Abstract
This paper describes a recent case study of replacing an eddy-current clutc h with a modern medium-voltage adjustable-speed drive (ASD) for a 2250-hp e xtruder application. It covers key issues, justification, factory and held measurements of torque-speed profile from 0.5 to 60 Hz, as well power quali ty analysis. The paper reviews manufacturers' capability to build medium-vo ltage ASDs that produce very high and stable torque at very low speed.
