Continuous raw data for verification and analysis
A tool to collect raw data is needed for any profound improvement of electric drives, motors or generators. While a power meter can determine efficiency, it cannot explain that efficiency or help identify approaches that increase efficiency because the data is already compressed.
HBM's eDrive solution continuously stores all relevant data—including currents, voltages, torque, rotational speed and even motor temperature—at high resolution in an integrated system. Additionally, root-mean-square (RMS) values—along with active, apparent and reactive power—are displayed in real time during the measurement, just like with a power meter.
Using powerful mathematical functions and a formula database, the eDrive solution takes measurements and performs analysis directly in the system—instead of requiring separate math packages. This integration saves users time, improves flexibility and lowers the error ratio.
