Measurement of frictional torque of a directacting valvetrain using a shaft-to-shaft torque transducer to study the effect of Laser Surface Texturing on friction reduction [PDF]
MATEC Web of ConferencesThe study of tribological applications requires measuring various parameters, including RPMs, friction, and wear. The useful information is sometimes not readily available in a measurement and requires further postprocessing to extract that information ...

A high - precision measurement chain for reference purposes
Measurement: Sensors, 2021 Reference transducers not only for high pressure (GPa) but also for high force (MN) and high torque (MN▪m) have been based on foil-type strain gauges for decades, due to their excellent signal-to-noise ratio and established, well-proven technology. Thus,

Aspects Concerning the Torque Ripple Control of the Brushless DC Motor
Advances in Electrical and Computer Engineering, 2013 This paper deals with two advanced numerical structures to control the electromagnetic torque ripple of Brushless Direct Current Motors (BLDCM), indirectly achieved by phase currents control and directly by the Direct Torque Control (DTC) technique. In

Mechanical Evidence of the Orbital Angular Momentum to Energy Ratio of Vortex Beams [PDF]
, 2012 We measure, in a single experiment, both the radiation pressure and the torque due to a wide variety of propagating acoustic vortex beams. The results validate, for the first time directly, the theoretically predicted ratio of the orbital angular ...

Development of a non-contact torque transducer based on the laser speckle contrast method [PDF]
Journal of Sensors and Sensor Systems, 2017 When a torque measurement is required, torque transducers show many drawbacks during their use: the usual limits are the need for contact and the effects on shaft line parameters. A new approach is proposed in this work: a non-contact torque meter for
