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.
The Yokogawa DL950 ScopeCorder captures and analyzes a wide variety of electrical, physical sensor signals, and serial buses. It offers a unique combination of high sampling rates, for a detailed view and long recording times to monitor trends over time.
Yokogawa, the world's largest manufacturer of energy and power analyzers and meters, provides a broad choice of digital power analyzers to satisfy all requirements.
