发明名称 Shape memory alloy motor as incorpoated into solar tracking mechanism
摘要 The present invention provides a motor driven by shape memory alloys for use in a variety of applications. In the disclosed embodiment, the motor is used to drive a photovoltaic panel so that the panel may remain in appropriate alignment with the sun throughout the day. In such a configuration, the motor assembly relies upon the intrinsic properties of shape memory alloys, in conjunction with a spring assembly, in order to generate sufficient torque in order to rotate the photovoltaic panel. In order to control the orientation of the panel, the system relies upon a sun tracking mechanism which includes an analog sensor circuit, a plurality of phototransistors and a power source. Accordingly, the device is able to rotate the photovoltaic panel in discrete and precise increments as the day progresses.
