ABSTRACT:
A motion and position sensor includes a stationary member having active conductors that carry energizing power and sensing conductors that are electromagnetically coupled by a movable member to generate signals in the sensing conductors that are representative of the position of the movable member. The movable member is contactless and therefore requires no electrical connection to any other component. Thus, frictional reactance torque and electromagnetically generated torque are reduced to a minimum.
