Mathematical Simulation of the Synchronized Asynchronous Electric Drive [PDF]

open access: yesE3S Web of Conferences, 2020
At the end of the last century asynchronous motors with a phase rotor were most widely used among adjustable-speed AC drives. They were used for conveyors, transporters, cranes.

Associative cued asynchronous BCI induces cortical plasticity in stroke patients

open access: yesAnnals of Clinical and Translational Neurology, 2022
Objective We propose a novel cue‐based asynchronous brain–computer interface(BCI) for neuromodulation via the pairing of endogenous motor cortical activity with the activation of somatosensory pathways.

Angular Velocity's Neural Network Observer of the Electric Drive of TVR - IM Type Implemented in Software Environment LabVIEW [PDF]

open access: yes, 2016
One of the common ways to manage a smooth starting and stopping of asynchronous motors are soft-start system. For this provision is necessary to use a closed speed asynchronous electric drive of tiristor voltage regulator - induction motor (TVR-IM) type.

Songbird organotypic culture as an in vitro model for interrogating sparse sequencing networks [PDF]

open access: yes, 2017
Sparse sequences of neuronal activity are fundamental features of neural circuit computation; however, the underlying homeostatic mechanisms remain poorly understood. To approach these questions, we have developed a method for cellular-resolution imaging

Turn-to-turn fault protection technique for synchronous machines without additional voltage transformers [PDF]

open access: yes, 2017
This paper presents a novel protection technique for the detection of inter-turn faults in synchronous machines. It is based on the calculation of voltage in the stator windings from the usual phases and neutral voltage, typically available in ...
