Original Kurzfassung:
In a series of experiments the peak current during switch on
of a fast switching valve, which was found to be out of
tolerances with respect to some armature dimensions, was
varied to realize different switch on times. Despite the fact that
the holding current was identical for all cases and the time
between switch on and off was very long, the valve?s switch off
time showed an unexpected dependency on the switch on peak
current value. This paper presents an explanation of this
phenomenon by coarse mathematical models, demonstrating
that the manufacturing error in combination with friction,
skewness, and fluid stiction are responsible for this behavior.
