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.

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)

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 ...

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 ...

Electromagnetic Torque and Its Ripples in a Unipolar Brushless Torque Motor with Permanent Magnets
Russian Electrical Engineering, 2021A physical and mathematical model is given, along with a computational and analytical description of physical processes in the electric motor and their relationship with the design of its equivalent electromagnetic circuit. The sources are determined and the relationships are investigated when the electromagnetic torque ripples occur.

Spin-Torque Oscillator in an Electromagnet Package
IEEE Transactions on Magnetics, 2012Spin-torque oscillators (STO) hold promise for multi-octave frequency operation at very high frequencies and modulation speeds. STO operation is typically demonstrated using large electromagnets and probe stations, and has so far not been packaged with a portable form factor. For STOs to be utilized in real applications, a smaller packaging solution is
