Interlayer magnetic coupling: The torque method

Physical Review B, 1996
We present ab initio calculations of the interlayer exchange coupling between two, in general noncollinearly aligned magnetic slabs embedded in a nonmagnetic spacer. Based on a surface Green’s function formalism, two equivalent but formally and physically different approaches are examined and discussed. For the Co/Cu/ Co~001!

Femoral Transverse Torque: An Assessment Method

Journal of Orthopaedic & Sports Physical Therapy, 1986
This study compared external and internal femoral torques of asymptomatic male and female subjects. Peak torque values were recorded using the Cybex(R) II isokinetic dynamometer utilizing a prone testing position with the hip in neutral. Males produced significantly higher raw peak torques than females in both external and internal rotation (p < 0.003).

Instantaneous Torque Control of SRM with a Logical Torque Sharing Method

2007 IEEE Power Electronics Specialists Conference, 2007
A novel non-linear logical torque sharing function (TSF) is presented. To improve efficiency and to reduce torque ripple in commutation region, only a phase torque under commutation is regulated to produce a uniform torque. And the torque developed by the other phase remains with the previous state under a current limit of the motor and drive.

Cogging torque reduction methods

2014 Electric Power Quality and Supply Reliability Conference (PQ), 2014
This paper considers the study of methods for reduction of the cogging torque in permanent magnet machines. Cogging torque has been analyzed to be reduced by slot skewing, width of slot opening, magnet pole radius and also by mounting of the magnets.

Ramp Automatic Torque Method

2017 International Conference on Robots & Intelligent System (ICRIS), 2017
The ramp automatic torque method in this paper is a new method to transform power torque on ramp for carbon-free car which is only driven by gravitational potential energy. This method is based on the torque structure and rope winding to achieve the good climbing ability of the carbon-free car. The mechanical structure includes starting wheel, climbing

Joint torque optimization method for space manipulator

2014 IEEE International Conference on Information and Automation (ICIA), 2014
Space manipulator is an integral part of space station in its life stages including construction, operation and development, during which there are tasks for the manipulator as manipulating light camera and also assembling cabins of weight. Workload range is so wide that optimization is necessary to be considered to improve execution performance on all
