Apparatus for detecting a vibratory movement of a laundry drum

摘要

An apparatus detects a vibratory movement of the rotary shaft of an internal unit, which is suspended such that it can vibrate, of a washing machine having a laundry drum which is driven by an electric motor. The apparatus has a sensor part and a measured-value detector which is connected to the rotary shaft and provides a measured variable which varies periodically with the rotational speed of the rotary shaft and periodically with the vibratory movement in at least one direction parallel to the axis of rotation or in at least one radial direction.
