Air condition controller chip
Domestic air-conditioning R & D analysts said. Although the gross profit margin of DC brushless motor is higher than the traditional brush motor, but in a sense, the motor manufacturers are working for semiconductor companies. New motor technology gross profit margin is not as high as the motor controllers.
Moreover, in the air conditioning industry, the demand for the controller chip is also changing, Main controllers are dedicated chip and MCU / DSP two kinds, In the early days, Motor manufacturers have integrated controllers in the motor, they generally select the specific controller. Now, some air conditioning companies want to put the motor outside the controller, especially for fixed-frequency air-conditioning, such trends are becoming apparent.
