siemens/mining SIMINE Gearless Mill Drives

a given issue for a Gearless Drive system. A harmonic study individually determines whether or not the particu-lar plant configuration and network need harmonic filter-ing. As the Drive concept is a 12-pulse system, only the 11th and the 12th harmonics with their related sidebands have to be looked at. Harmonics with higher harmonic order exist, but their magnitude is negligible. The starting ...
