Motors require the correct phase, voltage, and frequency from an electrical supply system. The system must also have sufficient capacity, or current carrying capability, to start and operate the motor. Motor nameplates include all this information.
Motors operate satisfactorily on voltage that is within 10 percent, or frequency within 5 percent, of the optimal value listed on the motor nameplate. There is a risk of motor damage if the combined total voltage and frequency variation of a power supply exceeds 10 percent.
