3.6 Fluctuations in the power voltage and frequency
Standard: Rotation electricity machine general rules
IEC60034-1:2004
To the voltage change and frequency change in
Domain A, in main rated values, it operates
continuously, and can be used practically convenient,
and to the voltage change and frequency change in
Domain B, it shall operate with main rated values
and shall be used practically convenient.
However, operation with "it is convenient and safe is
maintained on "practical use, it means not resulting
in the grade which shortens a life remarkably, and
the characteristic, a temperature rise, etc. do not
apply correspondingly in the state of rating. Moreover,
main rating shows rated torque (N
