cement mill drives wikipedia

Gearless cement mill drives were the first applications of cycloconverters. The mill tube is driven from low-speed wraparound motor with a high number of poles. The input of the three-phase voltage source inverter is the DC bus voltage and control signals, which are six-way bool signals output by a space vector pulse width modulation (SVPWM
