Abstract
A brushless rotary signal transducer having a novel configuration to provide A.C. output voltages in stator windings proportional to the speed of rotation of a rotor and the voltage of a D.C. excitation signal applied to an excitation winding is provided. The excitation winding and stator are disposed within a magnetic permeable housing substantially axially aligned about the axis of the housing. A rotor formed of magnetic permeable material is rotatably mounted on the housing axis, at least the portion thereof in radial registration with the stator being magnetically asymmetrically distributed about said axis. A rotating closed flux path is defined by the rotor, stator and housing.
