<p>APPARATUS AND METHOD FOR CONTROLLING ELECTROMAGNETIC CLUTCHES AND THE LIKE To energize an electromagnetic clutch or other electromagnetic device having a movable armature, a voltage is applied across the coil of the device to cause an initial current to flow therethrough. A current dip upon initial movement of the armature is detected, and in response, a substantially linearly increasing current is applied to the coil, establishing a controlled movement of the armature.</p> |
