we have require a Motor (1500kW, 6.6kV, 50Hz) which shall operate at 1500rpm during 30min and after it shall run on 500rpm during 15min. The same cycle shall be repetitive during the whole working days. Which method is best and economic to achieve such type of task. VFD, VVFD, Pole changing motor etc.
