Evaluation of synchronous motors on grinding mills IEEE

Both in motor efficiency and in low base speed configurations the synchronous motor has advantages of lower current and higher efficiency. Often used in large Mills in the cement and mining industry, these motors were driven by LCI variable-frequency drives (VFDs) or used with direct start with a clutch system that would synchronize the motor first to overcome low starting torques.
