| Abstract: | This paper introduces the hardware composition and the software development of a data acquisition system used in the electric machine test based on LabVIEW.A method which can realize high-speed continuous data acquisitionand saving data in LabVIEW, and a new harmonics analysis method which can search out the first-harmonic frequency are presented. Then factors that cause the relative phase-angle error in the operate mode of circulating sampling is analyzed, and an operate mode of group sampling is presented to reduce the error. Eventually some test data are given to verify the feasibility and correctness. |
