Design Of Intelligent Testing System Of
Three-Phase Induction Motor
Abstract: Three-phase induction machines, one kind of important electromechanical product, are widely used in various fields, from industry, agriculture to household applications. But the traditional manual method of testing electrical machinery has a lot of shortcomings. For example, the measure time is often out of step, the human lilctor is of great impact, the efficiency is poor and so on. SCM systems are adopted in data collection and processing of this system. It uses SCM system as core and makes keyboard input and data display as assistance measures the voltage and current of three-phase induction motor. By building mathematics model according to the relations between electric parameters and voltage and current, the measurement of electric parameters such as real power, reactive power, apparent power and power factor, etc. can be carried out. This paper introduces the achievement of hard-ware and software of this system, and proves the practicality of it by experiment.
