FEM ANALYSIS OF ANGULAR MISALIGNMENT FAULT IN SRM MAGNETOSTATIC CHARACTERISTICS [PDF]
Progress In Electromagnetics Research, 2010 This paper proposes magnetostatic analysis of Switched Reluctance Motor (SRM) under angular misalignment fault to evaluate the performance of the motor under difierent operating conditions. In this analysis three-dimensional flnite element method (FEM) is used to simulate reliable and precise model by considering the complex motor magnetic geometry ...

Dynamic analysis of coupling misalignment and unbalance coupled faults
Journal of Low Frequency Noise, Vibration and Active Control, 2019 Misalignment is a common fault occurring in the rotor system. However, the response characteristics have not been understood comprehensively, especially the relation between forces or torques and displacements, accelerations, or moments.

Dynamic Characteristics of Ball Bearing-Coupling-Rotor System with Angular Misalignment Fault
Nonlinear Dynamics, 2021 Abstract The rotor misalignment fault, which occurs only second to unbalance, easily occurs in the practical rotating machinery system. Rotor misalignment can be further divided into coupling misalignment and bearing misalignment. However, most of the existing references only analyze the effect of coupling misalignment on the dynamic ...

Paraxial orbital angular momentum beam under misaligned detection
Optics ExpressThis work presents an analytical framework for modeling a detected orbital angular momentum (OAM) spectrum of a Laguerre-Gaussian (LG) beam subject to tilt and lateral displacement. Firstly, we demonstrate that both types of misalignment generate OAM sidebands governed by the same functional form, each characterized by a distinct dimensionless ...

Efficiency Assessment of Induction Motors Drives Operating Under Shaft Misalignment Conditions
Advances in Electrical and Electronic Engineering, 2020 Historically, the negative effects of misalignment between the motor shaft and the load on the electric drives are well known. Vibrations, loss of life of couplings and deterioration of efficiency are some of these effects. Regarding this last point, the
