| Abstract: | This paper introduces an intelligent protector for three phase motors which has the PICMCU as the core.It uses the PICMCU with the A/D change over module which helps to overcome the instant electric current dynamic changing period succesfully.The protector samples the working electric current of the motor correctly when the current is steady,and it can protect the motor when the motor has the problems of motor missing,overload electric,lack of electric or lack of voltage.This kind of protector not only has the simple circuit but also is convenient. |
