3.2.13. Rated data according to rated voltage variation
The nominal characteristics and especially the rated speed, maximal speed, rated
power, rated torque, depend on the nominal voltage supplying the motor considered
as the rated voltage. The rated data mentioned in the data sheet are given for each
association of motor and drive. Therefore, if the supply voltage changes, the rated
values will also change. As long as the variation of the rated voltage remains limited,
for instance

10% of the nominal value, it is possible to correctly evaluate the new
rated values as illustrated below.
