Motor seng range
Rated point 120 Hz
Only possible with Lenze MF motors.
The rated motor torque is available up to 120 Hz.
Compared to the 50-Hz operaon, the seng range increases by 2.5 mes.
Thus, a smaller motor can be selected at the same rated power.

Rated point 87 Hz
The rated motor torque is available up to 87 Hz.
Compared to the 50-Hz operaon, the seng range increases by 1.74 mes.
For this purpose, a motor with 230/400 V in star connecon is driven by a 400-V inverter.
The inverter must be dimensioned for a rated motor current of 230 V.
