本文介绍了一种无线传感器供电的应用。我们利用空气运动来驱动一个微型风力涡轮机。其目的是在室内用于加热、通风和空调的空气管道中使用该器械。我们为气流涡轮机使用了市售的现成组件。一个低速，三相，无刷直流调速器用于发电机。由六个二极管构成的三相桥用于将来自电机的AC电流转换为低功率传感器所需的DC电流。我们用了一个四英寸的风扇叶片作为涡轮机叶片。我们使用阻力负载对气流涡轮机进行了一组测试，以证明其能量转换潜力。我们还展示了它可以持续为无线传感器供电。
This paper describes an application for powering wireless sensors. We use air motion to drive a miniature wind turbine. The intent is to use the device indoors, in air ducts used for heating, ventilating, and air-conditioning. We used commercially available off the shelf components for the airflow turbine. A low-speed, three-phase, brushless DC servomotor was used for the generator. A three-phase bridge constructed from six diodes was used to convert the AC current from the motor to DC current required by low-power sensors. We used a four-inch fan blade for the turbine blade. We conducted a set of tests on the airflow turbine using resistive loads to demonstrate its energy conversion potential. We also showed that it could power a wireless sensor continually.
