8.8.2 87 Hz characteristic curve (only 400 V devices)
(

Variation 1:17 AM)
The 87 Hz characteristic represents an
extension of the speed adjustment range with
a constant rated motor torque. The following
points must be met for realization:
• Motor delta connection with a motor
winding for 230/400 V
• Variable Frequency Drive with an operating
voltage 3~400 V
• Output current of variable frequency drive
must be greater than the delta current of
the motor used (ref. value

variable
frequency drive power ≥ √3 motor power)

Characteristic 87 Hz (4-pole motor)
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.
