ABSTRACT:
A rotary transformer such as for use in a torque-meter structure arranged to have reduced cross talk between the excitation and signal transformer portions, and to have improved durability. In the illustrated embodiment, the air gaps of the transformer section are disposed outboard relative to each other, with the U-shaped cores opening away from each other toward outboard support bearings to provide a circuitous flux path and thereby reduce cross talk between the transformer sections. A two-piece housing structure minimizes dimensional errors in manufacture. The rotor support has a large axial mounting contact for improved accuracy and stability as a result of the short length of the core housing the improved structural arrangement.
