Magnetostrictive Type Torque Sensor
SAE Technical Paper Series, 1991<div class="htmlview paragraph">A highly sensitive, non-contact torque sensor was developed using amorphous magnetic alloy. A thin strip of amorphous magnetic alloy was bonded onto the surface of the shaft, formed into a chevron shape, then the torque applied to the shaft was detected from the difference in the inductance of the detection coil ...

Torque sensor using perpendicularly magnetizing coils
IEEE Transactions on Magnetics, 1991A quick response and robust torque sensor is presented for a carbon-steel shaft on which a pair of magnetostrictive layers were formed and a pair of twin coils were set. A current flows through a twin coil generating a magnetic field perpendicularly applied to the magnetostrictive layer plane, which simultaneously magnetizes the steel shaft in a radial

Novel sensor design for torque magnetometry
Review of Scientific Instruments, 2007Torque magnetometry is a powerful method to determine a sample’s magnetic properties. In a torque magnetometer, the sample under interest is mounted on a suitable sensor, the core part of the instrument. Piezoresistive atomic force microscope tips are proven to be very useful torque sensors and have already been optimized for the specific needs of ...

Dynamic force/torque sensors: theory and experiments
1997 8th International Conference on Advanced Robotics. Proceedings. ICAR'97, 2002Although present-day force/torque (F/T) sensors are mostly designed and used as if they were quasi-static devices, if significant compliance and/or stringent requirements on measurements bandwidth are in order, a dynamic analysis of such sensors is necessary.

High Performance Milling Torque Sensor
Manufacturing Science and Engineering: Volume 2 — Non-Traditional Design and Layered Manufacturing; Rolling Technology; Intelligent Machine Tool Systems; Measurement and Inspection of Products and Processes; Non-Traditional Manufacturing Processes of the 1990s, 1994Abstract Machine tool supervision and control algorithms require reliable and effective sensor signals to operate properly. In effort to satisfy this need, a high stiffness, wide bandwidth torque sensor for use in milling has been developed which directly measures the torque applied to a milling cutter during operation.

Optical Torque Sensor Development
2010The purpose of this study is to develop a contactless torque sensor in the mNm range. The applied optical method is based on the birefringe effect of photoelastic materials. The novelty of the modified reflective photoelastic method is the application of a photoelastic tube as a coupling and measuring element between shafts.

Magnetostrictive Torque Sensors and Materials
IEEE Translation Journal on Magnetics in Japan, 1992Shaft torque sensors based on the magnetostriction effect and magnetostrictive materials used in such sensors are reviewed. Torque sensors employing amorphous ribbons in a chevron pattern and with solenoidal pickup coils have been developed for highly sensitive torque measurements in an intermediate dynamic range.

Variable magnetic circuit torque sensor
Journal of Applied Physics, 1991This paper presents an original torque sensor structure using the properties of magnetic circuits, including permanent magnets. The torque is measured through the torsion of the transmitting shaft. The torsion is proportional to the torque. Considering two points of the shaft on the same line in absence of torque, the information is given by the ...

Torque control of electric motors without using torque sensor
2007 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2007Accurate torque control of a brushless motor requires the motor's torque characteristics, which can be captured by a periodic function in motor angle. This paper presents a direct adaptive controller for torque control of brushless motors, which estimates the Fourier coefficients of the periodic function based on the measurements of motor phase voltage
