8.6 Vibration suppression (hysteresis)
Low rotation speeds and higher relative vibrations
between the rotor and the stator can cause disturbance
signals that reverse the direction of rotation. Electronic
suppression (hysteresis) to eliminate these disturbances
is connected at the factory. Disturbances caused by the
radial stator vibration amplitude and by the torsional
vibration of the rotor are suppressed.
