Technology Overview
The external-rotor brushless DC (BLDC) motor driver module features high torque with a large rotation radius and flat and thin dimensions specifically for use in low speed applications. With production management, optimization of drive and control technology, and dynamic balance calibration of a matching carrier, the motor is silent and reliable, making it particularly suitable for ceiling fans.
Applications & Benefits
ITRI has integrated motor driver IC suppliers, and printed circuit board (PCB) and motor manufacturers, to provide a comprehensive solution that can be commercialized. It has also collaborated with the largest ceiling fan manufacturer in Taiwan to promote a new business model and to create new product sales channels. A demonstration line with an annual production capacity of 10,000 units has been constructed.
Six hundred new ceiling fan units with external-rotor BLDC motor driver modules have been demonstrated across Taiwan, and 5,000 further units will become available for promotional activities in the near future. This technology and product will be integrated into industries using intelligent automated production lines in Shalun, Tainan, with an annual production capacity of 100,000 units, accelerating their entry into the global market.
