Analysis of a Discrete Stator Hybrid Excited Flux Switching Linear Machine

open access: yesIEEE Access, 2022
A discrete stator hybrid excited flux switching linear machine (DSHEFSLM) is proposed in this paper. The proposed DSHEFSLM uses a discrete stator to reduce the iron loss and overall cost of the machine.

Thrust measurement of an ion thruster by a force probe approach and comparison to a thrust balance

open access: yesAIP Advances, 2022
A key parameter when characterizing the performance of an electric propulsion system is obviously its thrust. The thrust can be either determined directly using a so-called thrust balance or deduced from indirect measurements. Here, we present a comparison of thrust measurements of the same radio frequency ion thruster in the thrust range from 250 μN ...

Hydrodynamic Characteristics of an Electric Eel-Like Undulating Fin [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2023
Taking the electric eel as a bionic object, a long undulatory fin is designed. The turbulent model standard k-ε is used to solve the N‒S equation of a three-dimensional unsteady incompressible fluid. The hydrodynamic characteristics of the undulatory fin

Application of a compliant foil bearing for the thrust force estimation in the single stage radial blower

open access: yesOpen Engineering, 2015
The paper presents the application of a compliant foil bearing for estimation of the thrust force in a single stage radial blower under operational conditions. The bump foil of the thrust bearing behaves as a nonlinear spring. The knowledge of the spring

Prediction of thrust force and torque in canal preparation process using Taguchi method and Artificial Neural Network

open access: yesAdvances in Mechanical Engineering, 2021
Root canal preparation is a vital procedure during the treatment of pulposis and periapical periodontitis. However, the improper control of thrust force and torque in root canal preparation will cause nerve damage and cell necrosis. The aim of this study
