We have a centrifugal pump that is powered by a 675kW DC motor (two speed) which we want to replace with AC motor and AC-VSD control.
Is it as simple as requiring a 675kW AC motor ? Are there other factors , derating factors to consider in relation to the starting characteristics of AC versus DC motors?
Thanks for any feedback
