Revolutionary Drive Controller for Gearless Mills ABB Group
Ringmotor of the Gearless Mill Drive (GMD) System. CYCLOCONVERTER Principle The Cycloconverter is a frequency changer which converts a poly-phase voltage with the frequency f1 into a single or poly-phase voltage with a different, lower frequency f2. On Gearless Mill Drives (GMD), the operational output frequency varies from 0.3 Hz up to about 6 Hz.AC TO AC (CYCLOCONVERTER) SPIRO THE TECH GURU,The Cycloconverter has been traditionally used only in very high power drives, usually above one megawatt, where no other type of drive can be used. Examples are cement tube mill drives above 5 MW, the 13 MW German-Dutch wind tunnel fan drive, reversible rolling mill drives and ship propulsion drives.
