100Hz characteristic curve (only 400V devices)
( Adjustment range 1:20)
For a large speed adjustment range up to a ratio of 1:20
an operating point of 100Hz/400V may be selected. For
this, special motor data is necessary (see below), which
deviates from the normal 50Hz data. Care must be
taken that a constant torque is produced over the entire
adjustment range, however this is smaller than the rated
torque for 50Hz operation.
In addition to the large speed adjustment range, a
further benefit is the better temperature characteristic of
the motor. In the low output speed range an external
fan is not strictly necessary.
NOTE: The following motor data applies for
standard motors with 230/400V windings.
