ABSTRACT OF THE DISCLOSURE A laundry appliance includes apparatus for analyzing the eccentricity of a rotatable member with respect to its design rotational axis when subjected to dynamic unbalance forces. An indicator is rotatable with the rotatable member and includes a predetermined detectable pattern. A sensor is juxtaposed to the detec- table pattern and is spaced a predetermined radial dis- tance from the design rotational axis of the rotatable member and indicator. The sensor is cooperable with the detectable pattern for producing an electrical signal corresponding to passage of the detectable pattern during rotary movement of the indicator to generate a stream of electrical signals representing the relative degree of radial displacement of the rotatable member from the design rotational axis. Control apparatus includes a microcontroller in circuit association with the sensor. The microcontroller is operable for receiving and analyzing the stream of electrical signals from the sensor for determining the radial displacement of the rotatable member from the design rotational axis by analyzing changes in the stream of electrical signals.
