Operaon on a frequency inverter
Large seng ranges and opmum operaon with rated torque. These are the strengths of the
MF motor on the frequency inverter. Compared to the 50-Hz operaon, the seng range
increases by 250 %. It is quite simply not possible for a drive to be operated any more
eciently in a machine.

Torque reducon at low motor frequencies
At low motor frequencies (usually < 20 Hz) and with an integral fan, the motor is not cooled
suciently at the rated torque. The motor can be operated from 5 Hz by reducing the torque
accordingly.
Constant cooling takes place over the enre speed range in motors with a blower. This means
that they can be used with their rated torque from 5 Hz.
