2-AXIS SOLAR TRACKER SYSTEM WITH BLDC MOTOR AND HALL SENSOR FEEDBACK BASED ON TIME

摘要

The present invention relates to a photovoltaic tracking system for photovoltaic power generation, and to improve the efficiency of photovoltaic power generation, by simultaneously adjusting the altitude angle in the north-south direction and the azimuth in the east-west direction by using a BLDC motor and a hall sensor, the present time The present invention relates to a two-axis solar tracking system using BLDC motor driving and hall sensor position feedback based on the current time, which tracks sunlight in real time. According to the present invention, a two-axis solar tracking system of BLDC motor driving and hall sensor position feedback based on the current time includes: brushless DC motors 320 and 420 and two solar panels 100. A driving unit (300, 400) for turning in the axial direction; and a control panel (200) for calculating the position of the sun according to the current time and controlling the driving units (300, 400) according to the calculated position of the sun; and And a tracker mechanism 500 that connects the driving units 300 and 400 to the solar panel 100 to pivot the solar panel 100 in two axial directions, and the operation panel 200 includes the BLDC motor. The rotational positions of the 320 and 420 are fed back through a hall sensor.
