Abstract

Apparatus in accordance with embodiments of the present invention provide torque realization via electrical measurements traceable to the revised International Standard of Units (SI). Torque can be realized via a conversion of linear mechanism of a Kibble balance to a rotational mechanism. Embodiments of the present invention relates to an electronic torque realization apparatus including a rotor for holding permanent magnets and an encoder scale ring and for coupling to a torque device, a stator for characterizing physical aspects of a torque tool and for generating the torque on rotor in conjunction with the permanent magnets, a base plate for mounting a first end of rotor and stator, a cantilever for supporting a second end of rotor and for maintaining axial alignment, a bearing assembly for supporting the motion of rotor, and encoder for recording the angular position of rotor.
