Designation￿of￿electrical￿machines
The￿electrical￿machine￿designations￿are￿used￿in￿the￿technical￿documentation￿for￿clear￿identification￿of
the￿electrical￿machines.
According￿to￿GS￿90023,￿the￿designation￿of￿the￿electrical￿machine￿used￿in￿the￿I01￿is:
EMP242.130.01.250(300)-A3-X1
In￿frequent￿cases,￿however,￿only￿a￿short￿designation￿is￿used.￿This￿short￿designation￿is￿used￿to￿assign
an￿electrical￿machine￿to￿an￿electrical￿machine￿family.￿For￿instance,￿the￿short￿designation￿EMP242￿is
also￿used.
