Appendix A: Motor Rotor Inertia, Iec - ABB ACS880 Firmware Manual

Appendix A: Motor rotor
inertia, IEC
The table given below is an example of common inverter duty AC motor rotor inertia.
The data is from the ABB cast iron totally enclosed squirrel cage motors catalog.
The electrical ratings are based on 400 V AC 50 Hz sinusoidal input.
