Application of Virtual Instrument LabVIEW in Variable Frequency and Speed Motor System

Abstract

The working process of the virtual instrument system: first the signal input signal system acquired by a sensor conditioning circuit, the signal conditioning circuit for amplifying, filtering, and then through the data acquisition card into the memory, then carries on the data analysis and processing of the collected data. This paper uses virtual instrument environment LabVIEW to the transmission, processing and graphic signal data acquisition system for motor experiment. The method proposed in this paper can analysis electrical parameters in different circumstances of variable frequency motor performance.
