This paper presents a novel dynamic torque generator based on the principle of the Kibble balance. The generator is developed to dynamically calibrate torque-measuring devices (TMDs) for the measurement of dynamic torque. Unlike conventional gravity-based deadweight torque standards, this method uses electromagnetic force to generate a dynamic torque traceable to the International System of Units (SI). Dynamic torque is generated by dynamically changing the electric current supplied to the coil. Consequently, dynamic torque is generated up to 100 Hz. Furthermore, a system is developed to simultaneously measure the electric current and output of a TMD to verify the evaluation method of the dynamic characteristics of a TMD.

“…This study presents the development of a novel dynamic torque generation machine (DTGM) based on the principle of a Kibble balance [28]. The National Metrology Institute of Japan (NMIJ) first developed a static torque generation machine based on this principle, which generated a low torque (lower than approximately 10 mN m) [29,30].…”

“…Studies have been conducted in some countries to measure dynamic torque accurately [1], [2]. NMIJ has been advancing research on the precise measurement of dynamic torque by using electromagnetic force based on the principle of Kibble balance [3]. This method measures dynamic torque by comparing the time-varying electric current and the torque generated thereby.…”

This study investigated the uncertainty evaluation procedure in the dynamic torque realised by a dynamic torque generating machine (DTGM) based on an electromagnetic force under development at NMIJ. The dynamic torque can be generated by changing the applied current. The generated torque can be traceable to the International System of Units (SI) by referring to the national standards of voltage, current, angle, and frequency.
