碩士 === 國立高雄應用科技大學 === 電子工程系碩士班 === 102 === In this thesis, a wireless control technology of rotational speed of a fan is proposed. Using driver IC, related electronic circuit, and Bluetooth chip, a control and wireless transmission module of a single phase DC brushless fan is established. Through our application software, the rotational speed of fan can be controlled by an Android smart phone. The electricity charge of AC fan was compared with DC brushless fan. At 3000 RPM of rotational speed, the power consumption of AC fan is about 20 W and its electricity charge is about NT 44 dollars per month. The power consumption of DC brushless fan is about 2.4 W and its electricity charge is about NT 5 dollars per month. The DC brushless fan can save energy significantly.
