ABSTRACT:
Moving iron limited rotation motors, and recorders employing such motors, in which a velocity sensor structure is axially spaced from a drive structure that is shorter than another drive structure of the drive system. In the preferred embodiment shown, a motor having a pair of diametrically opposite drive structures, the sensor is positioned opposite to the end of the longer drive structure and cooperates with it and a coextensive portion of the rotor in defining flux paths. A pair of permanent magnets extend the full length of the drive-sensor structure, supplying flux to both parts.
