Nano Letters, 2012
The well-established single-molecule force-spectroscopy techniques have recently been complemented by methods that can measure torque and twist directly, notably magnetic torque tweezers and the optical torque wrench. A limitation of the current torque measurement schemes is the intrinsic coupling between the force and torque degrees of freedom.

Anisotropy component of electromagnetic force and torque
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2010 The paper deals with the problem of surface-integral representation of electromagnetic force/torque for magnetically anisotropic region. It is pointed out that in some anisotropic regions a component of electromagnetic force/torque appears the so-called anisotropy component.

Torque Control Method of an Electromagnetic Spherical Motor Using Torque Map
IEEE/ASME Transactions on Mechatronics, 2016This paper describes a new method for driving electromagnetic type spherical motors that has arranged permanent magnets on a rotor and arranged electromagnets on a stator. The most significant feature of this method is, in principle, applicable to any permanent magnets arrangement and electromagnets arrangement, and it can generate torque to any ...

Calibration of a torque measuring device using an electromagnetic force torque standard machine
Measurement: Journal of the International Measurement Confederation, 2019Abstract To realize a microtorque standard, we have been investigating the principle of torque generation with an electromagnetic force by referring to the Kibble balance method used for the redefinition of the kilogram in the International System of Units (SI). In a previous study, we developed an electromagnetic force torque standard machine (EMTSM)

Electromagnetic Torque Analysis for All-Harmonic-Torque Permanent Magnet Synchronous Motor
IEEE Transactions on Magnetics, 2018This paper proposed a new type of permanent magnet synchronous motor (PMSM) called all-harmonic-torque PMSM (AHT-PMSM) to enhance the electromagnetic torque by using all harmonics of the magnetomotive force. The stator windings structure, drive converter configurations, and control model of the AHT-PMSM are illustrated.

Physical Review B, 2022
Structured light mechanically interacts with matter via optical forces and torques. Optical torque is traditionally calculated via the flux of total angular momentum (AM) into a volume enclosing an object. In the work published in [Phys. Rev. A 92, 043843 (2015)1050-294710.1103/PhysRevA.92.043843], a powerful method was suggested to calculate the ...
