9.9 Motor data - characteristic curves
9.9.1 50Hz characteristic curve
(Æ Adjustment range 01:10:00)
a) 115V / 230V frequency inverter
For 50Hz operation, the motor can be used at the
rated torque up to its rating point of 50Hz/230V.
In spite of this, operation above 50Hz is possible,
however the output torque reduces in a non-linear
manner (see following diagram). Above the rating
point the motor enters its field reduction range, as
with an increase of frequency above 50Hz, the
voltage can not be increased above 230V. Due to
the mains voltage, only max. 230V are available.
Up to a power of 4 kW, the following data refer to
a 230/400V motor winding.
