Electric motors constructed specifically to ensure reliable operation when fed from variable speed frequency drives prevent the destructive phenomenon called “corona” from occurring. This damage exists to a greater degree when operating motors from pulse-width modulated inverters. The Simple Truth About Motor/Drive Compatibility details findings and solutions.
