Figure 15: V/Hz characteristic curve
for the rating plate of the motor from  Figure 13
a Star connection: 400 V, 50 Hz
b Delta circuit: 230 V, 50 Hz
c Delta connection: 400 V, 87 Hz
The following Tabelle 3 shows the allocation of possible frequency inverters
depending on the mains voltage and the type of circuit.

If using 2 pole motors (p = 1), the high speed of approximately
5,000 rpm must be taken into account (consult the manufac-
turer's specifications).
