Vector controller for a permanent magnet synchronous motor, inverter module, and permanent magnet synchronous motor constant display system
A vector controller for a permanent magnet synchronous motor uses current command values and detected currents of the d-axis and q-axis, a calculated frequency, and motor constant settings to control the output voltage of a power converter; the motor constants are identified by use of active or reac...

| Zusammenfassung: | A vector controller for a permanent magnet synchronous motor uses current command values and detected currents of the d-axis and q-axis, a calculated frequency, and motor constant settings to control the output voltage of a power converter; the motor constants are identified by use of active or reactive power obtained from the output voltage and detected current of the power converter, the calculated frequency, and the detected current immediately before or during an actual operation. |
