为了使扭矩标准能够应用于各个行业，我们一直在开发基于杠杆自重系统的扭矩标准机，即利用重力产生扭矩的方法。然而，由于配重和力矩臂尺寸的限制，该方法不适合于扩展扭矩范围的低端。在这项研究中，使用电磁力的扭矩产生方法的工作原理进行了研究，参考瓦特平衡实验用于千克的重新定义。将这一原理应用于旋转坐标系，设计并制作了电磁力式扭矩标准机样机。实验证明，SI跟踪扭矩可以通过将电功率转换为机械功率来产生。因此，第一次，SI跟踪扭矩成功地实现了使用的方法，而不是基于重力。
To allow the application of torque standards in various industries, we have been developing torque standard machines based on a lever deadweight system, ie a torque generation method using gravity. However, this method is not suitable for expanding the low end of the torque range, because of the limitations to the sizes of the weights and moment arms. In this study, the working principle of the torque generation method using an electromagnetic force was investigated by referring to watt balance experiments used for the redefinition of the kilogram. Applying this principle to a rotating coordinate system, an electromagnetic force type torque standard machine was designed and prototyped. It was experimentally demonstrated that SI-traceable torque could be generated by converting electrical power to mechanical power. Thus, for the first time, SI-traceable torque was successfully realized using a method other than that based on the force of gravity.
