Performance CharacteristicsPerformance CharacteristicsPerformance characteristics of motors change when they are operated at high or low voltages at rated frequency. Table 9-5 shows the characteristic and the change when operated 10 percent above rated voltage and 10 percent below rated voltage. Winding failures resulting from extreme voltage variations are identical to those of overloads because the input current is uniformly excessive.
