Linear actuator is a DC motor is the prime mover in a sunlight tracking system. As the name implies, linear or linear actuator moves back and forth. Linear motion is obtained from the results of transmission gears with rotary DC motors. The series of gears on the linear actuator end torque also resulted in a greater linear movement that can lift heavy loads. In general, linear actuator also has a reed relay / switch that serve as a feedback in the form of digital pulses. The digital pulse will become input to the microcontroller to determine the length of a step or linear motion actuator. continue reading…
