Abstract
The paper describes the hardware configuration design of an electronic thermaloverload and thermallock protector with PIC16F877 single chip. This design uses a method for microcontroller-based relay of motor thermaloverload and thermallock. This intelligent protector has a high performance-cost ration. Its reliability is improved. The paper gives mathematical model of the protection, discrete algorithm and realizing method based on microcontroller. The protector can make precise judgement to motor thermaloverload and have higher reliability and repetition. The precisions of its action value and action time can meet the need of general engineering application. It also can realize serial communication to the superior computer by RS-232C interface chip.
