Abstract

This paper describes the next generation prototype of the Electronic NIST Torque Realizer (ENTR) project. The first prototype version (ENTR-v1) has been able to realize low-range torques (on the order of 1×10-3 Nm) to uncertainties of less than 1000 parts in 1×106. The second generation prototype (ENTR-v2) has been designed and constructed specifically with the goal of realizing at least 1Nm of torque utilizing a DC direct-drive design and traceability to quantum standards without the need for physical mass and length standard artifacts. The paper will describe some of the design decisions of ENTR-v2 in order to reach this higher range of operation, and we aim to present results of torque realization verification with a full uncertainty budget within the coming months.
