Abstract:
A method of disengaging an axle disconnect system including providing an actuator having a coil (214) at least partially surrounded by a housing (220), an armature (216) located within the housing and the coil, where the armature is capable of actuating between a first and second position, and at least one of the housing and the armature is part of a magnetic circuit. Applying a current to the coil and actuating the armature from the first position to the second position. Developing an uninterrupted magnetic flux through the magnetic circuit and stopping application of the current to the coil. Permitting the magnetic flux through the magnetic circuit to continue in its uninterrupted state and maintain the armature in the second position. Applying an alternating current, having decreasing amplitude over time, to the coil to dissipate the magnetic flux through the magnetic circuit.
