Analysis of Copper Loss of Permanent Magnet Synchronous Motor With Formed Transposition Winding

open access: yesIEEE Access, 2021
In recent years, the hairpin winding flat wire motor has received more and more attention because of its high power density and high torque, but the problem of increased AC copper loss caused by the increase of its wire diameter has restricted the use of

Induction motor control through AC/DC/AC converters [PDF]

open access: yesProceedings of the 2010 American Control Conference, 2010
We are considering the problem of controlling inductions motors driven through AC/DC rectifiers and DC/AC inverters. The control objectives are threefold: (i) forcing the motor speed to track a reference signal, (ii) regulating the DC Link voltage, (iii) assuring a satisfactory power factor correction (PFC) with respect to the power supply net.

Dual-hemisphere anodal transcranial direct current stimulation improves bilateral motor synergies

open access: yesFrontiers in Psychology, 2023
Transcranial direct current stimulation (tDCS) is one of the non-invasive brain stimulation techniques that can improve motor functions. As bimanual motor actions require high motor cortical activations between hemispheres, applying bilateral anodal ...

Performance of halbach magnetized brushless ac motors [PDF]

open access: yesIEEE Transactions on Magnetics, 2003
In this paper, an anisotropic bonded NdFeB Halbach magnetised ring magnet, which is oriented in powder alignment system during injection moulding and subsequently impulse magnetised, is employed. The features of such a Halbach magnetised machine, in terms of the airgap field distribution, and the back-emf and cogging torque waveforms, etc.

The effect of precision and power grips on activations in human auditory cortex

open access: yesFrontiers in Neuroscience, 2015
The neuroanatomical pathways interconnecting auditory and motor cortices play a key role in current models of human auditory cortex (AC). Evidently, auditory-motor interaction is important in speech and music production, but the significance of these ...
