LI Runchun · Industrial Instrumentation & Automation · 2010
A communication-capable intelligent motor protector based on fieldbus is designed on the basis of single chip dsPIC30F6012.Finally realizes protection for motor when occuring over loading three phase imbalance or lose phase,and real-time monitoring of the motor by connecting upper monitor.And the relevant software design,hardware circuit and the realization of communication based on DeviceNet are introduced phase.The showpiece is proved to be reliable.It is good in real time performance and easy to realize.
