Abstract:
A driving mechanism comprises a fixed housing, a movable housing on which an object to be driven is mounted and a driving motor which is operative to drive the movable housing to move linearly as well as to rotate relative to the fixed housing. An inductance-type encoder determines both linear and rotary displacement of the movable housing relative to the fixed housing, whereby to provide closed-loop control of the position of the object in both linear and rotary directions.
