AC variable-frequency drives are the beneficiary of manyrecent electronic advances. In these drives, the speed of theAC motor is proportional to the output frequency of thecontroller, with voltage varied in proportion. The develop-ment of power transistors and logic devices has enabled thesedrives to produce variable-frequency power compatible withvirtually all AC motors up to 40 hp (30 kW).

Drive selection for rolling mills - Russula

20.05.2010· Long product rolling mills are one of the most demanding applications for motor drives. The rolling process consists of passing a hot steel billet through a "rolling mill", also called a "rolling train". The modern rolling train consists of multiple rolling stands arranged in an in-line configuration. Each rolling stand consists of a top and a bottom roll, driven through a gearbox by an electric motor. The
