ABSTRACT:
An improved synchro including a pair of flats helically-coiled hairsprings (320,330) mounted between a rotatable rotor (100) and relatively fixed stator (200), said hairsprings being electrically conductive for carrying an electrical excitation between a rotor-mounted connector (310) and an external source coupled to terminal blocks (350,360) and for providing a mechanical linkage allowing limited relative rotation between the stator and rotor. The hairsprings are contained within a dielectric or insulating housing assembly (340) which is mounted to or carried on the stator and each is coupled to one of a pair of spaced electrical contacts (312,314) on the rotor-mounted connector. As such, the system provides an electrical interconnection between the contacts (312,314) and the terminal blocks (350,360) for rotor energization, while maintaining a rotatable mechanical connection between the stator (200) and rotor (100).
