Applied Research of the Intelligent Temperature-Controlled Speed Adjustable Motor in Radiator Fan

Considering the characteristics of the temperature monitoring under complex working condition, this paper suggests a kind of practical, simple and low-cost control method for the intelligence motor. This method uses AT89S52 and a few periphery components as a control system, and has two control modes. In one mode, the control system takes a real-time monitoring on ambient temperature, and correspondingly changes the revolving speed of motor, providing efficient heat dissipation. And the other Mode 2 provides a way of using remote infrared control to manually achieve the same goal. Through the practical operation, this control system shows its effectiveness and stability. And because of its low cost, it can be used widely in radiator fans.
