One Real-Time Monitoring and Fault Diagnosis System of Motor Based on DSP

According to meet the requirements for running reliably and highly efficiency of 3-phase large asynchronous motors,a system of real-time working condition monitoring and fault diagnosis of motors based on DSP was designed.The hardware part of the system was introduced and the whole function and implementation procedure was illustrated.The modular structure is adopted,running states monitoring,data recording and faults diagnosis were integrated in the system,which can realize the function of real-time monitoring and fault diagnosis.The results showed that the system was running stably,the data recording was accurate and diagnosis results were highly reliable.
