Refrigerator temperature control circuit using DC motor

摘要

This research is a kind of DC motor which uses DC motor to adjust the temperature inside the refrigerator,Input AC power, communication rectifier,The output power of the rectifier unit is input and converted into the control unit and of the DC power supply,Sensing the internal temperature of the refrigerator, and the temperature index finger output after converting to the voltage value,The DC power supply of the control unit is input, and the motor driving unit and of the DC motor are driven,The temperature detecting part and the motor driving part input and output signals to the comparison part of the control part,In order to adjust the temperature of refrigerator, DC motor is used, so the efficiency is high,It is characterized by no noise during operation.
