8.8.2 87 Hz characteristic curve (only 400V devices)
( Variation 01:17)
The 87 Hz -
characteristic represents an
extension of the speed adjustment range with
a constant motor nominal torque. The
following points must be met for realisation:
•
Motor delta connection with a motor
winding for 230/400 V
•
Frequency inverter with an operating
voltage 3~400 V
•
Output current of frequency inverter must
be greater than the delta current of the
motor used (ref. value  frequency inverter
power ≥ √3 motor power)

Figure 39: 87 Hz characteristic curve
In this configuration, the motor used has a rated operating point at 230 V/50 Hz and an extended
operating point at 400 V/ 87 Hz. This increases the power of the drive by a factor of √3 The nominal
torque of the motor remains constant up to a frequency of 87 Hz. Operation of a 230 V winding with
400 V is totally uncritical as the insulation is designed for test voltages of > 1000 V.
