Torque-Sensorless Identification of IPMSM Torque Map

2021 IEEE Energy Conversion Congress and Exposition (ECCE), 2021
This paper analyzes the torque equation of an interior permanent-magnet synchronous machine (IPMSM), including magnetic saturation, spatial harmonics, and the variation of the magnetic energy. Based on the analysis, a torque-sensorless method is proposed to identify an IPMSM’s torque map.

Vowel recognition with four coupled spin-torque nano-oscillators

Nature, 2017
In recent years, artificial neural networks have become the flagship algorithm of artificial intelligence1. In these systems, neuron activation functions are static, and computing is achieved through standard arithmetic operations.

Magnetization switching by spin-orbit torque in an antiferromagnet-ferromagnet bilayer system.

Nature Materials, 2015
Spin-orbit torque (SOT)-induced magnetization switching shows promise for realizing ultrafast and reliable spintronics devices. Bipolar switching of the perpendicular magnetization by the SOT is achieved under an in-plane magnetic field collinear with an

Torque Fluctuation in Hydraulic Torque Converter

2019 IEEE 8th International Conference on Fluid Power and Mechatronics (FPM), 2019
In order to investigate the blade torque fluctuation mechanism and provide more insight into torque converter’s internal flow field, this paper established both single-blade passage and full-blade passage transient simulation model. The time dependent blade torque results from single blade-passage simulation method is actually the torque of those ...

A conductive topological insulator with large spin Hall effect for ultralow power spin–orbit torque switching

Nature Materials, 2017
Spin–orbit torque switching using the spin Hall effect in heavy metals and topological insulators has a great potential for ultralow power magnetoresistive random-access memory.

A new torque meter or torque magnetometer

Journal of Scientific Instruments, 1963
A torque meter is described which employs the principles used in work with resistance strain gauges to convert small torques developed in isolated specimens directly into electrical signals. The overall sensitivity and the maximum torque that can be measured with this meter can both be altered appreciably by suitable modifications in design, but for ...

An Improved Torque Sharing Function for Torque Ripple Reduction in Switched Reluctance Machines

IEEE transactions on power electronics, 2019
An offline torque sharing function (TSF) is introduced in this paper for torque ripple reduction in switched reluctance machines (SRM). This TSF uses static flux linkage characteristics of the machine obtained from finite element analysis or experiments ...

EMG-torque model to predict reflex mediated torque

Images of the Twenty-First Century. Proceedings of the Annual International Engineering in Medicine and Biology Society, 2003
An EMG (electromyogram)-torque model based on measurements during isometric muscle contractions was developed. The model was used to predict the reflex mediated torque during a stretch of the ankle dorsiflexors. The predicted values are compared to measured values, and it is proposed that the model can quantitate the mechanical component of the stretch
