manufacturers are not use new brushless DC motor technology in aspects of the wind tunnel fan motor. A major motor of domestic R & D personnel analysis to the "China Electronics News" reporters that, of which there are several reasons: First, the changes in the industry need a process. Air conditioning manufacturers will eventually use the DC brushless motor." He said, "But the transformation, research, development and production of it need a process."

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.

Although the compressor and heat exchanger is confirmed, the general level of energy-saving air-conditioning has been confirmed, but the motor like we usually wind tunnel called "the last straw breaks the camel." During the coming year, brushless DC motor in the fixed-frequency air-conditioning on the application will be "eyes of the beholder, the wise see wisdom", but in later years, Brushless DC motors' applications will blowout. This will bring new opportunities for semiconductor companies. A dedicated motor controls chip in the past mainly concentrated in the hands of Japanese suppliers, and after the controller using MCU (MCU) or DSP (digital signal processor), there will be more semiconductor companies benefit from it.

Because the controller can be placed in an external motor controllers interface with the machine as a whole to better connect the air conditioning companies designed their products faster, and such being this case, the overall costs can be reduced. Thus, from the air conditioning business point of view, brushless motor manufactures are more willing to choose MCU to program their own development.

Dedicated ago, motor controls in the past mostly focused on Japanese chip suppliers such as Hitachi, Sanyo, Sanken and Roma and so on. It is reported that the market mainly produce electronic and Renesas MCU-based STMicroelectronics. Semiconductor industry provide 8-bit products for low-end,  to provide low-cost 16-bit or 32-bit products for sine and other more complex vector calculations.
