Abstract
An exemplary device for determining a position of a component moved by operation of a motor includes a rotating member that rotates responsive to operation of the motor. At least one accelerometer is supported on the rotating member. The accelerometer provides at least one of an indication of a tangential force that is tangential to a direction of rotation of the rotating member and a radial force that is perpendicular to the tangential force. A controller determines the position of the component based upon the force indication from the accelerometer.
