Radial Force Density Calculation of Switched Reluctance Machines Using Reluctance Mesh-Based Magnetic Equivalent Circuit

open access: yesIEEE Open Journal of the Industrial Electronics Society, 2022
Acoustic noise and vibration is one of the shortcomings of a switched reluctance machine (SRM). Harmonics of the radial force waveform in the airgap excite the stator structure at different vibration modes with specific frequencies.

Radially anisotropic systems with forces: equilibrium states [PDF]

open access: yesJournal of Plasma Physics, 2015
We continue the study of collisionless systems governed by additive$r^{-{\it\alpha}}$interparticle forces by focusing on the influence of the force exponent${\it\alpha}$on radial orbital anisotropy. In this preparatory work, we construct the radially anisotropic Osipkov–Merritt phase-space distribution functions for self-consistent spherical Hernquist ...

Radial Force-Current Characteristics Analysis of Three-Pole Radial-Axial Hybrid Magnetic Bearings and Their Structure Improvement

open access: yesEnergies, 2016
The radial stator of three-pole radial-axial hybrid magnetic bearings (HMB) has three magnetic poles and the three magnetic poles are driven by a three-phase converter, so the three-pole radial-axial HMB has the advantages of compact structure, low cost,

Experimental system for measuring the force load of a single blade pump [PDF]

open access: yesMATEC Web of Conferences, 2023
Precise evaluation and anticipation of the radial and axial force loads acting on the impeller of a spiral casing pump are essential to ensure that the pump operates efficiently and dependably. This study presents an experimental system for measuring the

Eccentric Rotor Drop Dynamics Study of Vertical Maglev Bearing System

open access: yesLubricants, 2023
When considering the problem of a vertical magnetic levitation bearing system, the rotor eccentric fall is more likely to cause the failure of the protective bearing. In this paper, a rotor drop collision model and a protective bearing dynamics model are

Radial forcing and Edgar Allan Poe's lengthening pendulum [PDF]

open access: yesAmerican Journal of Physics, 2013
Inspired by Edgar Allan Poe's The Pit and the Pendulum, we investigate a radially driven, lengthening pendulum. We first show that increasing the length of an undriven pendulum at a uniform rate does not amplify the oscillations in a manner consistent with the behavior of the scythe in Poe's story.
