Ultralow-current density spin-torque diodes with high sensitivity
Applied Physics Letters, 2023Spin-torque diodes (STDs) offer the possibility of using spin torque to generate rectification voltage with promising applications in microwave detecting, energy harvesting, and neuromorphic computing. Here, we demonstrate a highly sensitive STD with ultralow current density based on a magnetic tunnel junction with perpendicular magnetic anisotropy. At

Comparative Analysis of High Torque Density PM Machines
2018 XIII International Conference on Electrical Machines (ICEM), 2018High torque density PM machines have attracted more and more attention recently, especially for the low-speed, high-torque application. In this paper, three high torque density PM machines are analyzed and compared, namely 12-slot/10-pole SPM, 16-pole transverse flux PM and 12-slot/22-pole flux modulation PM machines, with the specification of 30 kNm ...

High-torque density integrated electro-mechanical flight actuators
IEEE Transactions on Aerospace and Electronic Systems, 2002Electro-mechanical flight actuators (EMFAs) are core flight-critical vehicle components. Fly-by-wire or fly-by-light control of EMFAs is performed by flight management systems (flight, mission, propulsion, and integrated controls that manage any combination of specific flight, mission, and propulsion functions).

Design Optimization of a High Torque Density Spoke-Type PM Motor for a Formula E Race Drive Cycle
IEEE transactions on industry applications, 2018Performance trade offs for achieving high torque density and high drive-cycle efficiency in spoke-type permanent magnet (PM) motors are investigated. Unlike the traditional method, which relies on analytical equations, this trade-off study is conducted ...

A High-Torque Density Compliant Actuator Design for Physical Robot Environment Interaction
International Workshop on Advanced Motion Control, 2020Compared to the traditional industrial robots that use rigid actuators, the advanced robotic systems are mobile and physically interact with unknown and dynamic environments. Therefore, they need intrinsically safe and compact actuators.

Torque-Balanced High-Density Steady States of Single-Component Plasmas
Physical Review Letters, 2005Electron plasmas in a Penning-Malmberg trap are compressed radially using a rotating electric field (the "rotating-wall technique"). For large electric fields, plasmas can be compressed over a broad range of frequencies. This permits access to a novel high-density regime in which outward transport is insensitive to plasma density.

Magnetic Materials for Coaxial Magnetic Gear Torque Density Enchainment
2020 21st International Symposium on Electrical Apparatus & Technologies (SIELA), 2020In this paper are analyzed different soft and hard magnetic materials for coaxial magnetic gears torque enhancement. Estimation of material properties impact over the magnetic gear input and output torques is implemented by finite element method model. The modelling is carried out by Ansys-Maxwell software.
