Abstract

We have developed torque standard machines based on the lever deadweight system, that is to say the torque generating method using gravity. However, this method is not suitable for expanding low-torque range because weights and moment arms have limitations in size. In this study, we investigated the working principle of torque generating method using electromagnetic force by referring to watt balance experiments for the redefinition of the kilogram.
