If a Nord-Lock screw locking device is used, then increase the tightening torque by 10 %!
The motor in series design (conforming to IEC 60034‑17) can be operated with a frequency
converter. Contact customer service if the rated voltage is above 415 V/50 Hz or
480 V/60 Hz. Because of the additional heating caused by harmonics, the rated power of the
motor should be around 10 % more than the power requirement of the mixer. For frequency
converters with a low-harmonic output, it is possible to reduce the 10 % power reserve.
Harmonic waves are reduced by means of output filters. Synchronize the frequency con-
verter and the filter with each other!
The configuration of the frequency converter depends on the rated motor current. Make
sure that the mixer operates across the entire control range without jerking or vibrating
(without vibrations, resonance, oscillation). Otherwise, the mechanical seals may leak or be
damaged. Increased motor noise caused by the harmonics of the power supply is normal.
