ABSTRACT:
A synchronous transmission device of the vernier resolver type, in which a variable reluctance is produced by the rotation of an unwound magnetic rotor, wherein unwanted inductive and capacitive coupling effects between windings, resulting in parasitic signals appearing in the secondaries, are suppressed by application of compensating signals picked-off through the coupling of each secondary with a compensating winding, the supply to which is picked-off from the excitation signals applied to the primary, and adjusted by a divider bridge.
