Designing On the Computer colleting And Processing System for cycloconverter-fed synchronism Motor
[Abstract] With the development of electrical machinery, technology of cycloconverter is used winder and winder. So studying the system of auto-collecting for cycloconverter-fed synchronism motor has an important meaning.
The focal point of this paper is the data colleting of the output voltage and current of the cycloconverter-fed synchronism motor, we used the LEM current-sensor of Beijing LEM Company. In order to solve the problems of distortion in wave form, we used the data colleting board HY-8021. This system solves a series of problems like measuring and testing of moment frequent conversion through module structure of its hardware and software. The paper also analyzes the appropriate eliminating measure.
Besides, we also introduced the characteristics of the cycloconverter-fed synchronism motor, the situation of the cycloconverter and the circuit and also the principle of the current-sensor, the paper introduced the problem of resist interference in the end.
