ABSTRACT:
Electromagnetic actuators that include a coil and an armature are used in a number of applications. It is desirable to determine the position of the armature with respect to the coil without the use of external sensors. Accordingly, an apparatus is provided that determines the position of the armature with respect to the coil in response to the coil current and voltage.
