Calculation of rotating coordinate system dq-axis parameters of Permanent Magnet Synchronous Motor (PMSM) using Clarke & Park Transformation with the Precision Power Analyzer and the Waveform Measuring Instrument’s High-speed Math Function
The Yokogawa WT5000 Precision Power Analyzer and DL950 ScopeCorder have a function to measure electrical angles. This function can be used to calculate the dq-axis parameters of PMSMs.
This white paper describe how to calculate dq-axis parameters along with actual measurement results using the WT5000 and DL950.
